A2 milk as an alternative to goat milk in yoghurt production

The article discusses and analyzes the prospects for the use of cow’s milk A2 as an alternative to goat milk in the production of yoghurt. It has been analyzed that goat’s milk is less allergenic than cow’s milk. The genotype of A1 and A2 milk samples was determined using molecular biological analysis of allele recognition by polymerase chain reaction (PCR) in real time. The organoleptic characteristics of yoghurts made from cow’s milk A1, A2, goat’s milk, from a mixture of goat’s and cow’s milk of different genotypes were studied and presented in the work in the form of a profile analysis using the significance coefficients of each individual descriptor (color, smell, taste, appearance and consistency). The physicochemical parameters (protein and fat content) of yoghurts made from cow’s milk A1, A2, goat’s milk, from a mixture of goat’s and cow’s milk of different genotypes were determined. High fat and protein content was found in sample № 3 made from goat milk. The protein content is 3.99 g per 100 g of product, fat – 4.1 g per 100 g of product. Sample No. 2 is made from A2 cow’s milk contains 0.5 g per 100 g of product less protein and 0.6 g per 100 g of product less fat than sample No. 1 made from A1 cow milk. The best result in terms of protein and fat content in the sample of yogurt № 4, made from a mixture of cow and goat milk. This paper presents a comparative analysis of the energy value of yoghurts based on cow’s milk A1, A2, goat’s milk, from a mixture of goat’s and cow’s milk of different genotypes. It should be noted that the highest numerical values of the level of balance in terms of organoleptic indicators and energy value were obtained by samples of yoghurts made from a mixture of cow’s A2 milk and goat’s milk. Studies have shown that yoghurts made from a mixture of goat and cow milk meet the requirements of the standard.
