Recently, it was learned from the manufacturer of sodium benzoate that canned fruits and vegetables are canned foods made of fruits, vegetables, (except mushrooms) tomatoes through processing, exhaust, sealing, heating, sterilization, cooling and other processes, including glass bottles, metal cans and soft packaging. According to different processing methods, canned fruit can be divided into canned sugar water fruit, canned syrup fruit, canned jam fruit and canned fruit juice. The main representative products include canned sugar water orange, canned sugar water pineapple and canned yellow peach.

Canned fruits and vegetables are directly imported food. Consumers should pay attention to the following points when purchasing and eating:

1. When buying canned fruits and vegetables, first observe whether the outer packaging is clean and tidy and the handwriting and printing are clear; Secondly, look at the food label, which should indicate the factory name, address, ingredient list, net content, solid content, standard number, quality grade, date and other information. The general material list contains water, white granulated sugar, citric acid, acesulfame, vitamin C, sodium benzoate, etc.

2. For products packaged in glass bottles, observe whether the shape of the contents is complete, whether the soup is clear, and the color should be the inherent color of fruits and vegetables. When choosing products packaged in metal cans, do not buy products with rust caused by corrosion on the outer wall or cover of metal cans.

3. Do not buy products with changes in the shape of the package. When the canned fruits and vegetables are polluted by microorganisms and lose their edible value, the phenomenon of "fat listening" often occurs, that is, the volume of the outer package of the product increases through visual observation. During transportation, the products packed in metal cans are often subject to the collision of objects, and the outer wall is often sunken. The air is very easy to enter, resulting in the deterioration of the contents. The products found in the above situations cannot be eaten.

4. When buying canned fruits and vegetables, you should distinguish between canned sugar water and canned syrup. The concentration of sugar water in canned sugar water is generally about 15%, which is more suitable for direct consumption. The sugar concentration of syrup cans is very high, more than 65%, which is only suitable for food processing. Therefore, consumers should see the concentration of sugar water on the food label, distinguish it, and then buy it.

5. Consumers should try their best to buy products produced by regular enterprises or enterprises with a certain scale in the main production area in reputable shopping malls. When purchasing, carefully check the production date and shelf life, and carefully check the integrity of the outer packaging.

6. The contents of water and sugar in canned fruits and vegetables are very high. After opening the lid, it is easy to cause a large number of microorganisms to reproduce, cause the rancidity of products and lose edible value. It is recommended that consumers eat canned fruits and vegetables at one time after opening them.
