The gist of this article boils down to the effect of pretreatment of sea buckthorn meal by acid hydrolysis with mineral and organic acids in a concentration of 5% to 20% and enzymolysis by commercial enzyme preparations exhibiting various types of activity with respect to polysaccharides and their multienzyme compositions on the yield and qualitative composition of bioflavonoids. It is shown that the pretreatment of defatted sea buckthorn meal, depending on the method and type of hydrolyzing agent, not only increases the yield of bioflavnoids by 13-15%, but also leads to a change in their composition. It was found that pretreatment with enzyme preparations reduces the likelihood of destruction of the native structure of chemically labile bioflavonoids and hydrolysis of glycosidic bonds with a slight decrease in the efficiency of the process: by 0.1% relative to acid hydrolysis.
