Can can be a lot of friends of the most love, especially in the hot summer day, a variety of canned fruit canned fruit is a lot of friends with the summer, seeing these incomparable fruit imprisoned in the canned, really want to run past the lid to "save" them. I have a friend who sees a can in his hand every so often that he has no appetite to eat instead.

But for a long time, there have been three impressions of canned products in our country: first, canned food can remain unchanged for a long time, and preservatives must be added; second, the nutritional value of canned food will decline during the process of sterilization and storage at high temperature; and third, the safety quality of canned food is difficult to guarantee. So what is the truth?

In fact, preservatives are the biggest misconception about canned food.  Cans can be preserved for a long time without deterioration, thanks entirely to sealed containers and strict sterilization, and has nothing to do with preservatives. As early as 150 years ago, Pasteur, a French scientist, found that bacteria, mold and yeast can reproduce in a large amount in food, and boiling food can kill bacteria and put food in a closed bottle and can be preserved for a long time.

Nowadays, the processing of canned food is widely applied in pasteurization, sterilizing strictly, and being able to achieve real asepsis. In addition, the common cans packaging on the market: iron, glass bottles, all kinds of soft packaging, all are completely sealed packing, can make the food in the vacuum state, prevent from the outside pollution, prevent the bacteria and so on, in the normal temperature conditions will not deteriorate.

In fact, canned fruit with guaranteed quality is original. The processing of canned fruits is essentially different from food such as drinks and pastries. Canned fruits appear to preserve fresh food, not just for delicious food. Therefore, the core of the canned fruit is the solid, that is, the food raw material. If the solids are added to the essence and pigment, it will become "false", but it will affect the selling.

Many people think that canned food, like other convenience foods, can only satisfy hunger but not nutrition. Some commentators also pointed out that canned foods suffer heavy losses after high temperature and high pressure. These rumors are directly related to your health, so you dare not fall in love with canned food. In general, the processing temperature of vegetables and fruits can not exceed 100 degrees C, so the loss of vitamin and other nutrients in the processing will not exceed their loss in frying, frying, frying and cooking.
