How to choose a good candy iron box

 

A good candy iron box is not measured by its exquisite shape. Its quality is qualified iron box. We can use it two times, when we have done it. So, how can we judge the quality of candy iron box?

 

When we see it for the first time, we will have an objective judgement on the box. At the first sight, we can see that the candy iron box surface and box surface reflect the information of design, printing, bar code and specifications. These information is not randomly placed, there are certain random printing rules, and it is not qualified on the surface.

 

Thirdly, see if the surface of the box has been scratched or marked with the appearance quality, and whether the printed surface is blurred or misplaced. The front surface of the product is directly placed in front of the eyes and directly placed underneath. In addition to seeing the main view box, you can also see the inner surface, side, bottom and so on. If there is no such problem, then you choose a perfect iron box with qualified design and printing process.

 

Characteristic

 

Opaque

 

In addition to causing food deterioration, lines also cause changes in protein and amino acids. Vitamin C is more easily irradiated by light than other food ingredients, resulting in a great loss. According to research and analysis, the loss of vitamin C in transparent glass bottled milk is 14 times higher than that in dark bottled milk. Light also causes oxidative odor of milk, and the nutritive value of milk is lost by the cracking of nuclides and methionine. The opacity of tin tins makes the preservation rate of vitamin C the highest.

 

Good sealing performance

 

The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. Comparing various kinds of fruit juice packaging containers, it is proved that the oxygen permeability of the containers directly affects the browning of fruit juice and the preservation of vitamin C. The metal cans, glass bottles, aluminum foil laminates and cartons with low oxygen permeability have better preservation of vitamin C, among which iron cans are the best.

 

Reduction of tin

 

Tin on the inner wall of tinplate acts on oxygen remaining in the container during filling to reduce the chance of oxidation of food ingredients. The reduction of tin has a good preservation effect on the flavor and color of light fruit and juice. Therefore, the fruit juice cans without painted iron have better nutritional preservation, slight browning change, better acceptance of flavor quality and longer storage period than those with other packaging materials.
