How to identify the quality of canned fruit
Canned fruit food is very convenient to eat. Many people don't know how to identify canned food. Here, the cannery will teach you how to identify the quality of canned fruit food.
1. Observe whether the bottom of the can is bulging. Normal fruit cans have a top clearance requirement of about 0.4CM, depending on the manufacturer's process requirements. In order to ensure that the cans are expanded during the high-temperature sterilization/sterilization process. If the bulge is very serious, it can be judged that there is a product quality problem, which does not meet the requirements of commercial sterility. Some canners have too much content. The first method is to suppress it, and there is no shortage.
2. If the content is too much or the vacuum degree is not enough, you can tap it with a pen, and you can hear two kinds of mixed and crisp sounds. The sound with air or a lot of content is a mixed sound, while the normal sound is very crisp and very crisp. clear. Afraid of making mistakes in judgment, as soon as you take the can and shake it lightly, you will know the content of the can and judge its quality.
3. Press down on the lid of the tank with your hand, if it is easy to go down and there is a sound, it indicates that the vacuum degree is not very good, and there is an expansion tank.
4. When buying canned fruit in the market, first observe the appearance of the can, whether it is rusted or not, and the font is clear, especially when the shelf life is clear.
5. After opening the can, see if there is a black vulcanization phenomenon, and find such a situation on the wall of the tube, which indicates that the can has been contaminated although it meets the requirements of commercial sterility. It is mainly due to the chemical reaction between the soup or the actual ingredients and the tin-plated cans. The manufacturer needs to check the composition of the tinplate with the empty can factory.
