Problems solved by technology

At the same time, the electric field will also change the charge distribution near the cell membrane, resulting in membrane dysfunction, disturbing and destroying the normal metabolic function of the cell, inhibiting the growth of microbial cells, and even stopping growth or causing them to die.

Abstract

The invention relates to a preparing method for pomegranate juice; the method comprises the following steps that a fresh pomegranate is soaked by disinfecting solution, soaked and washed by ultrasonic wave and clear water and then washed by clear water; grains of the pomegranate are peeled after being cut, and the pomegranate juice is squeezed out by beating; a method adopting the combination of vacuum degassing and antioxidant is used for degassing; pectin of the pomegranate juice is hydrolyzed by adding pectinase; diatomaceous earth is used for removing suspended matters; colloidal particles, microorganisms and enzymes are removed by ultrafiltration; the ingredients are regulated; a method of riadiationsterilization is used for sterilizing, and then sterile filling and covering are carried out, thus preparing the pomegranate juice. The highest temperature of processing is less than 50 DEG C in the whole process of production of the pomegranate juice, thus keeping the color, flavor, nutritive value and functional ingredients of fresh pomegranate extracted juice furthest, leading the products to have longer guarantee period and realizing industrial production at the same time.

Description

technical field [0001] The invention relates to a preparation method of pomegranate raw juice. The biggest feature of the method is that the content of the pomegranate raw juice is greater than or equal to 95%. The integrated application of enzyme, aseptic filling and microwave low-temperature sterilization technology avoids the high-temperature treatment in the production of pomegranate juice, and can maintain the color, flavor, nutritional value and functional components of pomegranate juice to the greatest extent. Background technique [0002] Pomegranate (Punicagranatum L.) is a plant of the Pomegranate family Pomegranate, native to Central Asia in the Persian Himalayas, that is, Iran, Afghanistan and other countries now. Introduced to my country via the Silk Road. Pomegranate fruit is bright in color, crystal-clear in grain, rich in nutrition, and its sweet and sour taste is loved by people. Pomegranate fruit is rich in carbohydrates, proteins, various amino acids, tra...
