Features of Iron Boxes
I. Opaqueness
It is well known that light causes mutations in proteins and amino acids, in addition to qualitative reactions in food. The vitamin C in food is more likely to lose a lot of its nutrients by the action of 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 highest rate of preservation of vitamin C products.
II. Excellent sealing
<Packaging containers are very important for the preservation of nutrient content and organoleptic quality by blocking air and other volatile gases. 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 iron boxes, glass bottles and aluminum foil gel layer, paper boxes on the preservation of vitamin C is better, which is the best iron can packaging. Third, the reduction of tin
The tin on the inside of the tinplate will have a reducing effect with the oxygen remaining in the container during filling, thus reducing the chance of the food ingredients being oxidized. Tin reduction effect, the flavor and color of light-colored fruits, fruit juice has a good preservation effect, and thus the use of non-coated plain iron tin boxes of juice, nutrition preservation than other materials packaged juice better, brown change slight, longer storage period.
IV. style="font-size: 16px;"> Due to the electrochemical effect of metal, there is 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 body, thus iron canned food and drink is not lost as one of the sources of iron, for the tin can food to provide nutrition The significance is more far-reaching.
Because of these properties, tin cans provide a closed system completely isolated from environmental factors except heat, avoiding color food deterioration due to light, oxygen, moisture, food storage stability is better than other packaging materials, the highest preservation rate of vitamin C, the preservation of nutrients is also the best.
