Embodiment 1

[0033] Using fresh wolfberry as raw material, pick out impurities such as leaves, sepals, fruit branches, insect fruits, rotten fruits and earth and stones. Clean the dust or dirt on the surface of wolfberry with clean water. Adding 0.1% iso-Vc-Na and 0.1% citric acid as a color-protecting agent, performing crushing and beating to obtain wolfberry pulp. Then the wolfberry is pumped down into the ultrasonic-promoted compound enzymolysis tank. Set the ultrasonic frequency to 20kHz, the power to 150W, and turn on the ultrasonic device. Add pectinase, protease and cellulase compound enzyme preparation, the amount of enzyme added is 0.08%, the enzymolysis temperature is 45°C, and the enzymolysis time is 40min. After the enzymatic hydrolysis, the feed liquid is pumped into the plate-and-frame filter, and the pore size of the filter cloth is 200 mesh. Afterwards, the filtrate was pumped into an ultrasonic enhanced membrane separation device, the molecular weight cut-off of the mem...

Embodiment 2

[0035]Dried wolfberry is used as raw material to remove impurities such as mildew, browning, insect-eaten fruit, sand, soil clods, and straw. Clean the dust or dirt on the surface of wolfberry with clean water. After removing impurities, soak the wolfberry in 5 times hot water (65°C) for 30 minutes or in cold water for 2.5 hours. Add color-protecting agent iso-Vc-Na and 0.1% citric acid according to 0.1% (m / V) of the soaking liquid. Dissolve the color-protecting agent completely with a small amount of water first, pour it into the soaking liquid, and stir evenly. The soaked wolfberry is crushed and beaten into a crusher to obtain wolfberry pulp. Then the wolfberry is pumped down into the ultrasonic-promoted compound enzymolysis tank. Set the ultrasonic frequency to 40kHz, the power to 150W, and turn on the ultrasonic device. Add pectinase, protease and cellulase compound enzyme preparation, the amount of enzyme added is 0.07%, the enzymolysis temperature is 50°C, and the e...

Embodiment 3

[0037] Using wolfberry pulp as raw material, it is pumped into an ultrasonic-promoted compound enzymatic hydrolysis tank. Set the ultrasonic frequency to 20kHz, the power to 200W, and turn on the ultrasonic device. Add pectinase, protease and cellulase compound enzyme preparation, the amount of enzyme added is 0.09%, the enzymolysis temperature is 50°C, and the enzymolysis time is 50min. After the enzymatic hydrolysis, the feed liquid is pumped into the plate and frame filter, and the pore size of the filter cloth is 280 mesh. Afterwards, the filtrate is pumped into an ultrasonically enhanced membrane separation device, the molecular weight cut-off of the membrane is 100,000 Dalton, the ultrasonic frequency is controlled at 40kHz, and the power is 300W. This device further removes the substances that cause the turbidity of the liquid wolfberry, and then bottle the membrane permeated liquid, sterilize at 85°C for 30 minutes, and the finished product is finished after cooling d...

Abstract

The invention discloses a production method of liquid medlar. Firstly, medlar pulp is prepared, and then liquid medlar is prepared according to the following technical steps: facilitating composite hydrolysis by ultrasonic wave, filtering, or centrifugal separating, strengthening membrane separation by ultrasonic wave, filling and sterilizing, wherein, in the process of facilitating composite enzymolysis by ultrasonic wave, ultrasonic frequency is 20 to 80 kHz, and power is 50 to 300 W, and complex enzyme which is adopted is the compound of 1 part by weight of pectase, 1.5 parts by weight of proteinase and 2.5 parts by weight of cellulase; enzyme adding amount is 0.01 to 0.15% of the total material quantity, enzymolysis temperature is 40 to 65 DEG C, and enzymolysis time is from 15 to 120 minutes. In the hydrolytic process of complex enzyme, the production method of liquid medlar is promoted by ultrasonic technology, which shortens enzymolysis reaction time for 50% and reduces enzyme adding amount by 20%, so that the production method can obviously improve enzymolysis efficiency and lower production cost.

Description

technical field [0001] The invention relates to the field of food and beverage processing, and belongs to a production method of beverages, in particular to a production method of liquid wolfberry. Background technique [0002] Lycium barbarum contains a variety of nutrients, which are rich in nutritional value and special health care function. Lycium barbarum contains polysaccharides, betaine, carotenoids, vitamins C, K, Na, Ca, Mg, Cu, Fe, Mn , Zn, P and other components.
