Where is the tinplate box packaging?
At present, the packaging material in the world is none other than tinplate boxes. Why? Because it has the following three characteristics:
1. Excellent sealing
The barrier properties of packaging containers to air and other volatile gases are very important for the retention of nutrient content and sensory quality. Comparison of various juice packaging containers confirmed that the oxygen transmission rate of the container directly affects the browning of the juice and the retention of vitamin C; metal cans, glass bottles, and aluminum foil glue layers and cartons with low oxygen transmission rate retain vitamin C. Better, in the meantime, tinplate is the best choice.
2. 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 the food components being oxidized. The reduction effect of tin has a good retention effect on the flavor and color of light-colored fruits and juices. Therefore, the juice cans packed with unpainted iron cans retain nutrients better than those packed with other packaging materials, and the browning changes slightly. , the tolerance of flavor quality is better, and the shelf life is extended.
In addition to causing the deterioration of food, light can also cause changes in proteins and amino acids. And vitamin C is more easily exposed to light to make it interact with other food components, resulting in a lot of loss. According to research and analysis, the loss of vitamin C of milk in transparent glass bottles is 14 times higher than that of milk in dark bottles. Light will also cause oxidative odors in milk, and the cracking of radionuclides and methionine will lead to loss of nutrient value. The opaqueness of the tinplate makes the vitamin C retention rate very high.
