        Introduction: The super-beneficial food contains compounds with biological activity that promote health. Pasta is a suitable carrier for adding nutrients from various agricultural wastes. Nowadays, the use of synthetic antioxidants is limited due to the risks they have for health, therefore, the effort to find natural antioxidants of plant origin has increased.Materials and Methods: Based on the formulation, the effect of adding 0 to 0.5 percent of saffron residues, including petals, yellow stamens, and white roots, on the physicochemical, antioxidant, texture, and sensory properties by comparing averages using Duncan's test was performed at a confidence level of 95% using SPSS version 19 software and the analysis of the data obtained from the treatments of di-optimal mixed design was carried out using Design Expert software. The standard was checked in the form of di-optimal mixed design.Results: During the analysis of the results after optimization, from the total of 0.5% of the remaining saffron, the values ​​of 0.072% of the petal share, 0.028% of the white root share and 0.4% of the flag share were suggested by the software.Conclusion: The addition of saffron residue had no significant effect on the amount of moisture, water-soluble solids, weight and pH after cooking, while a significant effect was observed on the amount of total phenol, antioxidant, and anthocyanin, as well as the pasta texture. Enriched had less strength than the control sample and no significant difference was observed in sensory properties. Therefore, the addition of saffron residues while maintaining the physicochemical and sensory properties is important in the production of beneficial pasta. Manuscript profile

        Nanoemulsions are a colloidal dispersion of oil/water or water/oil phases stabilized by emulsifiers. The physicochemical properties of nanoemulsions have made them suitable candidates for the delivery of bioactive compounds. Oil-in-water nanoemulsions are proper carriers for hydrophobic and water-in-oil or water-in-oil-in-water nanoemulsions are good carriers for hydrophilic compounds. Saffron is an expensive bulbous stemless herb whose different bioactive ingredients including crocins, crocetin, safranal, picrocrocin, and essential oils have valuable nutritional, medicinal, pharmaceutical, and antimicrobial properties. The use of nanoemulsion technology is a promising approach for saffron processing. The emulsion liquid membrane is one of the effective techniques for extracting saffron bioactive. On the other hand, encapsulating saffron extract in nanoemulsion droplets can increase the stability, bioavailability, and controlled release of bioactive ingredients of saffron. Due to its inherent antimicrobial activity, saffron can be used in the form of nanoemulsion coatings to increase the quality and shelf life of food products. In this study, the existing studies on saffron nanoemulsions processing were reviewed. The application of nanoemulsion techniques for saffron extraction, saffron bioactive nanoencapsulation, as well as the probable preservative properties of saffron essential oils for food packaging have been discussed. This article also reveals information on two recent patents on the subject of saffron nanoemulsion by ultrasonic method. Manuscript profile

        The aim of this research is the identification of Saffron fields with Landsat-8 Satellite images in Torbat Heydarieh. In this regard, two approaches were utilized. The first approach was dealing with implementation of neural network, support vector machine, Mahalanobis distance, the minimum distance, maximum likelihood and parallelepiped classification methods to achieve land cover map. The second approach was to use  normalized difference vegetation index (NDVI) and soil adjusted vegetation index (SAVI) in the greenness peak time range of saffron. To prepare field data, coordinate and land cover class of 2587 points (1463 as training sample and others as tested) in a region with at least 30 m same land cover on January 25th, 2015 and May 9th, 2015 were recorded using a GPS receiver. Furthermore, statistics presented by ministry of Agriculture Jihad in the 2014-2015 crop year was used for evaluation. Two measures, including Kappa coefficient and overall accuracy were used for evaluation of the results. Support vector machine classification with overall accuracy of 95% and a Kappa coefficient of 90%, was the best method of the first approach. It shows a difference of about 18% in saffron area comparing with Jihad statistics. On the other hand, NDVI as the best method of second approach shows an area of 7118 hectares which comparing with Jihad statistics (7550 hectares), shows the error of 5.7%. Hence, the results indicate the performance of temporal vegetation indices in identification of saffron fields according to its phenology. Manuscript profile

        In order to study the effect of irrigation cycle and size of mother corms on flower yield and daughter corms in saffron, an experiment was conducted in Ghaen region in 2016 crop year using a split plot design. The main factor was irrigation cycles (2, 3 and 4 weeks) and the secondary factor was the size of corm (less than 4 g, 4 to 8 g, 8 to 12 and 12 to 16 g). The interaction effect of irrigation cycle and pistachio size on flower-related traits was insignificant and on female pistachio-related traits was significant. In mother corms less than 4 g and 4 to 8 g, irrigation cycle had no effect on the dry weight of daughter corms produced per square meter. Irrigation of mother corms 8 to 12 g and 12 to 18 g every two weeks, respectively, produced 3689 g and 4230 g of female corm per square meter, which increased by 7.5 and 9, respectively, compared to the four-week irrigation cycle. / 4% of this adjective. In mother corms less than 4 g, the two-week irrigation cycle increased the number of female corms per square by 7.5% compared to the four-week irrigation period and decreased the diameter of female corms by 9.5%, but in other sizes of mother corms There was no difference between irrigation cycles in terms of number of female corms per square meter and diameter of female corms.

