Embodiment Construction

[0018] The mass content of active ingredients in 10g of green and safe fruit and vegetable preservatives is: ethanol 5.05g, hexanal 0.32g, 1-methylcyclopropene (1-MCP) 4.7×10-5g, and the rest are carrier substances; the above-mentioned carrier substances are The product of fully reacting 500g of animal fat with 100mL of a mixed aqueous solution of sodium hydroxide and potassium hydroxide. The concentration of sodium hydroxide in the mixed aqueous solution is 17.25mol·L-1, and the concentration of potassium hydroxide is 1mol·L-1.

[0019] Concrete preparation process is as follows:

[0020] 1. Melt tallow fatty acid and add the corresponding proportion of sodium hydroxide and potassium hydroxide mixed aqueous solution to fully react;

[0021] 2. After the reaction is complete, add 720g of ethanol, 45.4g of hexanal, and 0.2g of 1-methylcyclopropene, and stir evenly, wherein 1-methylcyclopropene is coated with α-cyclodextrin, and the active ingredient is 4%. Add after dissolving...

Abstract

The invention relates to a green and safe fruit and vegetable fresh-keeping agent, a preparation method and a use method. The fruit and vegetable fresh-keeping agent is characterized by comprising the following active ingredients: 5.05g alcohol, 0.32g hexanal, 4.7*10<-5>g 1-methylcyclopropene, and the balance of a carrier substance. The agent has the positive effects that the agent is good in fresh keeping effect, convenient and simple to use, pollution-free, free from residues, and harmless to a human body.

Description

technical field [0001] The invention belongs to a fresh-keeping agent for fruits and vegetables, in particular to a green and safe antistaling agent for fruits and vegetables, a preparation method and a use method, and specifically achieves the purpose of keeping fruits and vegetables fresh by inhibiting the release of ethylene after the fruits and vegetables are harvested. Background technique [0002] For a long time, fruit and vegetable preservation technology has been the key to prolonging the period of fruit preservation and alleviating the contradiction between supply and demand. Fruit and vegetable storage and preservation is one of the most important technical links in the production, supply and marketing of fruits and vegetables. The general fresh-keeping methods of fruits and vegetables include vacuum nitrogen filling fresh-keeping method, modified atmosphere storage method in polyethylene bags or boxes, low-temperature storage method, chemical agent spraying, soak...
