Technology of soy-milk combined product for special purpose with milk whey protein hydrolysate

Цель работы – разработать технологию нового продукта с повышенным содержанием белка. В статье представлена технология производства майонеза, обогащённого сывороточным белком альбумином. При разработке технологической схемы производства майонеза с альбумином была принята традиционная схема, в которую были добавлены дополнительные операции по подготовке альбумина: размораживание (дефростация), обезвоживание. В ходе исследований были проведены выработки контрольного и трёх опытных образцов с различным процентным содержанием альбумина (5, 10 и 15%). По результатам проведённых исследований нами рекомендуется вводить в рецептуру майонеза не более 10% альбумина. По органолептическим показателям, влажности и кислотности разработанный нами продукт отвечает требованиям ГОСТ 31761-2012 «Майонезы и соусы майонезные. Общие технические условия». Мы считаем, что введение в рецептуру альбумина позволит увеличить в майонезе долю легкоусвояемого белка, что, несомненно, повысит пищевую и биологическую ценность готового продукта. The goal of the work is to develop the technology of a new product with an increased protein content. The technology for the production of mayonnaise enriched with whey protein albumin is presented in the article. When developing the technological scheme for the production of mayonnaise with albumin, a traditional scheme was adopted, in which additional operations for the preparation of albumin were added: defrosting (defrostation), sublimating. During the researches the production of control and three experimental samples with different percentages of albumin (5, 10 and 15%) was carried out. According to the results of the research carried out, we recommend introducing no more than 10% albumin into the mayonnaise formula. According to organoleptic indicators, humidity and acidity, the product developed by us meets the requirements of GOST 31761-2012 "Mayonnaise and mayonnaise sauces. General Specifications". We believe that the addition of albumin to the formula will increase the proportion of easily digestible protein in mayonnaise, which will undoubtedly increase the nutritional and biological value of the finished product.

Abstract Purpose To examine whether calcium type and co-ingestion with protein alter gut hormone availability. Methods Healthy adults aged 26 ± 7 years (mean ± SD) completed three randomized, double-blind, crossover studies. In all studies, arterialized blood was sampled postprandially over 120 min to determine GLP-1, GIP and PYY responses, alongside appetite ratings, energy expenditure and blood pressure. In study 1 (n = 20), three treatments matched for total calcium content (1058 mg) were compared: calcium citrate (CALCITR); milk minerals rich in calcium (MILK MINERALS); and milk minerals rich in calcium plus co-ingestion of 50 g whey protein hydrolysate (MILK MINERALS + PROTEIN). In study 2 (n = 6), 50 g whey protein hydrolysate (PROTEIN) was compared to MILK MINERALS + PROTEIN. In study 3 (n = 6), MILK MINERALS was compared to the vehicle of ingestion (water plus sucralose; CONTROL). Results MILK MINERALS + PROTEIN increased GLP-1 incremental area under the curve (iAUC) by ~ ninefold (43.7 ± 11.1 pmol L−1 120 min; p < 0.001) versus both CALCITR and MILK MINERALS, with no difference detected between CALCITR (6.6 ± 3.7 pmol L−1 120 min) and MILK MINERALS (5.3 ± 3.5 pmol L−1 120 min; p > 0.999). MILK MINERALS + PROTEIN produced a GLP-1 iAUC ~ 25% greater than PROTEIN (p = 0.024; mean difference: 9.1 ± 6.9 pmol L−1 120 min), whereas the difference between MILK MINERALS versus CONTROL was small and non-significant (p = 0.098; mean difference: 4.2 ± 5.1 pmol L−1 120 min). Conclusions When ingested alone, milk minerals rich in calcium do not increase GLP-1 secretion compared to calcium citrate. Co-ingesting high-dose whey protein hydrolysate with milk minerals rich in calcium increases postprandial GLP-1 concentrations to some of the highest physiological levels ever reported.

Whey Protein Hydrolysate

Sarcopenia, a loss of skeletal muscle mass and function, is prevalent in older people and associated with functional decline and mortality. Protein supplementation is necessary to maintain skeletal muscle mass and whey protein hydrolysates have the best nutrient quality among food proteins. In the first study, C57BL/6 mice were subjected to immobilization for 1 week to induce muscle atrophy. Then, mice were administered with four different whey protein hydrolysates for 2 weeks with continuous immobilization. Among them, soluble whey protein hydrolysate (WP-S) had the greatest increase in grip strength, muscle weight, and cross-sectional area of muscle fiber than other whey protein hydrolysates. To investigate the molecular mechanism, we conducted another experiment with the same experimental design. WP-S significantly promoted the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) pathway and inhibited the PI3K/Akt/forkhead box O (FoxO) pathway. In addition, it increased myosin heavy chain (MyHC) expression in both the soleus and quadriceps and changed MyHC isoform expressions. In conclusion, WP-S attenuated muscle atrophy induced by immobilization by enhancing the net protein content regulating muscle protein synthesis and degradation. Thus, it is a necessary and probable candidate for developing functional food to prevent sarcopenia.
