example 1

[0069] Example 1: After fully mixing 10 parts of 1-methylcyclopropene with 800 parts of α-cyclodextrin, 2 parts of quicklime and 50 parts of sec-butylamine phosphate, pour it into a packaging machine and pack it into a small package of 0.5g. The package is Use a pin to pierce two transparent holes before using the double-sided coated paper film.

example 2

[0070] Example 2: Mix 10 parts of 1-methylcyclopropene and 800 parts of α-cyclodextrin in a mixing mixer, add 50 parts of sodium metabisulfite, 100 parts of rosin and 2 parts of sodium carbonate, mix them and pour them into a glass-lined reactor. Close the lid of the kettle, then put steam into the jacket of the reaction kettle for heating, and start the glass-lined stirring at the same time, control the temperature in the kettle at 89°C and stir for 45 minutes, then cool down and discharge the material, and then pour the material into the granulator. Granulation; then mix the granulated material and excipients evenly, put them into a tablet machine for tableting, and pack the pressed tablets with plastic film or packaging, 2 to 4 tablets per small bag, and tie two transparent tablets when using. Eye.

example 3

[0071] Example 3: Fully mix 3 parts of 1-methylcyclopropene and 37 parts of α-cyclodextrin in a mixer, then add 10 parts of quicklime and mix to obtain A agent 25 parts of potassium metabisulfite and 20 parts of α-cyclodextrin Fully mix in a mixer, add 5 parts of soda lime and mix to obtain agent B. Agent A and agent B can be packed into two air-permeable bags respectively.

[0072] Example 4 Pour 2 parts of 1-methylcyclopropene, -35 parts of α-cyclodextrin, and 10 parts of bone glue into a glass-lined reaction kettle, close the lid of the kettle, and then inject steam into the jacket of the reaction kettle for heating. Turn on the glass lining and stir, control the temperature in the kettle at 84°C and stir for 32 minutes at a constant temperature, then cool down and discharge the material, then pour the material into a granulator, granulate, and mix the granulated material with 2 parts of sodium bicarbonate and 1 part of The magnesium stearate is evenly mixed, put into a ta...

Abstract

The cyclopropene consists of: 1-methyl cyclopropene 0.3-4 weight portions, preservative 5-40 weight portions, stabilizer 60-90 weight portions, slow releasing agent 0-20 weight portions and excipient 0-5 weight portions. The preservative is one or several of 2-aminobutane, phosphate of 2-aminobutane, hydrochloride of 2-aminobutane, sulfate of 2-aminobutane, lactate of 2-aminobutane, sodium pyrosulfite, potassium pyrosulfite, sodium bisulfite, potassium bisulfite and propyl isothiocyanate; the release controlling agent is one or several of lime, sodium bicarbonate, soda lime, reductive microcrystal alditol acid lignin polyacrylamide; and the stabilizer is one or several of cyclodextrin, rosin, silica gel and lac. The slow releaseing preservative has obvious functions of resisting rot and keeping freshness.

Description

technical field [0001] The invention belongs to an agricultural product antistaling agent, in particular to a cyclopropylene antistaling agent with dual functions of anticorrosion and freshness preservation. Background technique [0002] Cyclopropene can effectively inhibit the effect of ethylene on postharvest senescence of agricultural products. It has been proved that 1-methylcyclopropene can obviously inhibit the withering of flowers, keep the freshness of flowers, and prolong the life of fresh cut flowers. 1-methylcyclopropene can inhibit the aging of fruits such as apples, pears, and persimmons. Therefore, 1-methylcyclopropene is a very promising preservative. However, because the current production or experimental method is to use cyclopropene alone, the postharvest agricultural products need to be sealed during fumigation, and then transported and stored after fumigation. rot problem. Contents of the invention [0003] The technical problem to be solved by the ...
