Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the disadvantages of the current banana fresh-keeping method, such as short fresh-keeping storage time, poor fresh-keeping effect, and easy residual toxic chemical substances, which endanger human health, a kind of anti-corrosion Chinese herbal medicine such as mustard seed is ground into powder, and water Submerge, then add ethanol solution and rice to soak, dry naturally, grind powder, mix with fine rice bran, make the active ingredients in the Chinese herbal medicine adsorb on the surface of rice and fine rice bran, and then roast and smoke under the action of charcoal, The organic components in the rice and fine rice bran penetrate into the banana peel, forming a dense film between the inner membrane layer of the banana peel and the banana pulp to isolate the outside air, so as to achieve the purpose of keeping bananas fresh, effectively solving the problem of traditional methods of keeping fresh. The effect is not good, and the problem of toxic chemical substances is easy to remain. The present invention has a better fresh-keeping effect, is safe and environmentally friendly, has no toxic substance residue, and has no harm to human health
