Soybean is a functional food and it is characterized by providing several beneficial health effects allowing the expansion of research and development of functionalized products as alternative substitutes of dairy products. This study aimed to elaborate frozen yogurt enriched with calcium and added a mixed culture containing Lactobacillus acidophilus, Bifidobacterium and Streptococcus thermophilus microencapsulated, from aqueous extract of soybean. The micelles were prepared from albumin and collagen with the addition of over activated probiotic culture. The frozen yogurt was prepared on the basis of aqueous extract of soybean. The micelles of albumin and collagen were able to protect the probiotic microorganisms from cold keeping them viable for storage. The micelles were able to obtain a product with adequate physical, chemical and sensory characteristics for an edible frozen, what shows that soy frozen yogurt may be a good choice of product for the market.

Пивоваренная промышленность является источником производства такого побочного продукта, как пивная дробина, которая обладает ценными биохимическими и технологическими характеристиками. Представлены некоторые аспекты биотехнологии получения функциональной биодобавки с низкой кислотосвязывающей способностью на основе побочных продуктов пивоварения. Обозначены качественный состав используемой дробины и консорциума микроорганизмов, входящего в состав применяемого биоконсерванта, в технологии получения данной биодобавки. Для сквашивания пивной дробины подобран бактериальный концентрат, который состоит из смеси штаммовых культур молочнокислых кокков Lactococcus lactis subsp. lactis, молочнокислых бактерий Lactobacillus acidophilus, Lactobacillus plantarum и пропиновокислых бактерий Propionibacterium freudenreichii subsp. shermanii. Оценено влияние разработанной биодобавки совместно с модифицированным составом комбикормов на основные зоотехнические показатели цыплят-бройлеров в условиях напольного содержания. Введение биодобавки в состав рациона оказывает положительное влияние на основные зоотехнические показатели, в особенности в первые 2 фазы выращивания. Используемая добавка не ухудшает мясные и дегустационные качества мяса. Дозировка введения функциональной биодобавки составляла 3 % к массе корма. Показатели живой массы опытной группы цыплят, получавшей биодобавку, на 6,3 % превышали показатели контрольной группы. Показатели конверсии корма в 2 опытных группах также превышали данные контрольной группы на 9,04 и 5,85 %.

Our objective was to evaluate the effects of three doses of Lactobacillus acidophilus strain NP51 and a combination treatment of strains NP51 and NP45 on prevalence of Escherichia coli O157 in cattle. Three hundred steers were assigned randomly to 60 pens (five steers per pen) and received one of five treatments: (i) control, no added direct-fed microbial; (ii) HNP51, high dose of NP51 at 109 CFU per steer daily; (iii) MNP51, NP51 at 108 CFU per steer daily; (iv) LNP51, low dose of NP51 at 107 CFU per steer daily; and (v) NP51+45, NP51 at 109 CFU per steer daily and NP45 at 106 CFU per steer daily. All direct-fed microbial treatments included Propionibacterium freudenreichii at 109 CFU per steer. Individual rectal fecal samples were collected on arrival and every 28 days throughout the feeding period. Fecal and hide samples were collected on the day of harvest. Samples were analyzed for presence of E. coli O157 using immunomagnetic separation methods. Cattle receiving HNP51, MNP51, and LNP51 had a lower prevalence (P < 0.01) of E. coli O157 throughout the feeding period compared with the controls, and the dose response for NP51 was a linear decrease in prevalence with increasing dose (P < 0.01). No decrease in prevalence for cattle receiving the combination NP51+45 was detected compared with controls (P = 0.15). E. coli O157 prevalences averaged across collection times were 23.9, 10.5, 9.9, 6.8, and 17.3% for cattle in the control, LNP51, MNP51, HNP51, and NP51+45 groups, respectively. Least squares mean estimates of fecal prevalence at harvest of E. coli O157 were 31.7, 12.5, 17.4, 8.2, and 41.6% among cattle in the control, LNP51, MNP51, HNP51, and NP51+45 groups, respectively. Least squares mean estimates of the percentage of positive hide samples at harvest were 8.7, 5.9, 4.8, 3.4, and 8.6% among cattle in the control, LNP51, MNP51, HNP51, and NP51+45 groups, respectively. The greatest decrease in E. coli O157 carriage was achieved using NP51 at 109 CFU per steer.