        To study the effect of corm density on yield and qualitative traits of saffron (Crocus sativus L.) under different biological and chemical nitrogen fertilizers, a factorial experiment based on completely randomized block design with 3 replications was done in 2014 at Shahr-e-Rey region (Ghomi Abad). The experimental factors were: corm density in 3 levels (60, 120 and 180 corm per square meter) and biological and chemical nitrogen fertilizers in 4 levels (without fertilizer application, 150 kg.ha-1 of Urea, 5 L.ha-1 of Nitroxin and 75 kg.ha-1 of Urea +5 L.ha-1 of Nitroxin). The results indicated that the corm density affects number of daughter corm, fresh daughter corm weight, corm diameter, dry stigma and style weight, dry and fresh flower weight significantly. Mean comparisons also indicated that by increasing corm density from 6o to 180, saffron dry yield of saffron improved by 2.7 fold. However, increasing corm density reduced corm diameter, fresh corm daughter weight and their numbers per square meter. It can be concluded that nitroxin as an organic fertilizer, increases vegetative traits and saffron dry yield (stigma + style weight) to 2.08 kg.ha-1 and highly improves in qualitative traits like Safranal, Picrocrocin, and Crocin. It can be also said that combined use of nitroxin and urea would be an alternative method to reduce application of urea. Manuscript profile

        Abstract Introduction: Previous studies have shown that Alzheimer's disease can lead to dysfunction of sex hormones; however, consumption of antioxidant foods can prevent it. The aim of this study was to compare the effect of saffron extract and crocin on sex hormones in male rats with Alzheimer's disease. Materials and methods: This experimental study included 32 rats with Alzheimer's disease in four groups of 1) control 2) sham, 3) saffron and 4) crocin. Each group consisted of eight series.  The third and fourth Groups received 25 mg/kg of saffron and crocin peritoneally daily for eight weeks. Serum levels of FSH, LH and testosterone were measured by ELISA. To analyze the data, the groups were compared using one-way analysis of variance and Tukey's post hoc tests at a significance level of p < /em> < 0.05. Findings: Saffron had a significant effect on increasing FSH (P=0.001), LH (P=0.002) and testosterone (P=0.001). Like saffron, crocin had a significant effect on increasing testosterone (P=0.001), however, saffron’s effect was greater on increasing testosterone than that of crocin (P=0.001). Conclusion: Although crocin can improve serum testosterone levels in rats with Alzheimer's disease, saffron seems to have better effects on increasing sex hormones in Alzheimer's rats than crocin. Keywords: Saffron, Crocin, Alzheimer's, Sex Hormones   Extended abstract Introduction Increased life expectancy is associated with specific problems and diseases of old age. One of the major problems of this period is the prevalence of dementia. One of the most common dementias is Alzheimer's. Symptoms of Alzheimer disease include memory loss, judgment, reasoning, changes in mood and behavior, cognitive decline, memory impairment, sleep disorders, and personality and mood changes (2). In relation to Alzheimer's disorders, it has been shown that testosterone levels in people with advanced Alzheimer disease are significantly reduced as a sign of the progression of the disease (3). It has been reported that proper nutrition can improve Alzheimer's disorders to some extent, so the use of herbs can be effective in this regard. Saffron with the scientific name of Crocus sativus belongs to the lily family. Low-dose saffron is recommended for the treatment of pertussis, asthma, colds, menstrual pain, irregular menopause, infertility, inflammation, depression, headache, sore throat and nausea (7). Considering the improving effects of saffron and its active ingredients, the present study aimed to investigate and compare the effect of saffron extract and crocin on the sex hormones of male rats with Alzheimer disease.   