23 Jul Preparation method of abelmoschs esculentus water-soluble polysaccharide spray-dried powder
Abstract
The invention belongs to the technical field of functional foodstuff engineering, and relates to a preparation method of abelmoschs esculentus water-soluble polysaccharide spray-dried powder. The method comprises steps that: water is added to an abelmoschs esculentus raw material, and the mixture is crushed by using a tissue crusher; compound enzyme is added to the abelmoschs esculentus crushed solution, and the solution is extracted; under an appropriate condition, the solution is processed through enzymolysis extraction; large-particle residues in the extract obtained by enzymolysis extraction are removed by centrifugation with a rotary rate of 4000r/min; the obtained extract is processed through vacuum filtration, such that an abelmoschs esculentus polysaccharide aqueous solution is obtained; maltodextrin is added to the abelmoschs esculentus polysaccharide aqueous solution, wherein the added amount of maltodextrin takes 10%-35% of the mass of dry substances of the abelmoschs esculentus polysaccharide aqueous solution; after maltodextrin is added, high-pressure homogenization is carried out under a homogenization pressure of 16-25MP, and homogenization circulation is carried out for 4-10 times; the homogenized solution is spray-dried with an intake air temperature of 160-200 DEG C and an discharged air temperature of 80-100 DEG C, such that the abelmoschs esculentus polysaccharide dry powder is obtained. According to the invention, utilization rate of abelmoschs esculentus is high, and the dissolubility of the soluble polysaccharide in water is high.
