Characteristics and advantages of tinplate
Tinplate canned food, except for a few light-colored fruit and juice cans, mostly use empty cans painted inside to improve the corrosion resistance of the container; due to the electrochemical action of metal, painted canned canned food will have a small amount in storage. The iron is dissolved in the form of ferrous iron in sealed canned food, which is easily absorbed by the human body, and the content is about 1 to 10 ppm. As far as fruit and vegetable products are concerned, the raw material itself does not contain much iron. The iron content of iron cans is calculated as a 350 ml beverage can with an iron content of 5 ppm. Each can can provide 1.75 mg of iron, which is about 18 mg of human daily intake. one-tenth of . If the above fruit and vegetable juice beverage cans are rich in vitamin C, iron will be more easily absorbed, so iron canned food and beverages are a good source of iron, and the significance of providing nutrition to iron canned food is more profound.
Because of these properties, tinplate cans provide a closed system that is completely isolated from environmental factors except heat. Color-avoiding foods are deteriorated by light, oxygen, and moisture, and are not faded by aroma transmission or permeated by environmental odors. The food has better storage stability than other packaging materials, the preservation rate of vitamin C is the highest, and the preservation of nutrients is also the best.
