A kind of aseptic preparation process based on aseptic liquid beverage

Abstract

The invention relates to an aseptic preparation process based on aseptic liquid beverages, which includes: sterilizing raw and auxiliary materials by ultraviolet light, and using a negative pressure weighing chamber to weigh and proportion the raw and auxiliary materials in the material bag after sterilization The mixed material is obtained and the mixing tank is cleaned and sterilized online. After cleaning and sterilization, the mixed material is put into the mixing tank for preparation, and the preparation liquid is obtained and transported by sterile compressed air to obtain the reserve liquid. In this process , use the water immersion detection method to carry out the integrity detection of the filter elements of the first sterilizing level filter and the second sterilizing level filter, and according to the test results, re-filter the first stock solution that does not meet the conditions during the test, Adjust the filtration pressure of the second reserve liquid that does not meet the conditions during the test, so that aseptic liquid drinks can be obtained without using preservatives throughout the process, saving resources, maintaining effective finished products of aseptic liquid drinks, and ensuring the safety of sterile liquid drinks There is no loss of nutrients.

Description

technical field [0001] The invention relates to the field of food processing technology, in particular to an aseptic preparation technology based on aseptic liquid beverages. Background technique [0002] With the improvement of people's living standards, aseptic liquid drinks have become an indispensable daily drink for people to pursue a safe and healthy life. Sterility, which means the absence of viable bacteria, is an important concept in biotechnology. Only under the premise that the culture medium, fermentation equipment, etc. are sterile, after the microorganism is inoculated, the pure-bred culture can be realized, and the desired product can be finally obtained. The method of preventing microorganisms from entering the body or object is called aseptic manipulation or aseptic technique. [0003] In order to obtain aseptic liquid drinks, the current preparation process in the industry is to sterilize raw materials and auxiliary materials (such as preservatives) separ...

AI Technical Summary

Problems solved by technology

[0003] In order to obtain aseptic liquid drinks, the current preparation process in the industry is to sterilize the raw materials and auxiliary materials (such as preservatives) separately, and then mix them according to the required ratio in a sterile state, and fill them with filling equipment. The use of preservatives will cause a waste of resources, and will change the effective finished product of aseptic liquid drinks, resulting in the loss of its nutritional content
