Abstract
The article describes the possibility of using vegetable raw materials such as pine nuts meal as a protein-vitamin complex in spread technology. Pine nuts are rich with essential amino acids, mono- and polyunsaturated fatty acids, polysaccharides and water-soluble sugars, fat-soluble and water-soluble vitamins, macro and trace elements. It has excellent stabilizing properties in emulsion systems. Also, in article is described technology of spreads made by transformation of a fat mixture. It is justified the choice of the parameters of individual technological operations, in particular, the pine nut meal adds to spread during the homogenization process. For this purpose, dry powder is mixed with pre-pasteurized water, butter or cream in a ratio of 1:2–1:10 at a temperature of 20–40 °C. Mixture is kept at this temperature for 5–20 minutes. Then mixture is cooled to the spread homogenization temperature. Homogenization of the spread is carried out in order to improve the consistency and stability of taste during storage. Spread temperature during loading into the homogenizer should be 11–12 °C in summer and 14–15 °C in winter. Temperature of the spread after homogenization should be 13–15 °C. Optimal dose of cedar nuts meal is determined like 1 % and 3 % by weight of the finished spread. It is described organoleptic, physicochemical and structural-mechanical parameters of the finished product. Spreads containing 1 % and 3 % pine nuts have better heat resistance and moisture distribution. This can be explained by the fact that a small amount of pine nuts does not effects on the structure and texture of spreads. Researches of spread structural indicators have shown that the introduction of more than 3 % of pine nuts has negative influence on it’s structure, in fact, it causes poor moisture distribution and increases the speed of curing, which negatively effects on quality of the finished product. Using of pine nuts in the spread production is appropriate in terms of enrichment of the product with biologically active substances and in terms of expansion of the range of dairy products.
