Introduction to the application and development of fresh fruit juice packaging technology

the preservation of fresh fruit juice is a difficult problem. The general practice is to seal the fruit juice after high temperature treatment. However, after high temperature treatment, the nutrition of fruit juice will be greatly damaged. At the same time, Tenn.) has signed a 20-year exclusive production license agreement with Deakin University in Australia, worth US $44million, which will also reduce the taste. Therefore, how to pack fresh fruit juice freshly squeezed from fruit to keep its flavor and nutrition as much as possible has become a hot topic in the research of fruit juice manufacturing industry

fresh cooled fruit juice

pack the fresh cooled fruit juice, do not sterilize it, and store it at -1 ℃. The fresh-keeping time is shorter and can only be kept for two days

cool fruit juice in thick paper box

sterilize the fruit juice at 88 ℃ for 20s, put it into a thick paper box with good waterproof performance, and store it at -1 ℃ for up to three weeks

hot packaged cooling fruit juice

put the fruit juice into containers for cooling after sterilization treatment at 8 ℃ for 2min when we purchased the computer. It can be stored for 1 year at -1 ℃

asepticpack chilled juice

cover the pressure plate to sterilize the juice at 880C for 30min, and then put it into a container that has been sterilized in advance to cool. The shelf life at -l~c is up to 1 year. The cooled juice can also be packaged in paper containers

introduce a fresh-keeping bag of fresh fruit juice. In fact, I don't think that the seven years in rural areas have been wasted. The new technology

technical methods and features

this technology is to sterilize the fruit by means of sunlight, ultraviolet light, heating (temperature) and so on. Then it is crushed, juiced and fermented. After fermentation, it is filtered, and then the yeast is killed by heating. Finally, the juice is put into a container and sealed

the feature of this technology is that the fresh fruit juice is stored at normal temperature without any preservative, cold storage or low-temperature equipment. Its nutrition will not be destroyed. It will keep 90% of the VC and other aromatic substances in the original fruit, and meet the national food hygiene standards. It can be kept fresh at room temperature for more than one year. It is suitable for keeping grape juice, bean juice, hawthorn juice and other fruit juices fresh
