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 -5 g, and the rest are carrier substances; the above-mentioned carrier substance is the product of fully reacting 500g of animal fat with 100mL of sodium hydroxide and potassium hydroxide mixed aqueous solution, and the concentration of sodium hydroxide in the mixed aqueous solution is 17.25 mol L -1 , the concentration of potassium hydroxide is 1 mol 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. Among them, 1-methylcyclopropene is coated with α-cyclodextrin, and the active ingredient is 4%. Add after ...
