Effect of dietary fiber on yoghurt quality

The production of yoghurts and yoghurt drinks is one of the fastest growing segments of the dairy industry. The range of this type of dairy products is constantly updated. In the course of the experiments, the use of functional bamboo and apple fibers in the amount of 0.1–1.5 % in the formulation of yogurts made by the thermostatic method based on cow's milk has been studied. According to organoleptic, physicochemical and microbiological parameters, yogurt has been selected with the addition of bamboo fibers at a concentration of 0.3 %. In a sample of this yogurt, compared with the control sample (cow's milk without fibers), the mass fraction of sugar is slightly higher (by 0.1 %), the mass fraction of solids does not differ from the control, and the acidity is 2.5 % less. The amount of lactic acid bacteria of the genus Lactobacillus in the sample with the addition of bamboo fibers at a concentration of 0.3 % is less than in the control, but is within the normal range for this product. In the course of determining the nutritional and energy value, slight changes in the main nutrients in the experimental yogurt sample have been noted in comparison with the initial raw material and control, which caused a slight decrease in calorie content (by 7.49 and 3.61 %, respectively). The high nutritional value of the developed yogurt allows it to be positioned as a functional product. Economic calculations have shown the feasibility of introducing this development into the food industry.

Development of the technology of milk sauce with the addition of guarana

One of the ways to improve the taste characteristics and increase the nutritional value of cooked meat, fish and poultry dishes is to include various sauces in their composition. Traditionally, the composition of sauces includes wheat flour, vegetables, spices. Nowadays powdered plant compositions of polysaccharides (PS), such as locust bean gum and guarana, have gained wide popularity. Based on the organoleptic studies performed, samples of milk sauce with the addition of guarana in concentrations of 0.5 and 1.0 % have been selected, which have been compared with a control sample made using wheat flour. The introduction of 0.5 % guarana into the composition of the milk sauce does not change the level of the mass fraction of fat in the sample, and the addition of 1.0 % guarana has increased the mass fraction of fat by 2.05 times compared to the control. Replacing wheat flour with a polysaccharide in the studied samples with the addition of guarana at concentrations of 0.5 and 1.0 % has reduced the level of mass fraction of solids by 8.3 and 7.9 % and titratable acidity by 3.6 and 5 °T, respectively. According to generally accepted microbiological indicators, prototypes of milk sauce with guarana correspond to regulatory documentation. In the developed sauces, the content of proteins has decreased by 22.19 %, fats – by 2.46 %, carbohydrates – by 54.76 %, which led to a decrease in energy value by an average of 32.16 %. Thus, milk sauce with the addition of guarana can be recommended as a dietary product for preventing obesity, improving lipid metabolism, and lowering cholesterol levels. In the course of determining the economic efficiency of introducing milk sauce with guarana into production, it has been found that the profit amounted to 9628.26 thousand rubles with an annual production capacity of 677.76 tons per year.
