PRODUCTION TECHNOLOGY OF FRUIT-FILLED COTTAGE CHEESE FOR BABY FOOD OVER 6 MONTHS OF AGE

Currently, cottage cheese is one of the leading dairy products for infants’ nutrition. Today, the urgent task is to expand the range of sour-milk products by developing a technology for cottage cheese production with the addition of a fruit filler. The object of research is cottage cheese for the diet of children over six months. The cottage cheese is produced from whole milk subjected to high-temperature treatment with the use of starter microorganisms and with the addition of fruit filler “Banana”. The children’s curd recipe developed by the authors included the following raw materials and components: milk with the mass fraction of fat 3.4 %, skim milk with the mass fraction of fat 0.05 %, direct injection starter Flora C-170, fruit filler “Banana”. Production technology included the following stages: receiving and preparing raw materials, normalization of milk, homogenization, pasteurization and cooling of the normalized mixture, fermentation, ultrafiltration of curd clot, cooling and ripening of the product. The authors conducted laboratory studies of cottage cheese to assess the quality and safety of the resulting product. The products meet the requirements of GOST 32927-2014 for organoleptic indicators: taste and smell, appearance and consistency, colour. The products also meet the needs of the Technical Regulations of the Customs Union (TR CU) 033/2013 “On safety of milk and dairy products” in terms of microbiological and antibiotic content.

Improvement of cottage cheese technology

In recent years, the prospect of improving the technology of cereal cottage cheese using linseed oil has been widely used to improve and maintain their quality, increase the biological and nutritional value of the finished product, and increase the shelf life. In the course of the work, the number of components of the cottage cheese with the addition of linseed oil was selected, a technological scheme was developed. Physicochemical and microbiological changes were investigated, and the energy value of the resulting product was calculated. (per 100 g of product: 774kj/178 kcal: fats 10.42 g (52%); protein 18 g (40%); carbohydrates 3.3 g (8%)).

Consumption of Dairy Products and the Risk of Developing Breast Cancer in Polish Women

Lack of consistency in the relationship between dairy products consumption and breast cancer (BC) risk motivated us to evaluate this association in a case-control study of BC among Polish women. The study includes 1699 women 26–79 years of age, 823 BC cases identified in Cancer Registries and 876 randomly selected controls from the national population registry. Using a validated, semiquantitative food frequency questionnaire (FFQ), the consumption of dairy products was collected for a time period of 10–15 years prior to BC diagnosis. We used logistic regression, adjusting for potential confounders, to assess the relationship between total dairy consumption as well as individual dairy groups of milk, cottage cheese and hard cheese and BC risk for premenopausal and postmenopausal women. For total consumption, a significant decrease in BC risk was observed with increased consumption of one serving/week, OR trend = 0.98, 2% decrease in risk, for premenopausal women only. For milk, a significant decrease in BC risk was observed for an increase in consumption of one glass/week, OR trend = 0.95, 5% decrease, in both strata of menopause. In contrast, for hard cheese, a significant increase in the risk of 10% was observed only in premenopausal women, OR trend = 1.10. Cottage cheese consumption significantly reduced BC risk by 20%, OR trend = 0.80, for an increase in one serving/week for postmenopausal women only. Our results show that individual dairy products have a statistically significant but bi-directional relationship with BC risk, which differs for premenopausal and postmenopausal women.

CURRENT TRENDS OF DAIRY MARKET DEVELOPMENT

The conducted research testifies to the significant influence of modern events on the dairy market development both in Ukraine and in the whole world. In the dairy industry of Ukraine, there is a significant crisis deepening: there is a tendency to reduce the number of cows and, consequently, reduce the raw milk production. Key indicators of the dairy industry continue to decline. The article covers the main modern market’s tendencies of dairy products development. The most important among them are: a significant increase in the weighted average price of raw materials for the dairy industry – raw milk; reduction of dairy products sales in general in small packages; increase in butter and hard cheeses consumption and gradual decrease in drinking milk consumption, fermented products, dairy drinks, as well as soft cheeses (cottage cheese); changing the range of desserts from drinking versions to versions of spoons, flavors, types of additives and forms of packaging; the use of cereal ingredients, crispy, muesli, which will play the role of a healthy snack; increasing consumption of healthy foods that increase resistance to disease; acquisition of lactose-free products’ new value; development of alternative plant-based products; growth of services via the Internet; increasing the role of "clean" label; introduction of new products and tastes that are especially appreciated by consumers; growing interest in long-ripening cheeses; sales growth in the "free from" segment; development of the natural yogurt market; special attention to the preferences of the elderly; the desire for more complex, interactive and green packaging of dairy products with additional features. Despite the deepening crisis in the dairy industry, the widespread introduction of various marketing tools, the introduction of innovations with an emphasis on organic dairy products, whose market is growing every year, will not only keep sales at the previous level, but while taking advantage of new dairy products’ consumer needs and new opportunities, redistribute income and expand the economic activity of dairy enterprises. And the adoption of Law № 6155 is a significant factor in improving the economic situation of food producers, establishing a fair distribution of value added in the producer-processor-consumer chain, ensuring food security and taking into account changes that comply with EU directives.