Materialsand methods In this experimental study, 32 adult male Sprague-Dawley rats were purchased and kept in the laboratory for one week to be adapted to the new environment. Then, on the eighth day, the rats were injected intra- peritoneally with 8 mg/kg of trimethylettin chloride (TMT) (14) .After four days, its complete effect on the hippocampus was confirmed. Alzheimer patients were randomly divided into four groups of 1) control 2) sham, 3) saffron and 4) crocin. There were eight series in each group. Rats in groups 3 and 4 received 25 mg/kg of saffron and crocin peritoneally daily for eight weeks. To prepare crocin, 0.1 g of crocin by the name of Sigma Aldrich and Cat-No: 17024-4G was dissolved in 100 cc of normal saline and injected intra- peritoneally into rats at a dose of 25 mg/kg (8) Also, to prepare saffron extract, 9.2 g of saffron was poured into 1000 cc of distilled water and the mixture was incubated for 16 hours at 50 ° C. Then the solution was passed through a strainer and stored at 4 ° C. During the injection it was injected at a dose of 25 mg / kg peritoneally (9). At the end of the study, 48 hours after the last injection of saffron and crocin, rats were anesthetized with ketamine and xylazine. Blood samples were taken directly from the left ventricle of rats to measure the research variables. Serum levels of FSH and LH as well as serum testosterone levels were measured using a hormone test kit (Radim Italy) and a German IBL hormone test kit by ELISA respectively. The Shapiro-wilk test was used to identify a normal distribution. Also, One-way analysis of variance (ANOVA) with Tukey’s post- hoc test were performed (P≤0.05) for statistical analysis.   Findings The results of one-way ANOVA showed a significant difference in the serum levels of FSH, LH and testosterone among the four groups of the study (P=0.001). The results of Tukey’s post- hoc test showed that there was no significant difference in the serum levels of FSH (P=0.87), LH (P=0.94) and testosterone (P=0.99) between the control and sham groups ,though, serum FSH in saffron group was significantly higher than that of control and crocin groups (P=0.001);in addition, serum LH levels in saffron group were significantly higher than control group (P=0.002); moreover, serum testosterone levels in the saffron (P=0.001) and crocin (P=0.002) groups were significantly higher than the control group. Also, the saffron group was significantly higher than the crocin group (P=0.001).   Discussion The results of the present study showed that saffron had a significant effect on increasing FSH, LH and testosterone in rats with Alzheimer disease. The results of Modarresi et al.'s study showed that daily consumption of 25 and 50 mg per kg of body weight does not have a significant effect on increasing testosterone, FSH and LH hormones (6). However, consumption of 100 mg per kg of body weight leads to a significant increase in rats. Therefore, it seems that the dose of saffron consumption as well as the basal levels of sex hormones can be effective in saffron consumption. It has been reported that saffron ingredients such as crocin and crocetin can inhibit total cholesterol, low-density lipoproteins, malondialdehyde and increase the thickness of the aortic end layer as well as nitric oxide levels (13). The results of the present study also showed that crocin had a significant effect on increasing testosterone in rats with Alzheimer disease. Crocins, which are glycosides composed of carotenoids called crocins and sugars, are responsible for the color of saffron (18). Researchers believe that saffron and its ingredients can induce their metabolic and anti-necrotic regulatory effects by increasing antioxidants. Also in the present study, saffron had a greater effect on increasing testosterone in Alzheimer rats than crocin. Therefore, it seems that saffron can have more favorable effects on improving testosterone than crocin in Alzheimer disease.   Conclusion Although crocin can improve serum testosterone levels in rats with Alzheimer disease, saffron seems to have better effects on increasing sex hormones than crocin in Alzheimer rats.   Ethical Considerations Compliance with ethical guidelines The study was approved by the Ethics Committee of the Marvdasht Branch of Islamic Azad University.   Funding Isfahan Branch of Payame Noor University.   Authors' contributions Design and conceptualization: Tahereh Jaydari fard, Ali Asghar Pilehvarian; Methodology and data analysis: Tahereh Jaydari fard; Supervision and final writing: Ali Asghar Pilehvarian.   Conflicts of interest The authors declared no conflict of interest.

