Pineapple extract solution, preparation method thereof and pineapple drink containing extract solution

Abstract

The invention discloses a pineapple extract solution and a preparation method thereof. The method comprises the following steps of: 1) freezing a pineapple, adding water, pulping and then heating to the temperature of 90-100 DEG C to obtain pineapple pulp; 2) cooling the pineapple pulp, performing acid adjustment, and performing first enzymolysis; 3) performing second enzymolysis after alkali adjustment, and performing high-temperature enzyme killing; 4) performing the acid adjustment again, then performing solid-liquid separation, and collecting supernatant fluid; and 5) performing centrifugal separation and filtration on the supernatant fluid, and concentrating and distilling filtrate to obtain the pineapple extract solution. The method adopts a double-enzyme enzymolysis technology, so that macromolecular sugar and proteins in the pineapple can be fully hydrolyzed into micromolecular nutrient substances so as to be conductive to absorption by a human body. The invention further discloses a pineapple drink containing the pineapple extract solution, and the pineapple drink has the advantages of mellow taste, transparent color and luster and abundant nutrition.
