Study of Chemical and Mineral Composition of New Sour Milk Bio-product with Sapropel Powder

In this paper the results of chemical and mineral composition of new sour milk bio-product with sapropel powder are presented. Sapropel in powder form added to the formulation of sour milk of 1.5% of total mass. Sapropel is characterized by high percent of mineral elements concentration (50.97%), particularly it is rich in manganese 316.0 mg/kg, calcium 148.0 mg/kg (in the form of calcium carbonate), zinc 59.7 mg/kg, copper 24.1 mg/kg. In new sour milk bio-product the protein content was significantly higher (20.95%) than in control sample (18.40%) with decreasing of moisture content to 76.0-76.3% than in control sample 79.50%. Addition of 1.5% of plant sapropel increases the nutritive value of final product up to 15.3 kcal or 16.4% because of high content of protein and fat.
