Embodiment 1
[0010] The pectinase activity is 60,000 units, the cellulase activity is 100,000 units, and the compound enzyme is composed according to the fact that the cellulase accounts for 20% of the total enzyme amount. The addition amount of compound enzyme in the production is 160 grams / ton of raw material. The production process conditions are as follows: the treatment temperature is 35° C., the heat preservation is 25 minutes, and the pH of the pineapple juice is 3.5. The juice yield of the produced pineapple juice is 71.9%, which is 6.9% higher than that without enzyme treatment.
Embodiment 2
[0012] The pectinase activity is 90,000 units, the cellulase activity is 130,000 units, and the compound enzyme is composed according to the fact that the cellulase accounts for 25% of the total enzyme amount. The addition amount of compound enzyme in production is 180 grams / ton of raw material. The production process conditions are as follows: the treatment temperature is 45° C., the heat preservation is 30 minutes, and the pH of the pineapple juice is 4.5. The yield of pineapple juice reaches 73.4%, which is 8.4% higher than that without enzyme treatment.
Embodiment 3
[0014] The pectinase activity is 120,000 units, the cellulase activity is 150,000 units, and the compound enzyme is composed according to the fact that the cellulase accounts for 35% of the total enzyme amount. The addition amount of compound enzyme in the production is 170 grams / ton of raw material. The production process conditions are as follows: the treatment temperature is 50° C., the temperature is kept for 20 minutes, and the pH of the pineapple juice is 4.0. The yield of pineapple juice reaches 74.2%, which is 9.2% higher than that without enzyme treatment.
