Determining the influence of hemp seed protein on the quality indicators of cheese product and the content of nutrients in it

Abstract

The growing tendency to produce cheese from animal and plant ingredients has led to the diversification of cheese-making technologies and the search for new cheese suitable raw materials. The research object is the technology of cheeses made from combined raw materials: cow's milk and hemp seed proteins. Subjects of research: organoleptic and physical-chemical indicators of cheese product samples; amino acid composition of cheese product samples. The inclusion of vegetable raw materials in the cheese technology affects the technical properties of milk-plant mixtures, in particular, their syrupy properties, and the quality of the finished cheese product. Samples of cheeses were produced according to the traditional technology of Cachotta type cheese. The conducted research established that the proteins of hemp seeds affect the sensory characteristics of cheese. Increasing the content of hemp protein in recipes leads to the appearance of a brown-green color of the cheese product. The taste and smell acquire a characteristic shade of hemp. When vegetable proteins are used in the recipe of cheese, the yield of the finished product increases by 0.3...23.5 %. In experimental samples, the content of fat (by 0.3...2.2 %) and protein (by 1.75...10.4 %) increases. Hemp seed protein balances the amino acid profile in finished cheese. The total content of amino acids in cheese samples was as follows: H10 – 8.25, H15 – 8.35, H20 – 8.44, and H25 – 8.53 mg/g of protein, which is relatively higher than in the control sample H0 – 8.08 mg/g of protein. Taking into account the results of the sensory analysis of the expert commission and the balanced biological profile, the recommended concentration of hemp seed protein in the milk-vegetable mixture is 20 %, which guarantees the acceptable quality of the product. The obtained results are of practical importance, since it can be taken into account that the combination of raw materials of plant and animal origin expands the assortment, increases the raw material base and the output of cheese, and therefore, the profitability of production.
