Tips for purchasing canned fruits

When purchasing canned fruits, first observe whether the outer packaging is neat and clean and the writing is clear; secondly, make sure During the shelf life of the product, whether the company's name, factory name, factory address, ingredient list, net content, solid content, standard number, quality grade and other information are marked on the food label.
2. When choosing products packaged in metal cans, do not buy products whose outer walls or lids are rusted due to corrosion. If you choose products packaged in glass bottles, you can observe whether the block shape of the contents is complete and whether there are foreign objects. Some canned fruits often have quality problems such as discoloration during processing or storage and transportation, so it is also necessary to check that the color of the fruit should not brown.
3. Do not buy products whose packaging appearance has changed. When canned fruits are contaminated by microorganisms and lose their original edible value, the "fat listening" phenomenon of the product often occurs, that is, the volume of the outer packaging of the product increases through naked eye observation. Products packaged in tinplate cans are also easily impacted by objects during transportation. The outer wall often appears to be indented, and air can easily enter, causing the contents to go rancid and deteriorate. Products found to be in the above situation cannot be eaten.
4. When purchasing canned fruits, you should distinguish between canned sugar water and canned syrup. The sugar water concentration of canned sugar water is generally around 15, which is more suitable for direct consumption. The concentration of sugar water in syrup cans is very high, above 65, and is only suitable for food processing. Therefore, consumers should read the sugar water concentration content clearly on the food labels when purchasing, and distinguish them before purchasing.
5. Consumers should try their best to purchase on large e-commerce platforms or large shopping malls. For example, Jingyu small black canned fruit cans are good. When purchasing, you should carefully check the production date, shelf life, and the integrity of the outer packaging.
6. Fruits in canned fruits are susceptible to deterioration due to the influence of moisture and sugar. After opening the lid, it is easy to cause a large number of microorganisms to multiply, causing the product to go rancid and lose its edible value. It is recommended that consumers try to eat it all at once after opening the lid. If you can't finish it, you can store it in the refrigerator, but it shouldn't be stored for too long.
