Разработка хлебобулочных изделий нутриентно-адаптированных для питания спортсменов-легкоатлетов

Abstract

Proper nutrition of an athlete is an important component of the effectiveness of sports results. An athlete’s daily diet should cover his increased nutrient needs due to heavy physical activity. The purpose of the research was to develop bakery products that were nutrient-adapted to the nutritional requirements of athletes using the example of track and field athletes. The recipe for the new product included wheat flour, oat flour, micellar casein, flaxseed oil, date syrup, and crushed walnut kernels. A study of the influence of new ingredients on the quality of semi-finished products and finished products showed that the addition of oat flour and casein slightly increased the moisture and acidity of the finished products, but the indicators remained within the limits defined by the regulatory documentation for bakery products made from wheat flour. With an increase in the dosage of oatmeal and casein, the products acquired a slight taste of oatmeal; casein had no effect on taste. A new type of bakery product is characterized by good organoleptic and physicochemical quality indicators and has increased nutritional value. Consumption of 100 g of the developed “Fitbulka” bakery product allows you to satisfy the daily need for biologically complete protein by 8.9%, carbohydrates by 5.3%, fat by 7.2%, including polyunsaturated fatty acids of the omega-3 family by 39.6% and omega-6 by 5.4%. The degree of satisfaction of the daily requirement for minerals increases in comparison with the control sample and amounts to 16.0% for calcium, 13.5% for phosphorus, 17.4% for magnesium, 7.4% for potassium, and 7.5% for iron. Analysis of amino acid score calculations showed that the biological value of the protein fraction of the test sample was 17.6% higher compared to the control. The developed “Fitbulka” bakery product can be recommended for inclusion in the diet of athletes as an additional source of polyunsaturated fatty acids, dietary fiber, protein, calcium and magnesium in the diet.