        Abstract Introduction: Nutrition and exercise are two factors affecting weight control. The aim of this study was to investigate the effect of eight weeks of selected Pilates trainings with saffron consumption on body composition of female. Materials and Methods: In this quasi- experimental study, 32 non-athlete female volunteers were divided into four groups of eight based on body weight, including 1) training, 2) saffron, 3) training + saffron and 4) placebo. Groups 1 and 3 performed Pilates trainings for 3 sessions per week . Each session lasted 60 minutes. Groups 2 and 3 consumed capsules containing 30 mg of saffron daily, and groups 4 received capsules containing placebo for 8 weeks. In the pre- test and 72 hours after the last training session and saffron consumption, the body composition of the subjects was measured using the BOCA X1 body composition device made in South Korea. To analyze the data, Shapiro- Wilk test, one-way ANOVA test with Tukey’s post- hoc test were used (P≤0.05). Findings: Pilates training, saffron consumption and Pilates training with saffron consumption had a significant effect on reducing the percentage of fat mass, increasing the percentage of total body fluid and the percentage of lean body mass (P=0.001). Also Pilates training with saffron consumption compared to consumption of saffron had a favorable effect on reducing the percentage of body fat mass (P=0.01) and increasing the percentage of total body fluid (P=0.009). Discussion: Although Pilates training and saffron consumption alone improve body composition, it seems that Pilates training combined with saffron consumption has more favorable effects than saffron. Keywords: Pilates Training, Saffron, Body Composition   Extended abstract Introduction The development of machine facilities, on one hand, has led to a better life and more leisure, and on the other hand, has reduced physical activity. This has led people to take an inactive life and has created a noticeable lack of movement in human life (1). Pilates is an exercise system founded in 1930 by Joseph Pilates. Today, what has made this unknown sport a complementary sport to the public and even home is the excellent performance of this sport and its application to all people of all ages and genders from a professional athlete to a housewife and its special condition like pregnancy (8). In addition to physical activity, one of the factors that can affect body composition is controlling and managing food intake. Some medical plants are more popular in today's society due to their weight loss effects. Saffron has been used as a well-known drug to treat many diseases throughout history and in different nationalities (3). Numerous therapeutic properties have been mentioned for saffron and its active ingredients, including anti-depressant, anti-anxiety and hypnotic effects, anti-seizure, muscle relaxant, analgesic and anti-inflammatory, antioxidant, anti- Alzheimer's, and anti-tumor and antitussives. Today, the use of natural and traditional supplements to perform sports skills better by improving body composition and increasing strength has become very popular. Considering the popularity and prevalence of Pilates in Iran in the last decade and the high tendency of people in this sport, especially in Iranian women, and the lack of studies on the interactive effects of Pilates training and crocin consumption on body composition, this study aimed to investigate the effect of Pilates along with saffron consumption on body composition of female.   Material and methods In this quasi-experimental study, 32 non-athlete women with mean age of 33±3.28 years were selected as the statistical sample. Inclusion criteria included no smoking, no cardiovascular disease and no weight loss drugs. At the beginning of the research, the informed consent form was completed by all subjects. Then, after measuring the demographic characteristics, the subjects were divided into four groups of eight based on body weight including 1) training, 2) saffron, 3) training + saffron and 4) placebo. During eight weeks, groups 2 and 3 consumed capsules containing 30 mg of saffron extract daily and group 4 consumed capsules containing placebo (13). Also groups 1 and 3 performed Pilates trainings for 3 sessions per week and 60 minutes each session (14). Each Pilates session consisted of 10 minutes of light warm- up, 15 minutes of stretching, 25 minutes of specialized exercises, and 10 minutes of cooling down. Before starting the research in the pre- test and 72 hours after the last training session and consumption of saffron, the body composition of the subjects was measured using the BOCA X1 body composition made in South Korea (2). Shapiro- Wilk, one-way ANOVA with Tukey's post- hoc tests were used to analyze the data (P≤0.05).   