The possibility of obtaining dietary supplements based on chitin-mineral precipitates enriched with peptides by granulation in fluidized bed was studied. The dietary supplement is designed to correct mineral-deficient conditions and insufficiency of dietary fiber in the human diet. The objects of the study were products obtained during the complex processing of waste from the cutting of the northern shrimp (Pandalus borealis) by the electrochemical method – chitin-mineral complex and highly hydrolyzed protein product. The physicochemical properties of chitin-mineral precipitate and protein hydrolyzate have been studied. It has been established that peptides obtained from shrimp cutting waste are a promisingbinder for granulation of mineral precipitate, providing a granulate with a high degree of disintegration (not exceeding 7 min)and improved flowability (more than 8 g/s). It is also shown that the peptides enrich the resulting dietary supplement with essential amino acids. It was found that with an increase in the consumption of the binder, an improvement in the technologicalcharacteristics of the granules is observed (a decrease in bulk density and an increase in flowability), however, when the consumption of the binder exceeds 0.3 mg/g, the formation of a slurry-like mass preventing the formation of granules is observed. The effect of granulation regimes on the amino acid composition of granulated dietary supplements was studied. The finished form of dietary supplement in the form of granules was obtained.