The influence of different genotypes of kappa-casein and beta-lactoglobulin on the productivity of cows of Ayrshire, Holstein and Yaroslavl breeds

Under the conditions of intensification of dairy cattle breeding, genetic markers of protein-milk content, namely allelic variants of kappa-casein and beta-lactoglobulin, are increasingly used. They are established by the method of DNA testing on blood samples of breeding animals. This method is also being introduced in our country, which is especially important when selecting breeding sires for the artificial insemination network. The purpose of the research was to study the quality indicators of milk of cows bred in the region of breeds (Ayrshire, Holstein, Yaroslavl), and the protein-milk product produced from it as cottage cheese, depending on the influence of the genotype. The research has been carried out in CJSC “Agrofirma “Pakhma” in the Yaroslavl region. The object of research was cows of Ayrshire, Holstein and Yaroslavl breeds. The sample included 99 cows, including 36 animals of Ayrshire breed, 33 Holstein and 30 Yaroslavl breed. A comparative comprehensive evaluation of the dairy productivity of cows of Ayrshire, Holstein and Yaroslavl breeds under the conditions in one herd using DNA testing has been carried out, for the entire productive period of economic use, the realization of the genetic potential has been traced. For the first time in the Yaroslavl region DNA testing of Ayrshire cows was carried out and new data on the polymorphism of the CSN3 and LGB genes in Holstein and Yaroslavl cows were obtained. The association of CSN3, LGB genotypes and complex genotypes with milk productivity and technological properties of milk has been investigated. The yield and quality of cottage cheese from the milk of cows of different breeds in association with CSN3 genotypes have been studied. As a result of studying the quality indicators of milk of cows of different breeds and the protein-milk product produced from it as cottage cheese, depending on the influence of the genotype. It has been found that cows of different breeds and different genotypes had significant differences in the quality of milk and cottage cheese produced from it, which must be taken into account when conducting breeding work with these breeds.

Babukhadiya K.R., Reshetnik E.I. Functional cottage cheese product enriched with non-traditional vegetable components

The article considers the possibility of expanding the range of fermented milk products enriched with natural sources of biologically active substances, which is an urgent task today, as it corresponds to the concept of state policy of the Russian Federation in the field of healthy nutrition. As a solution to this problem, it has proposed to enrich the curd mass as part of the daily diet. Promising plant raw materials of the Far Eastern region, such as Ahnfeltia tobuchinensis, a representative of the genus of red algae growing in the Far Eastern Seas, are used as functional and enriching ingredients; Dahurian larch wood extract – arabinogalactan (Lavitol-arabinogalactan) and peppermint (Méntha piperíta). Grounded ahnfeltia was used in the size of not more than 0,5 mm. On the basis of the analysis of the composition and properties of the applied non-traditional additives, the possibility of enrichment of curd products with dietary fiber and organic iodine from plant components has been substantiated. Optimal ratios of enriching prescription components to the weight of cottage cheese in a finished product are the following: ahnfeltia powder – 1,5%, arabinogalactan – 2,5%, peppermint – 1%. Also, when determining the optimal dosages of the introduced components, it is proposed to replace the prescription amount of sugar with flower honey, which is a natural sweetener and a powerful antioxidant. Organoleptic and physicochemical parameters of the finished samples have been analyzed. As a result of the research the functional curd product one portion (100 g) of which is capable to satisfy daily physiological need of an organism for iodine for 29,32%, in dietary fibers for 12,38% has been developed.

FORMULATION CURD SOUFFLE FOR GLUTEN-FREE NUTRITION

Рост числа больных с алиментарно-зависимыми заболеваниями во многих странах делает необходимым расширение ассортимента продуктов для диетического питания. Исследована возможность применения полисахаридов микробного и растительного происхождения в качестве структурообразователей в рецептуре творожного суфле для безглютенового питания. Предложена замена глютенсодержащего сырья – пшеничной муки на полисахариды (ПС) ксантан и гуаран. Объектом исследования были образцы творожного суфле с внесенным ксантаном или гуараном в количестве 0,3; 0,5; 0,7 и 1,0% от массы сырья взамен пшеничной муки. Контролем служил образец суфле из творога, приготовленного по стандартной рецептуре, без замены пшеничной муки ПС. Установлено, что после выпечки консистенция изделий с ксантаном не соответствовала требованиям, предъявляемым к суфле: оно было плотным и не обладало ярко выраженной характерной пористостью. Наивысшую органолептическую оценку получил образец суфле с содержанием 0,3% гуарана со структурой и вкусом, характерными для контрольного образца. Исследованные физико-химические показатели и пищевая и энергетическая ценность разработанного творожного суфле для безглютенового питания сопоставимы с аналогичными показателями контрольного образца. Рассчитано, что при годовом объеме выработки разработанной продукции 35,3 т срок окупаемости составит 0,33 года при рентабельности 50%. The increase in the number of patients with alimentary-dependent diseases in many countries makes it necessary to expand the range of products for dietary nutrition. The possibility of using polysaccharides of microbial and plant origin as structure-forming agents in the formulation curd souffle for gluten-free nutrition has been investigated. Replacement of gluten-containing raw materials – wheat flour with polysaccharides (PS) xanthan and guaran is proposed. The object of the study was samples of cottage cheese souffle with xanthan or guaran added in the amount of 0,3; 0,5; 0,7 and 1,0% of the mass of raw materials instead of wheat flour. The control was a sample of a souffle made of curd prepared according to a standard formulation, without replacing wheat flour with PS. It was found that after baking, the consistency of products with xanthan did not meet the requirements for the souffle: it was dense and did not have a pronounced characteristic porosity. The highest organoleptic rating was given to a souffle sample containing 0,3% guaran, which had the structure and taste characteristic of the control sample. The studied physical and chemical parameters and the nutritional and energy value of the developed curd souffle for gluten-free nutrition are comparable with similar indicators of the control sample. It is calculated that with an annual output of 3,3 tons of developed products, the payback period will be 0,33 years with a profitability of 50%.
