Tin plate, chromium iron (tin) of the features and advantages:

1,opacity

Light XIAN addition to deterioration of food caused reaction, we will also lead to changes in protein and amino acids. And vitamin C by exposure to light industry spans more easily with other food ingredients to the role, resulting in great loss. According to the research analysis, transparent glass bottled milk, vitamin C loss than bottled milk dark high 14 times, light will also produce oxidation of milk odor, and radionuclides, such as cracking and loss of methionine nutritional value, opaque tin cans make the highest vitamin C preservation.

2, good sealing containers of air and other volatile gas barrier property of the nutritional composition and sensory quality of preservation is very important. Prove more fruit juice containers, container oxygen transmission rate directly affect the browning of fruit juices and vitamin C preservation; oxygen through the low metal cans, glass bottles and plastic laminated aluminum foil, paper on the preservation of vitamin C well, among which the best cans.

3, the reduction of tin tin tin wall with filling containers when the residual oxygen in the role, reducing the chance of food ingredients to be oxidized. Tin reduction, on pale fruit, fruit juice has a good flavor and color preservation, and therefore do not use canned fruit juice cans painted iron than other packaging materials nutrient loading can save the better the juice, brown minor changes, acceptance of good flavor quality, storage period was extended.
