Embodiment Construction

[0009] In the present invention, first select fresh pineapples that have no deterioration, no damage by diseases and insect pests, and are ripe for 8 to 9 years, and put the selected pineapples into an ultrasonic cleaning machine that has added ozone solution, wherein the ozone concentration is 1mg / l, and the ultrasonic working frequency is 20kHz , the ultrasonic power of each cubic cleaning solution is 300W, and the cleaning time is 3 minutes. The cleaned pineapple is steamed in steam at 100°C for 1.5 minutes, and then the pineapple is cut in half, and the juice is taken out with a filter press. : water = 1:0.8, add water and mix, then press filter to get the juice, the extracted pineapple juice should be treated with compound enzyme enzymolysis in time, first add cellulase enzymolysis treatment, then add pectinase enzymolysis treatment after 30 minutes, the fiber The amount of prime enzyme is 25U / 100ml, the amount of pectinase is 3U / 100ml, pH3.2, time is 38 minutes, temperatu...
