Milk Whey Protein

Two common genetic variants of β-lactoglobulin (β-lg), A and B, exist as co- dominant alleles in dairy cattle (Aschaffenburg, 1968). Numerous studies have shown that cows homozygous for β-lg A have more β-lg and less α-lactalbumin (α-la) and casein in their milk than cows expressing only the B variant of β-lg (Ng-Kwai-Hang et al. 1987; Graml et al. 1989; Hill, 1993; Hill et al. 1995, 1997). These differences have a significant impact on the processing characteristics of the milk. For instance, the moisture-adjusted yield of Cheddar cheese is up to 10% higher using milk from cows of the β-lg BB phenotype compared with milk from cows expressing only the A variant (Hill et al. 1997). All these studies, however, describe compositional differences associated with β-lg phenotype in established lactation only. No information is available on the first few weeks of lactation, when there are marked changes in the concentrations of β-lg and α-la (Pérez et al. 1990).

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.

High Protein Concentration

SUMMARYColostral whey protein levels do not change during the first 4 hr from the start of parturition when suckling is prevented. Both early and late-born piglets returned to the sow at the end of this period are able to suck colostrum of a high protein concentration. Removal of piglets from the sow and the presence of an attendant did not affect the farrowing process.

Aim. The article deals with the study of technological approaches to the quality and deve­lopment of a functional fermented milk product for specialized sports nutrition. Materials and methods. Skim milk, whey protein concentrate, and starter cultures (DELVO-YOG®, DIRECT SET) were used for the study. Bifidobacteria (Bifidobacterium animalis) were introduced as a probiotic. Creatine monohydrate (Creatine Powder C4N9O2N3, USA) was used as an element of sports nutrition. The fruit fillers (“Green Apple”, “Blueberry”, produced by “Zuegg”, Italy) were also introduced into the product. The research was conducted using standard and original methods, mathematical modeling, and statistical processing of experimental data. Results. The obtained data on the physiological effects of proteins, fats, carbohydrates, and nutrients, enhancing the adaptive capacity to the physical and neuro-emotional stress, indicate the need for their use in the technology of specialized food for athletes. Technological approaches to the quality of a functional fermented milk product for sports nutrition were studied. Based on a combination of milk, whey protein concentrate, starter cultures, and bifidobacteria, a fermented milk product was designed. This product is intended for athletes during training, competition, and recovery. The introduction of creatine monohydrate into the milk base allowed enriching the product with amino acids. Conclusion. This study is of great interest in terms of getting yogurts with the textural properties similar to the traditional ones but with the use of functional ingredients. The study also contributes to the development of food technologies and products for sports nutrition.
