Investigation of the effect of amaranth flour and the protein base of the emulsion gel on the quality of custard cream

The article presents the results of research on the development of custard technology using amaranth flour, starch complex, sunflower oil and protein-polysaccharide mixture (BPS). To enrich the custard, instead of butter, sunflower oil was introduced, which is a source of vitamin E and essential fatty acids (linoleic and linolenic), does not contain cholesterol, and also serves as a source of energy and plastic material for humans. Soy protein isolate and dry whey were intended as a protein in BPS, and sodium alginate, gum arabic and pectin were intended as polysaccharides. On the basis of physical and chemical studies, the optimal combinations of polysaccharides, the percentage of amaranth flour and starch in the cream have been established. It was found that soy-based protein has better physicochemical and organoleptic characteristics in comparison with whey. Research results show that encapsulation in BPS improves the structure of the cream, reduces the density and cost of the product. Custard recipes have been developed based on soy protein isolate and whey powder, with the addition of vegetable oil and amaranth flour. The use of encapsulation allows you to enrich the product with useful oils and dietary fiber. A functional product has been obtained, without the addition of dairy products and wheat flour.
