Canned fruits refer to canned foods made from fresh fruits or frozen or pre-canned fruits. According to the different processing methods, it can be divided into sugar and water, syrup, jam, jelly, fruit juice and so on. CODEX STAN 51-2003 "Guidelines for Canned Medium of Fruits" classifies canned medium of fruits (soup juice), mainly including sugar water, syrup, sugar water and fruit juice mixture, etc.

 

 

 

Qiu Kai, deputy secretary-general of the Canned Technical Committee of the National Food Industry Standardization Technical Committee, told reporters that canned sugar and water and syrup fruits are usually canned with sugar liquor made up of white granulated sugar only. At present, the canned sugar and water standard in China generally stipulates that the concentration of sugar and water is 14%-18%, and the high concentration of sugar can reach more than 22%. Because there are fewer people who eat products with high sugar concentration in our country, the sugar concentration of products seen in our market is mostly between 14% and 18%. In recent years, the food additive industry has developed rapidly, especially the application of food sweeteners in food is more and more. Some enterprises use food sweeteners to partly replace or completely replace sugar, which not only meets people's demand for low-sugar and sugar-free foods, but also reduces the cost of products appropriately. Therefore, when choosing canned food, consumers should read labels carefully and choose suitable products according to their own needs.

 

 

 

For jam and juice cans, Qiu Kai said that jam cans are jam-like or block-like jam products processed by canning technology. Generally, soluble solids are above 65% (refractometer at 20 C) without preservatives, but they must meet commercial aseptic requirements, such as citrus jam, strawberry jam, canned peach jam, etc. The shelf life is usually two years. Canned fruit juice is a kind of fruit juice product processed by canning technology, without adding preservatives, but it must meet the requirements of commercial sterility, such as orange juice, pineapple juice, coconut juice, almond dew canned, etc. The shelf life is generally not less than one year. When choosing this kind of product, consumers can judge whether it is canned food by reading the label ingredient list or inquiring the product standard (execution standard).
