Embodiment 1
[0030] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 3.5, and then add 0.5% of the aqueous solution. Gelase, placed in a constant temperature water bath for enzymolysis, the temperature of the water bath is set at 45 ° C, stirring once every 10 minutes during the enzymolysis process, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 5.8, add neutral protease accounting for 0.5% of the aqueous solution mass ratio, set the constant temperature water bath to 45°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes t...
Embodiment 2
[0033] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 3.8, and then add 1.0% of the aqueous solution. Gelase, placed in a constant temperature water bath for enzymolysis, the temperature of the water bath is set at 48 ° C, stirring once every 10 minutes during the enzymolysis process, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 6.5, add neutral protease accounting for 1.0% of the aqueous solution mass ratio, set the constant temperature water bath to 48°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes t...
Embodiment 3
[0036] Squeeze fresh apricot juice, weigh 1 kg of apricot solid-liquid mixture, add 10 kg of distilled water, soak for 60 minutes, add acid-base buffer solution, adjust the pH value of the aqueous solution to 4.0, and then add 1.5% of the aqueous solution. Gelase is placed in a constant temperature water bath for enzymolysis. The temperature of the water bath is set at 50°C. During the enzymolysis process, stir once every 10 minutes, stirring for 5 minutes each time, to ensure that the pectinase can be fully dispersed in the apricot granules, and the apricot pulp The pectin in the medium is continuously enzymatically hydrolyzed, and the enzymatic hydrolysis time is 2h. Then add an acid-base buffer solution to adjust the pH value of the solution, adjust the pH value to 7.0, add neutral protease accounting for 1.5% of the aqueous solution mass ratio, set the constant temperature water bath to 50°C, stir once every 10min during the enzymolysis process, and Stir for 5 minutes to e...
