Development of the composition and technology of dry drinks based on whey

Abstract

Dairy and other food industries use whey in the production of various food products. The analysis of the composition of the ingredients used shows that dry demineralized whey is widely used for the production of specialized food products, which is explained by its high organoleptic characteristics, guaranteed quality and safety indicators. The paper considers the possibility of using dry demineralized whey when creating dry drinks for baby food. The results of organoleptic and physico-chemical studies prove the feasibility of using dry juices and plant extracts when creating the composition and formulations of specialized products. The technology of these drinks involves the stage of dry mixing of the components used. It should be noted that poor-quality mixing of micro- and macrocomponents that are heterogeneous in structure and dry matter is the cause of a decrease in the quality of the finished product. To assess the effectiveness of mixing, studies of the ingredients used in the formulation were carried out in terms of indicators: mass fraction of moisture and particle size. Mixing efficiency was evaluated by determining the key component (vitamin C) in the sample and the duration of mixing. Mixing was considered effective if the vitamin C content in each of the five samples was 12.2–14.9 mg. The results of studies of the mixing process show that the effectiveness depends on the set of prescription ingredients and the dispersion of each of them. The results obtained are applicable for the tested conditions of the experiment: a fixed frequency of rotation of the mixer container, the accepted scheme for loading ingredients, the completeness of the useful volume of the container, recipe variation.
