The invention discloses a chitosan and a preparation method thereof. The main component of chitosan is chitosan gel. The chitosan gel includes the following components in parts by weight: 25 parts by weight of chitosan, lactic acid solution 13 parts by weight, 12 parts by weight of glycerin, 12 parts by weight of modified xylitol, 7 parts by weight of L-carnitine tartrate, 13 parts by weight of modified acetic acid, 4 parts by weight of ethephon, 1 part by weight of ginsenoside extract, angelica extract 1 weight part of chitosan, the balance is deionized water, the preparation method of chitosan, by adding modified xylitol and modified acetic acid, greatly improves the air permeability, antibacterial property and ripening rate of chitosan , and the addition of ethephon further promotes the ripening of fruits and vegetables, and solves the problem that the existing chitosan cannot meet people's needs in terms of antibacterial properties, air permeability and ripening of fruits and vegetables. |