Findings The results showed that the percentage of the body fat mass in training, saffron and training + saffron groups compared to the control group in the post- test had a significant decrease than that of the pre-test (P=0.001). Also, the percentage of body fat mass in the training group + saffron in comparison with the saffron group in the post- test had a significant decrease than that of the pre- test (P=0.01). Percentage of total body fluid in the training + saffron group compared to the saffron group in the post- test had a significant increase compared to the pre- test (P=0.009). The percentage of lean body mass in the training, saffron and training + saffron groups compared to the control group in the post- test had a significant increase than the pre- test (P=0.001). The results also showed that the percentage of body fat mass in the training, saffron and training + saffron groups in the post- test was significantly reduced compared to the pre- test (P=0.001); Percentage of total body fluid in the training + saffron group in the post- test increased significantly compared to the pre- test (P=0.001). Also, the percentage of lean body mass in the training, saffron and training + saffron groups in the post- test significantly increased compared to the pre- test (P=0.001).   Discussion The results of the present study showed that eight weeks of Pilates training significantly reduced the percentage of body fat mass and increased the percentage of lean body mass. Consistent with the present study, eight weeks of Pilates training resulted in a reduction in body fat percentage, body mass index, waist-to-hip ratio, and abdominal fat (15). Regarding the use of exercises to control weight and body composition in women, it should be stated that due to the increasing prevalence of overweight in women and its consequences in adulthood, the use of an appropriate exercise to control weight and body composition is necessary. In fact, exercise can control weight and body composition by increasing calorie consumption. Also, the results of the present study showed that eight weeks of saffron consumption led to a significant reduction in the percentage of body fat mass and an increase in the percentage of lean body mass. To confirm the beneficial effects of saffron consumption, Hooshmand Moghadam and Gaini (2018) reported that daily consumption of 150 mg saffron led to a decrease in body fat percentage (12). It has been pointed out that the effects of saffron are due to the active ingredients of saffron, especially flavonoids (crocetin and crocin) as well as polyphenolic compounds, so that these substances can increase the antioxidant defense system (12). Regarding the interactive effects, the findings of the present study showed that Pilates training along with saffron consumption led to a significant decrease in the percentage of body fat mass and also a significant increase in the percentage of total body fluid and lean body mass. In addition, training along with saffron had a greater effect on reducing the percentage of body fat mass and increasing the percentage of total body fluid. Regarding these findings, it can be concluded that performing Pilates training along with saffron consumption has more favorable effects on body composition than saffron consumption alone.   Conclusion Based on the findings of the present study, it can be concluded that although Pilates training and saffron consumption alone lead to improved body composition, Pilates training combined with saffron consumption seems to have more favorable effects than saffron.   Ethical Considerations Compliance with ethical guidelines All subjects full fill the informed consent.   Funding No funding.   Authors' contributions Design and conceptualization: Setareh Sharafi, Ghobad Hassanpour; Methodology and data analysis: Setareh Sharafi; Supervision and final writing: Ghobad Hassanpour.   Conflicts of interest The authors declared no conflict of interest.

        Control of food borne diseases is a major concern and due undesirable side effects of chemical preservatives, there is more tendencies to natural preservatives such as spices for this purpose. Saffron is the most expensive spice that is is used as coloring and flavoring agent in foods. The aim of the present study was investigate antibacterial effects of hydro alcoholic extracts of saffron against pathogenic bacteria especially food poisoning species. For this purpose, one gram of finely powdered saffron was mixed with 10 ml of 2:8 (v/v) water- alcohol (ethanol or methanol) solution and mixed gently. Following incubation at room temperature, the suspension was centrifuged and the extract of saffron was harvested and dried. Sterile blank discs were saturated with extracts and their effects were evaluated in standard disc diffusion assay against six gram positive and six gram negative bacterial species. Simultaneously, the effect of standard antibiotics was evaluated against tested bacteria. The results revealed that Staphylococcus aureus, Bacillus anthracis, Bacillus cereus, Listeria monocytogenes and Brucella melitensis were the most susceptible species to ethanolic and methanolic extracts of saffron while Proteus mirabilis and Salmonella Typhi were resistant. The antibacterial effects of extracts were noticeable with regard to the standard antibiotics. All of the susceptible species in this study are important food borne pathogens and it is possible to use saffron as a natural preservative in food industry in order to control food borne pathogens.

