The advantages of tinplate

 No light penetration In addition to triggering food deterioration reactions, light can also cause changes in protein and amino acids. Vitamin C is more easily exposed to light. Tinplate and other food ingredients, resulting in a large loss. According to research analysis shows, the milk of transparent glass bottle, the loss of vitamin C is 14 times higher than the milk of brunet bottle, light also can make milk produce oxidation peculiar smell, and radionuclide, methionine and so on lysis and loss of nutritional value, the impervious light of tinplate can make the retention rate of vitamin C is the highest. Good sealing The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. The comparison of various fruit juice containers showed that the oxygen transmittance of the containers directly affected the Browning of fruit juice and the preservation of vitamin C. The preservation of vitamin C is better in metal cans, glass bottles, aluminum foil and paper boxes with low oxygen transmittance, and iron cans are the best.
