Embodiment 1

[0068] Embodiment 1: Preparation of cyclopropene inclusion complex powder

[0069] The 1-MCP gas after the synthesis and purification is passed into 10 kilograms of absorption liquids that are composed of 14.5% α-cyclodextrin, 5% white carbon black and 80.5% water, and carry out inclusion absorption at normal temperature, and the stirring speed is 300 revolutions per minute, continue to feed 1-MCP gas for 3 hours, then quickly filter the absorption liquid mixture, add absolute ethanol to wash after the suction filtration, and then suction filter, and finally dry at room temperature to obtain 1.9 kg containing 3.0 % 1-methylcyclopropene inclusion complex powder.

Embodiment 2

[0070] Embodiment 2: Preparation of cyclopropene inclusion complex powder

[0071] The synthesized and purified 1-MCP gas is passed into 10 kg of absorption liquid composed of 1% alkylated α-cyclodextrin, 49% white carbon black, and 50% water, and inclusion absorption is carried out at room temperature. The stirring speed is 300 rpm, and 1-MCP gas is continuously fed for 5 hours, and then the absorption liquid mixture is subjected to rapid suction filtration, and after the suction filtration is completed, absolute ethanol is added for washing, and then suction filtration is performed, and dried in the air at room temperature to obtain 4.95 kg Contains 0.07% 1-methylcyclopropene inclusion complex powder.

Embodiment 3

[0072] Embodiment 3: Preparation of cyclopropene inclusion complex powder

[0073] The 1-MCP gas after the synthesis and purification is passed into 10 kg of absorption liquid composed of 49% esterified α-cyclodextrin, 0.1% white carbon black and 50.9% water, and carries out inclusion absorption at normal temperature, stirring The speed is 300 rpm, and the 1-MCP gas is continuously introduced for 2 hours, and then the absorption liquid mixture is subjected to rapid suction filtration. 3.2% 1-methylcyclopropene inclusion complex powder.

Abstract

The invention provides a cyclopropene preservative, which is characterized by containing 0.1 to 99 mass percent of cyclopropene coating material powder, 0.1 to 98 mass percent of compound, composition or material releasing water molecules, and 0 to 98 mass percent of one or more assistants. The invention also provides the preparation method and packaging method of the cyclopropene preservative. The preservative is convenient for use and has a remarkable preservation effect.

Description

technical field [0001] The invention relates to a cyclopropene antistaling agent and a preparation method thereof. The antistaling agent is used for the preservation of fruits, vegetables and flowers. Background technique [0002] Ethylene is currently recognized as the mature and aging hormone of fruits, vegetables and flowers. Ethylene can accelerate the aging and corruption of fruits, vegetables and flowers, causing them to lose their own value. In order to reduce postharvest senescence of fruits, vegetables and flowers and prolong storage time, the production of endogenous ethylene should be reduced as much as possible and the effect of exogenous ethylene should be inhibited. 1-Methylcyclopropene (1-MCP for short) is the best ethylene inhibitor found so far, it can irreversibly bind to ethylene receptors, it can not only block the endogenous ethylene production of fruits, vegetables and flowers, but also inhibit the exogenous ethylene production. The effect of ethylene ...
