The presence of other cell wall-degrading enzymes identified by proteomics, reinforce the combination for obtaining clarified and depectinized juice in a single step.Spirulina platensis is having high nutritive value due to pigments such as chlorophyll-a, phycobiliproteins (especially phycocyanins) and carotenoids. In our present work, C-phycocyanin (C-PC) was extracted from dry biomass of Spirulina platensis. C-PC being heat sensitive, reiterates the need for additional protection during drying (micro encapsulation). Accordingly, a novel method employing aqueous two phase systems (ATPSs) as carrier materials to achieve double encapsulation was studied for the first time. PEG 4000/Potassium phosphate and PEG 6000/Dextran were used at already standardized tie line length, at different volume ratios (by varying the total phase composition). ATPS at each volume ratio acted as different carrier materials offering varied degree of heat protection during double encapsulation while maltodextrin, being the conventional carrier material, was used for comparison. The best results of spray dried powders using PEG (4% w/w)/Potassium phosphate salt (18%, w/w) and PEG (6%)/Dextran (10%, w/w) phase systems as carrier materials were compared with conventional encapsulation (MDX as a carrier material) and freeze dying as control. PEG/Dextran as a carrier material with volume ratio of 0.25 resulted in the highest retention of blue colour (b*value), purity (0.43) as well as yield (YEP) of 94.99% w/w of C-PC, which could be stored for 6 months without much reduction from initial powder characteristics. From the overall results, it can be concluded that ATPS can be used as an effective carrier material for double encapsulation of biomolecules such as C-PC with additional benefit of enhancing the purity.In the current study, response surface methodology was executed to optimize the ingredient formulation and process conditions production such as wheat dextrin, starter culture and incubation time on the responses such as pH, viscosity, syneresis, overall acceptability, L* value and hardness of the wheat dextrin yogurt. The analyses showed that the wheat dextrin yogurts have a pH from 4.09 to 4.98, viscosity from 10,649.5 to 21,410.1 cP, syneresis from 2 to 26.67%, overall acceptability from 5.3 to 7.9, L* value from 81.2 to 84.3 and hardness from 506 to 5943.3 g during the optimization process. From the variance analysis, the R2 of five response variables except hardness is more than 0.73, which indicates the model explained a high proportion of variability. To conclude, based on the response surface 3D plot of the pH, viscosity, syneresis, overall acceptability, L* value, and hardness evaluation, the optimum value for the independent variables are wheat dextrin of 15 g, a starter culture of 25 g, and an incubation time of 8 h for the wheat dextrin yogurt.This work intended to compare dromedary yogurt's characteristics obtained by a co-fermentation process with plant (carob powder) or autochthonous bacteria (Enterococcus faecium and Streptococcus macedonicus). For this reason, the ultrafiltration process (UF) is applied to increase the rate of total solids in dromedary milk within the margin needed to prepare a yogurt. Carob powder or autochthonous bacteria were incorporated at the level of 2% in UF milk. Then mixtures were fermented with the strains Lactobacillus bulgaricus and Streptococcus thermophiles, and the obtained products are named CFC (yogurt with carob), CFS (yogurt with autochthonous strains) and control (yogurt with only L. bulgaricus and S. thermophilus) respectively. All along of 3 weeks at cold, CFC and CFS maintained Streptococcus at appropriate levels (>8 log CFU/g). Moreover, CFC showed the lowest syneresis, highest cohesiveness and springiness values, and oleic acid (C181n9; 26.315%). However, CFS yogurt resulted in higher volatile compound formation than CFC and control, where isobornyl propionate was the major one.The present effort was to obtain extracts from various fruit by-products using three extraction systems and to evaluate their polyphenolic content, antioxidant, and α-glucosidase inhibition activity. The fruit by-products were pre-processed by washing, drying, and milling methods to produce the powder. The powder samples were used to obtain extracts using pressurized hot-water (PHWE), enzyme-assisted (EnE) and organic solvent extraction (OSE) systems. The total phenolic content (TPC), total flavonoid content (TFC), antioxidant and α-glucosidase inhibition activity in all samples were assessed by Folin-Ciocalteu, AlCl3 colorimetric, DPPH· & ABST·+ and α-glucosidase inhibitory methods. The results showed that the extracts of peel, seed and other by-products exhibited outstanding TPC, TFC, and strongest antioxidant and α-glucosidase inhibition activity, eventually higher than edible parts of the fruits. check details For instance, the highest TPC among the peels of various fruits were in mango peel (in all cultivar) followed by litchi peel, banana peel cv. sagor, jackfruit peel, pineapple peel, papaya peel, banana peel cv. malbhog and desi on average in all tested extraction systems. PHWE system yielded significantly (p  less then  0.05) higher TPC and TFC than other extraction systems. In case of misribhog mango variety, the TPC (mg GAE/g DM) in peels were 180.12 ± 7.33, 73.52 ± 2.91 and 36.10 ± 3.48, and in seeds were 222.62 ± 12.11, 76.18 ± 2.63 and 42.83 ± 12.52 for PHWE, EnE and OSE respectively. This work reported the promising potential of underutilized fruit by-products as new sources to manufacture ingredients and nutraceuticals for foods and pharmaceutical products.Popping/puffing have been traditionally practiced for enhancing storage life, improving organoleptic properties and ease of incorporation in ready-to-eat-foods. Currently, batch type sand and electric popping/puffing machines involving conduction mode of heat transfer are employed. The major drawbacks of these methods are high-energy consumption, scorching of grains, non-uniform product quality, contamination (by sand/ash) and problems in scale-up. Since fluidization is known to increase heat and mass transfer, a continuous fluidized popping/puffing machine (capacity 10-20 kg/h) involving convective mode of heat transfer is designed/developed. Hot-flue gas generating from burning of LPG was used as the eco-friendly fuel. Process parameters such as expansion ratio, fluidization velocity, terminal velocity, carry over velocity, bulk density and voidage were estimated for un-popped and popped/puffed rice, maize, jowar (sorghum) and paddy. Fluidization and carry over velocities for these grains were in the range of 4.
