  در این پژوهش، کاربرد جاذب سیکلو دکسترین/نانو ذرات اکسید آهن سنتز شده به عنوان یک جاذب جدید برای حذف رنگ بنفش کریستال از محیط های آبی مورد بررسی قرار گرفت. این مقاله بر توسعه یک روش موثر برای به دست آوردن شرایط بهینه حذف با کمک امواج فراصوت برای حذف حداکثر رنگ بنفش کریستال بر روی CM-β-CD-Fe3O4NPs  در یک محلول آبی با استفاده از روش سطح پاسخ (RSM) تمرکز دارد. این جاذب جدید با تکنیک­های مختلف مانند FT-IR ،XRD  و SEM مشخصه یابی و ارزیابی گردید. تأثیر متغیرهایی مانند غلظت اولیه رنگ(X1) ،pH (X2) ، دوز جاذب (X3) و زمان فراصوت (X4)  با طراحی مرکب مرکزی (CCD) تحت روش سطح پاسخ مورد بررسی قرار گرفت. این فرآیند به صورت تجربی مدل­سازی شد تا متغیرهای مهم و فعل و انفعالات احتمالی آنها آشکار شود. شرایط بهینه سازی برای زمان تابش امواج فراصوت،pH ، مقدار جاذب وغلظت رنگ به ترتیب، 10 میلی­گرم بر لیتر، 6، 5 دقیقه و 025/0 گرم تعیین شد. در نهایت، نشان داده شد که حذف رنگ بنفش کریستالی توسط جاذب در pH برابر با 6 اتفاق افتاد. به وضوح ثابت شد که جذب رنگ مورد مطالعه با معادله سینتیکی شبه درجه دوم مطابقت دارد و همدمای لانگمویر داده های تعادل را توضیح می­دهد. حداکثر ظرفیت تک لایه جذب توسط جاذب  (qmax)برای رنگ مورد مطالعه در شرایط بهینه 100 میلی­گرم بر گرم بدست آمد. گرمازا بودن این فرآیند با مقدار منفی (ΔG˚، ΔH˚ وΔS˚) ثابت شد که نشان از میل جاذب سنتز شده  CM-β-CD-Fe3O4NPs برای حذف رنگ بنفش کریستال دارد.

  Introduction: Curdlan gum is a bacterial polysaccharidic biopolymer that is the result of β-(1→3)-D-glycosidic linkages. Due to its ability to curdle and the water-holding capacity, curdlan has applications in the manufacture of food products such as jelly, noodles, edible fibers. Curdlan is biodegradable, nontoxic and it has applications in the pharmaceutical industry because of its potent biological activities. For the first time, the present study is concerned with the synthesis, characterization, optimization of cultural conditions and modeling of curdlan production from Paenibacillus polymyxa using RSM. Materials and Methods: After preparation of the microorganism and the medium, Plackett–Burman design with 12 experimental runs was used to screen the effective factors through 11 variables of batch culture medium for curdlan production. Central composite design with 20 experimental runs was used for optimization of the effective variables. In addition, four characterization methods such as FT-IR, C-NMR, XRD and DSC were employed. Results: The result of the experiments showed that three nutritional factors (glucose, yeast extract and triton x-100) had the predominant effect on curdlan production. The maximum production of curdlan was 4.75 g/l from the optimum condition consisting of glucose (100 g/l), yeast extract (3 g/l) and triton x-100(2.5 g/l). In addition, the average molecular weight of curdlan was determined at 170 kDa by GPC. Conclusion: The results from this study have demonstrated that Paenibacillus polymyxa PTCC 1020 with more specific growth rate (µ) than previous studies is capable to produce curdlan gum and also the production of the synthetic curdlan was confirmed using qualitative methods of identification.   Manuscript profile

  Introduction: Spray drying is one of the most important ways to prevent waste of strategic food products and their shelf life extension.Optimization of operating conditions involved in this system can be a suitable background to produce products with ideal physicochemical quality. Materials and Methods: The effect of three operating parameters including inlet air temperature (IAT, 130-160°C), air flow rate (AFR, 2-4 m3/h) and feed flow rate (FFR, 4-10 mL/min) was investigated to attain the microencapsulated powders of red-beet extract containing functional pigment of betalain using RSM. The yield of produced powders, content of phenolic compounds and antioxidant activity of reconstituted extract were optimized. Results: The quadratic equations with high correlation coefficients (0.960-0.994) can well predict the optimal conditions to achieve the highest physicochemical efficiency. An increase in IAT and AFR had a significant effect on the decrease of the level of phenolic and antioxidant components of the obtained powders, while this trend led to an increase in the yield. The antioxidant and phenolic content of microencapsulated powders with low yield at higher FFRs are well maintained. The analysis of microscopy observations and particle size also confirmed the results clearly. The findings showed that the maximum physical yield (75%), phenolics content (1238.72 µg gallic acid/mL), and free-radical inhibition percentage (78.77%) can be obtained under the optimum conditions of 136.0°C IAT, 3.6 m3/h AFR, and 8.8 mL/min FFR. Conclusion: Production of high-quality powders microencapsulating red-beet extract under the optimal conditions might be a beginning to develop fortification of food products with the obtained powders.

  A novel metal–organic framework (MOF), with the formula [Cu(II)L]n (L= 4, 4′-diamino diphenyl sulfone), has been synthesized conventionally and hydrothermally methods and characterized by FT-IR, PXRD, EDX, and SEM techniques. The results MOFs were applied for photodegradation of Methylene Blue (MB). The influence of affecting variables, such as initial MB dye concentration (2–8mg L−1), Cu(II)-MOF mass (0.01–0.03 mg), pH (3.0–9.0), and time of irradiation (30–90 min). The photocatalytic degradation efficiency was investigated by the central composite design (CCD) methodology. The results of CCD analysis for optimum values of variables revealed that Cu(II)-MOF mass was 0.025g, the initial concentration of MB was 3.51 mg L−1, pH was 4.50 and irradiation time was 75 min.Under the optimum conditions, the photocatalytic MB degradation percentage at the desirability function value of 1.0 was found to be 70%. In addition, the obtained R2 value of 0.97 in the regression analysis showed a high photocatalytic efficiency of the proposed method for MB degradation. Manuscript profile
