Processing method of fruit juice

Abstract

The invention relates to a food depth processing technology and especially relates to a processing technology for processing fruits into fruit juice. The method comprises steps of: first checking and accepting raw materials, selecting mature fruits as raw materials and removing fruits with insects and diseases and rotted fruits; and preferably selecting 80% mature fruits as raw materials; second, fragmenting cleaned fruits properly and killing enzyme immediately; third, heating fragmented fruits to 100 DEG C rapidly and maintaining for 5 min; fourth, adding the above treated fruit blocks into a juice extractor to squeeze juice; fifth, carrying out coarse filtration on the extracted juice and centrifuging with a rotating speed of 3000 round / min for 5 min to obtain a normal juice; sixth, mixing well the blended fruit juice and homogenizing in a high pressure homogenizer for one time; seventh, introducing a homogenized material liquid into a vacuum degasser, degassing for 5 min and filling; and eighth, maintaining at 95 DEG C for 5 min to sterilize and cooling fully to obtain a finished product. The fruit juice has good mouthfeel and colour preserving and will not influence health of consumers for long-term drinking. The processing technology has high machining efficiency, and according to tests, the fruit juice produced by the method has an average juice yield higher than 75%.

Description

technical field [0001] The invention relates to a deep processing technology of food, in particular to a processing technology of fruit juice. Background technique [0002] At present, the planting of ginseng fruit, yacon, and lemon fresh fruit has just started in China. In addition, most areas in my country are not suitable for planting ginseng fruit, yacon, and lemon. There is no one in the industry that produces such fruit juice drinks. Therefore, deep-processing The technology is not yet mature. [0003] my country has a population of 1.3 billion, but the sales of fruit juice drinks are relatively low. The per capita annual consumption is less than one kilogram, which is 1 / 10 of the world level and 1 / 40 of developed countries. The industry has a relatively large room for development. [0004] Judging from the fruit juice beverage market, there is still a lot of room for development, and it has been developing rapidly at an annual growth rate of 12% in recent years. Afte...

Problems solved by technology

[0009] The fruit juice processing technology provided by the present invention effectively solves the problem of fruit juice browning, and the fruit juice undergoes two high-temperature treatments, which not only achieves the effect of sterilization, but also increases the freshness period of the fruit juice, so it is not necessary to add Preservatives and preservatives can also guarantee its shelf life, and the juice maintains its natural and fresh taste, color retention is intact, long-term drinking will not affect the health of consumers
