In recent years, as a healthy and fashionable sport, outdoor sports is no longer a minority of patents, but more and more people's favor. Naturally, all kinds of outdoor equipment are highly concerned by outdoor sports enthusiasts, especially the "food for the people" is an important basis for outdoor sports. In the natural environment, the convenience and safety of diet is the most important. If nutrition is balanced at the same time, it will lay a good health foundation for outdoor sports. Canned food is the best choice to satisfy "convenience, safety and nutrition".

First of all, canned food can ensure maximum safety and hygiene. The technology principle of tank storage processing is that the food is loaded into the container after the extraction of air to form a vacuum. The seal makes the external bacteria unable to enter again. The bacteria will kill the remaining bacteria, and the bacteria do not grow and reproduce, and the food will not be corrupted. But canned food is not needed to be placed in the refrigerator and can be stored at room temperature. In the vacuum and aseptic state of the canister, the color, aroma and taste can be preserved to a maximum and a longer shelf life.  It has been reported abroad that after several decades of storage, the canned food is still in good condition and meets the edible standard.

In addition, canned food is not only safe and healthy, but also can provide rich nutrition for the body. Research shows that some nutrients in canned foods are higher than those made in our daily cooking.  Carotene and lycopene are all very stable to heat, so they will not lose.  And after heating and boiling, their absorptivity will increase greatly.  Canning process will also play a "concentrated" role, so, carotene, lycopene, not only will not lose, but also increase. Canned carrots contain 50% more carotene than fresh ones, and canned tomatoes contain twice as much lycopene as fresh ones. Minerals are not afraid of heating, so the content will not drop, and sometimes will increase. With canned fish, the sterilization process not only has no effect on the nutrients such as protein, iron, zinc, iodine and selenium in fish, but also makes the fish bone crisp and soft and dissolves a large amount of calcium. Therefore, the calcium content of canned fish is increased by more than ten times more than that of fresh fish.

The canned food with convenient and safe nutrition in the natural environment of lack of dietary resources can make people maintain high physical function and bring pleasure of body and mind, and enjoy all kinds of experience brought by outdoor sports.
