Development of canned fruit and vegetable containers and selection methods of canned fruit and vegetable
Now, the pace of people's life is accelerating. Especially for lunch, people will choose some fast food such as canned fruits and vegetables. In this context, canned food has also ushered in a faster development period. This huge market also gave birth to a huge demand for canned fruit and vegetable containers.
In the past, canned food was mainly packed in canned fruit and vegetable containers with glass cans and tinplate lids. This kind of packing is still very popular in the market. However, with the changes of the times. People's requirements for canned food bottles are constantly changing.
On the one hand, this kind of canned food bottle in glass will be very heavy, which is inconvenient for people to carry when they go out or travel in the wild. We all know that canned food is often used by people when they go out. On the other hand, tin cans are very tight. But it is inconvenient to open, especially for women with little strength.
Now the plastic cans and canned food bottles on the market are made of pet, which is very portable. At the same time, due to the combination of the easy pull cover and the outer cover, it is more convenient to open. It should be said that more and more canned food bottles will be in the form of plastic cans in the future.
In short, the market for canned fruit and vegetable containers is very large, and the demand is constantly changing. Therefore, this kind of packaging requires our merchants to have more research and observation on the market.
Three points for attention in selecting canned fruits and vegetables:
1. Select famous brands for canned fruit and vegetable containers:
Cans produced by well-known enterprises have very standardized procedures from raw materials to processing, and there are no problems in safety, hygiene and nutrition. On the contrary, in order to make huge profits, those small canneries use unqualified raw materials and lack the basic knowledge and technology of canning. Therefore, they will violate the standards and add preservatives, pigments and even other harmful additives.
2. Look carefully at the packaging of canned fruit and vegetable containers:
Not familiar with canned brands, worried about not distinguishing defective products? No problem. This is a simple way to distinguish cans by observing the outer packaging of cans. First, check whether the outer package is clean and tidy and whether the handwriting is printed clearly. In addition, the label of canned food produced by regular manufacturers shall indicate the product name, factory name, address, ingredient list, net content, solid content, executive standard code, quality grade, shelf life, etc. Then, don't forget to look at the production date and select the products within the warranty period.
3. Carefully distinguish the quality of canned fruit and vegetable containers:
Next, check the quality of canned food itself. Canned fish and meat: most of these cans are packed in tinplate. Because the inside of a good can is vacuum, the top or bottom of the can should be flat or concave. But for those cans with leaky sealing or improper sterilization, bacteria still breed in the cans, which will produce gas, so the top or bottom of the cans will bulge, so the cans can no longer be eaten. Canned vegetables and fruits: most of these cans are packed in glass bottles, and the contents can be seen. A good can should have even contents and clear and transparent soup. But the contents of bad cans vary in size, and the color of the soup will be much heavier.
