Manufacturing of curd products of increased biological value for the elderly from dried components

Abstract

Background. In recent years, the number of elderly people has increased, and the diseases that arise in old age are associated, amongst other factors, with malnutrition. In the elderly, the need for primary nutrients and energy changes, so the development of food products intended for this particular group of people is becom- ing increasingly important. The purpose of this research is to work out the composition of and technology for producing low-fat curd products from raw milk and vegetable components. The developed products can be used for their gerodietetic properties, because nutritional and energy needs in the elderly were taken into account when designing the product. The curd product was manufactured from skimmed dried milk (SDM), soy isolate protein (SIP) and spelt grain.

Material and methods. Optimal conditions for the recombination of SIP were determined. The influence of mass fraction of SIP on the properties of the clot and the end product was studied. The degree of dispersion of the grain component was determined, from the organoleptic evaluation of samples of the mixture, and the optimum method of addition was chosen. The method of adding cooked spelt into the clot after pressing was chosen. Harrington’s generalized desirability function was used for the calculation of the optimum mass frac- tion of the grain component in the end product.

Results. The formulation and technology for a curd product based on dry ingredients were determined. The amino acid composition and content of essential components in the developed product were determined, and the biological and nutritional value were calculated.

Conclusions. The use of dry ingredients for the production of a curd product makes it possible to manufac- ture the product in the absence of raw milk. The formulation of the product is designed taking into account the needs of the body in old age. The incorporation of spelt increases the biological value of the curd product to 81.5%.
