  Introduction: The aim of this study was to produce low-calorie jelly using sour tea as a natural coloring agent, gelatin extracted from chicken skin with stevia as sweetener. Materials and Methods: Chicken skin gelatin was extracted by using alkaline-acid pre-treatment with 1 N of NaOH and 0.05 N hydrochloric acid. Gelatin was used at the concentrations of one and two percent (wt.%), Stevia with 0 to 100% replacement rates with sugar and sour tea at 20 wt.% for 100 g of jelly and 48 hours after gel production, pH measurement, Brix, moisture content, acidity, water activity, tissue stiffness, color, sensory analysis and microbial tests were performed. Experiments were conducted in a completely randomized design based on factorial experiment using SPSS software and compared with Duncan's multiple range test at 5% probability level. Results: The results showed that by increasing gelatin concentration and the level of sucrose replacement with stevia did not have a significant effect on pH. By increasing the concentration of gelatin, texture hardness and L*, significantly increased and moisture decreased (p < 0.05), whereas the parameters of brix, water activity, a* and b* of samples were not significantly different (p> 0.05). By increasing the levels of sucrose replacement with stevia and decrease of solids content the moisture, water activity and L *, a *, b * factors were significantly increased and the brix of the samples decreased. Conclusion: Sensory and physicochemical properties of sour jelly samples showed that using chicken skin gelatin and stevia as sweetener could be a good alternative to low-calorie jelly formulation by preserving physical, chemical and sensory properties. Due to medicinal properties, sour tea provides beneficial contribution to sour jelly product Manuscript profile

  In order to investigate the effect of biochar fertilizer and humic acid foliar application on quantitative and qualitative characteristics of Roselle (Hibiscus sabdariffa) a split plots experiment in a randomized complete block design was performed with three replications in the Research Field of Islamic Azad University, Arak Branch during 2017-2018 and 2018-2019. Experimental factors included 3 levels of biochar (non-consumption or control, 4 tons ha-1, and 8 tons ha-1) and the second factor of foliar spraying of humic acid 82% at 4 levels (non-consumption or control, 100 mg/l, 200 mg/l, and 300 mg/l. Interaction of biochar and humic significantly affected fruit yield. In the treatment with 8 t/ha biochar and 200 mg/l humic acid, the fresh weight of shoots was 465.1 g plant, showing an increase by 32% compared to the minimum value obtained from fertilizer control. At different levels of humic acid, consumption of 8 tons per hectare biochar always increased fruit yield compared to non-biochar treatment and consumption of 4 tons per hectare biochar. The interaction of biochar and humic acid on color intensity was significant. In the combined treatment of 8 tons per hectare of biochar and 100/l of humic acid, a red index of 14.67 was obtained. At different levels of humic acid, consumption of 8 tons per hectare biochar increased the red color index. Considering the fact that the intensity of red color in Roselle indicates the quality of the product, the consumption of 300 mg per liter humic acid and 8 tons per hectare biochar increased this trait, improving its functional traits.

  This study was conducted to investigate the effects of sour tea powder on growth performance and immune responses of broiler chicks under conditions challenge with ascites. 400 broiler chicks were studied in arrangement of 4 experimental diets including: Treatment 1: Positive control group (without induction of ascites and without powder), treatment 2: Negative control group (induction of ascites without powder), Treatments 3 and 4) 1% and 2% sour tea powder groups with ascites induction, and inclusion of 1% and 2% tea powder. This study was conducted for 42 days and the induction of ascite was started from day 8. This study was conducted in form of a completely randomized design with 4 treatments and 5 replications. Performance parameters (body weight, feed intake and feed conversion ratio), immune responses against SRBC, weight of immune organs (spleen, thymus and bursa) and heart indexes were investigated. The results showed that the induction of ascites decreased body weight and increased feed conversion ratio in finisher period. The induction of ascites also decreased relative weight of heart indexes, immune organs and antibody titer (p<0.05). Dietary inclusion of 2% plant powder increased growth performance in finisher and total periods. It also improved relative weight of immune organs and antibody titer against SRBC. In conclusion, adding 2% Sour tea powder into diet is suggested to improve immune responses and growth performance under ascites condition. Manuscript profile