        Experimental autoimmune encephalomyelitis (EAE) is an inflammatory demyelinating disease of central nervous system and commonly used as an animal model for multiple sclerosis (MS). Multiple sclerosis is a disabling neurodegenerative disease in human being. Inflammation is a key event in both EAE and MS, which leads to demyelination and subsequent disability. It is shown that Crocus sativus L. stigma (saffron) extracts have anti-inflammatory activity in rats and mice. There are modern pharmacological evidences for anti-tumour, chemopreventive and genoprotective effects as well as radical scavenger properties of saffron extracts or its constituents. We observed that both therapeutic doses of dexamethasone and methanol extracts of saffron stigma at 100 mg/kg and more prevented EAE from progression significantly in pMOG-immunized female C57BL/6 mice. Aqueous maceration extract of Crocus sativus L. did not prevent EAE progression. These results suggest that saffron may attenuate symptoms of EAE by its anti-inflammatory activity.

        The aim of this study was to investigate the effect of aerobic exercise and oral consumption of Iranian saffron flower on Nesfatin-1 and Omentin-1 in obese women with type 2 diabetes. Forty-four people from the research community were randomly selected and divided into four groups (11 people in each group) 1. supplement + exercise, 2. exercise + placebo, 3. placebo and 4. supplement. The training protocol in the first session included 20 minutes of activity with an intensity of 40 to 45% of the maximum heart rate, increased by 5 minutes every week for 9 weeks and 5% of the intensity of activity every two weeks. Due to the lack of regular physical activity and low physical fitness of these people, aerobic exercise started with a heart rate of 40-45% of the maximum heart rate and the intensity and duration of exercise increased gradually and continuously every week. The placebo and saffron supplement groups were asked not to exercise during this period. The amount of 200 mg of powdered saffron flower in capsules of the same color and shape with placebo capsules containing 200 mg of wheat flour was prepared. The results within the group indicated a significant difference between the pre-test and post-test of omentin-1 and nesfatin-1 in all groups except the placebo group (P≤0.05). Besides, the comparison of the results between groups in the variables of omentin-1 and nesfatin-1 showed a significant difference between all groups receiving the intervention in the post-test phase with the placebo group (P=0.0001). Although exercise has benefits in improving diabetics, but according to the results of the present study, supplementation with saffron extract can lead to a further increase in omentin-1 and nesfatin-1.

        Understanding of the factors importing quantity and quality of saffron plant to obtain desirable performance is important. Among these factors is use of different fertilized and corm densities. To study the effect of corm density and urea fertilizer as well as bio fertilizer nitroxin on the performance, vegetative organ, and photosynthetic pigments of saffron plant, a research was conducted in randomized complete blocks design in a field located in Davoodabad, Gharchak. Treatments included three levels of corm densities (60, 120, 180corm per m2) and four levels of fertilizers: control, urea fertilizer (150kg.ha) nitroxin bio fertilizer (5 L.ha) as well as urea nitroxin (75 kg.ha) and nitroxin (2.5 L.h). The results showed that all treatment had significant effects on all traits at 1% cultivation of high density of saffron corms (180m2) had cumulative positive effect on all traits but leaf length. It should be noted that the interactive effect of fertilizers and corm density on most of traits was significant. The maximum number of flowers per corm planting density of 180 per square meter and fertilizer use Nitroxin with the 64.97 and the least number of flowers per corm density of 60 per square meter and not using fertilizer with an average of 3.30 goals per square meter, respectively. The highest and lowest of 2.93 and 0.74 respectively kilograms of yield per hectare were achieved in treatments D3F3 and D1F1. Manuscript profile
