Embodiment 1
[0028] Raw juice processing technology and products:
[0029] Materials: new apple pear, pectinase, amylase.
[0030] Production process: Weigh 50kg of new pear fruit, remove the damaged and rotten fruit, rinse with clean water, crush and squeeze the juice, heat the squeezed juice to 80-95°C to inactivate the enzyme, the optimum temperature for inactivating the enzyme is 90°C, after deactivating the enzyme, lower it to 45°C, add pectinase and amylase at 0.1‰ and 0.04‰ of the weight of the fruit juice respectively, and keep it in a constant temperature water bath for 60-70 minutes, then test the degradation effect of pectin and starch. The fully degraded fruit juice is filtered with a silicon bath soil filter, and the diatomite is 25 μm in middle soil. After filtration, it is filtered and sterilized with a JM1812-1 roll-type composite membrane filter. The specification of the composite membrane is 0.01 μm, and the working pressure is 0.5Mpa, after sterilization, bottle under a...
Embodiment 2
[0033] Raw juice processing technology and products:
[0034] Materials: new apple pear, pectinase, amylase.
[0035] Production process: after the enzyme inactivation described in Example 1, lower the temperature to 45-48°C, add pectinase and amylase at 0.12‰ and 0.035‰ of the fruit juice weight respectively, and the others are the same as in Example 1.
Embodiment 3
[0037] The pectinase and the amylase of adding 0.11‰ and 0.035‰ of fruit juice weight described in embodiment one respectively, other are the same as embodiment one.
