A recipe for cooked sausages of the herodietic direction using protein hydrolysate in the amount of 3%, 5%, and 7% of the mass of raw materials is proposed. The recipe is based on "Beef Sausage". Organoleptic evaluation of the prototypes showed that when protein hydrolysate was added in an amount of 7%, a specific taste characteristic of by-products was present in the prototype. Based on the sensory evaluation results, it was decided to continue the study of samples with the addition of 3% and 5% protein hydrolysate. The results of the study of the physicochemical parameters of the prototypes with the addition of protein hydrolysate 3% and 5%, showed the values of the mass fraction of protein 16.65% and 19.29%, fat 9.85% and 12.25%, carbohydrates 2.85% and 3.07% respectively, indicating an increase in the amount of protein and a decrease in the proportion of fat compared to the control sample. A significant increase in the content of such essential amino acids as lysine and valine and interchangeable amino acids as arginine, glycine, and serine in the test samples confirms that the protein hydrolysate introduced into the prototype is rich and well-balanced in amino acid composition. To study the effect of protein hydrolysate on the quality of meat products, the moisture binding capacity was determined, which was 3% and 5% in the experimental samples with the addition of protein hydrolysate – 75.62% and 79.13%, which is 3.4% and 8.2% higher than that of the control sample, respectively. The sample with the addition of 5% hydrolysate (80.01) has the greatest moisture-retaining ability, which is 9% higher than that of the sample with 3% hydrolysate and 15.8% higher than the control indicator. The study results of the fat-holding capacity in the samples also showed positive dynamics.
Производство сывороточных напитков вызывает интерес во всех странах с развитой молочной отраслью. Основа напитков -молочная сыворотка -является ценным вторичным сырьем молочной промышленности, которую утилизирует далеко не каждое предприятие. В мире данную проблему решают путем изготовления различных продуктов, в особенности напитков. Актуальность данных исследований заключается в переработке сыворотки, что способствует уменьшению вреда наносимым экологии отходами молочной промышленности. Также целенаправленно сывороточные напитки были обогащены растительными компонентами местного сочного растительного сырья, что позволит расширить ассортимент выпускаемой продукции. В качестве растительного сырья используются ягоды ирги, черноплодной рябины и облепихи, богатой полифенолами. Целью настоящего исследования является исследование и разработка технологий напиков на основе молочной сыворотки, обогащенных соками дикорастущих ягод. В статье представлены результаты по исследованию напитков в основу котрой входит молочная сыворотка, обогащенная натуральными соками из дикорастущего сырья Северного Казахстана. В исследовании использовались современные физико-химические, органолептические, технологические и статистические методы по исследованию сырья и готовой продукции. По полученным данным исследуемые напитки на основе сыворотки полностью соответствуют ГОСТ.
The article presents the results of experimental studies of serum beverage enriched with pine bark extract as a source of polyphenols. The effect of pine bark extract is investigated, its use in the production of serum beverage is justified, and the increase of essential amino acids, namely phenylalanine and tyrosine, is established. Enrichment with specially selected herbal components of the serum will allow the creation of new technologies of products with a given therapeutic and preventive direction.
The main strategy of the state policy in the nutrition is the natural products production that helps to reach the daily needs for nutrients, as well as the development and intensification of resource-saving technologies. It has been established that the production of cottage cheese and cheese has increased in Kazakhstan, therefore, the volume of whey, which is a waste product, has also increased. However, only 10% of the whey is recycled, and the rest is drained into wastewater, harming the environment. At the same time, it was established that whey is a valuable biological raw material. The most rational solution to this problem is the processing of whey, using modern methods, research and development of technology for low-calorie and functional foods based on whey. The purpose of this work is to research and develop modern methods of deep processing of whey and the production of natural low-calorie functional foods based on whey. Soft cheese from whey was selected as the studied products. The obtained samples of whey cheese were studied by composition, their energy value and amino acid composition were determined. According to the data obtained, it is possible to judge the usefulness and quality of the cheeses studied.
Kazakhstan is characterized by a wide variety of natural, climatic, economic, and ethnic factors that have a specific impact on the development of sheep farming. The production of dairy products from sheep is limited due to the low productivity of animals and the seasonality of milk production throughout the year, as well as the short lactation period. Also, one of the problems is manual milking of sheep, which does not allow obtaining sheep milk on an industrial scale. The market of dairy products, currently in the Republic of Kazakhstan is represented only by-products made from cow's milk, and at the same time, most of them are products made from cow's milk powder, so the development of products made from sheep's milk is an urgent task. In addition, sheep's milk is a national product, and one of the tasks is to revive the traditional products of the Kazakh people. The analysis of literature studies shows that in-depth studies of the chemical composition of sheep's milk have not been conducted in Kazakhstan. The chemical composition data obtained during the Soviet period only give an idea of the primary chemical parameters obtained by generally accepted basic methods and do not provide reliable information about the deep chemical composition of the milk of local ewes. According to the results of studies, the content of the essential amino acid valine in cow's milk (0.21 g/100g) is also lower than in sheep's milk (9.69-3.79 g/100g). Sheep's milk protein is digested in the human body by 99.1%, and cow's milk protein by 91.9%. According to world experts, one of the advantages of Kazakhstan's domestic milk products is its naturalness, a low share of the use of genetically modified organisms, and environmentally friendly pastures, due to which they receive high-quality and safe products. Therefore, the designated research topic and its analysis are appropriate and relevant.
