In addition to the deterioration of food, the customized light will also cause changes in protein and amino acids. Vitamin C is more likely to be exposed to light and other food ingredients, resulting in a large amount of loss. According to research and analysis, the loss of vitamin C in milk in transparent glass bottles is 14 times higher than that in dark bottles. Light will also cause oxidation and peculiar smell of milk, and the loss of nutritional value due to cracking of nuclides and methionine. The opacity of tinplate cans makes the preservation rate of vitamin C the highest.

The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. Comparison of various fruit juice packaging containers proves that the oxygen transmission rate of the container directly affects the browning of fruit juice and the preservation of vitamin C. Metal cans, glass bottles, aluminum foil glue layers and cartons with low oxygen transmission rate have better preservation of vitamin C, of which iron cans are the best.
reduction of tin
The tin on the inner wall of the tinplate will interact with the oxygen remaining in the container during filling, reducing the chance of oxidation of food ingredients. The reduction effect of tin has a good preservation effect on the flavor and color of light-colored fruits and fruit juices. Therefore, the fruit juice cans filled with unpainted iron are better than those filled with other packaging materials. The brown change is slight, the acceptance of flavor quality is better, and the storage period is thus prolonged.
