I. Opaqueness

It is well known that light will cause a qualitative reaction in food, in addition to the mutation of proteins and amino acids. The vitamin C in food is more likely to lose a lot of its nutrients when it is exposed to light. According to relevant studies, transparent bottles of milk, the loss of vitamin C than dark bottles of milk up to 14 times, light will cause the milk to produce oxidation and thus odor, so that nucleotides, methionine and other cleavage and loss of nutritional value, impervious to light makes the tin cans in the product's vitamin C preservation rate Z high.

Second, excellent sealing

Packaging containers for air and other volatile gas barrier, the preservation of nutritional composition and sensory quality is very important. From the comparison of various juice packaging containers can prove that the oxygen permeability of the container directly affects the browning of fruit juice and the preservation of vitamin C; low oxygen permeability of metal boxes, glass bottles and aluminum foil gel layer, paper boxes on the preservation of vitamin C is better, which is the best tin can packaging. Third, the reduction of tin

Tin tin tin wall will be filled with the residual oxygen in the container when the reduction effect, so you can reduce the chance of food ingredients are oxidized. Tin reduction, the light-colored fruit, juice flavor and color has a very good preservation effect, so the use of non-coated plain iron box of juice, nutrition preservation than other materials packaged juice better, brown change slightly, longer storage period.

Third, the help of the human body

Due to the electrochemical effect of metal, no inner coating of canned food in storage will have a small amount of iron leaching, in the form of divalent iron in sealed canned food, easily absorbed by the human body, thus iron cans of food and drink is not lost as a source of iron, for tin cans of food to provide more far-reaching significance of nutrition.

Because of these properties, so tin cans provide a closed system in addition to heat, completely isolated from environmental factors, to avoid color food deterioration due to light, oxygen, moisture, food storage stability than other packaging materials, the highest preservation rate of vitamin C, the preservation of nutrients is also the best.
