[Possibility of fortifying milk nutrient mixtures for children with lactoglobulin against E. coli and Proteus].
Sweet milk nutrient mixtures, biologically active additives (BAA) and lactic acid ferments, intended for child nutrition, were enriched with the immune preparation lactoglobulin against E. coli and Proteus. Serological and immunochemical investigations of hemagglutinating activity and other characteristics of lactoglobulin in the enriched milk mixtures and BAA evidenced that the preparation retained its full value during the technological process and in the period of storage. No signs of lactoglobulin degradation during the production of a test batch of the milk mixture and BAA were detected, and a high hemagglutinating activity with respect to enteropathogenic E. coli and Proteus was recorded. This permitted the author to recommend the lactoglobulin-enriched sweet mixtures for prevention of acute intestinal infections and dysbacteriosis in young children. The in vitro study of the lactoglobulin interaction with pure cultures of lactobacillus and bifidobacteria showed its inertness to eubacteria. Four strains studied retained their growth and acid-forming properties after combined incubation with lactoglobulin and did not inhibit its activity. A conclusion has been made on the possibility of enrichment of lactic acid products, intended for child nutrition, with lactoglobulin against E. coli and Proteus.
