Annotation
Currently protein products containing irreplaceable amino acids are of great importance for human nutrition. The article deals with the peculiarities for IRconvective drying of a protein diary product. The choice of drying mode is substantiated on the basis of drying curves; dependencies of water activity on drying time; microbiological and organoleptic indictors; and the content of amino acids. The product is proved to be dried up to the water ratio of 23.2 when water activity (Аw) in the product decreases to 0.83 and Staphilococcus aureus bacteria and a number of other pathogenic microorganisms are not able to grow in the media with the above value of water activity and lower, which is confirmed by the analysis of microbiological characteristics. Then, the results of the research can be used when developing technology for a dry protein-based dairy product.
