Embodiment 1

[0040] This embodiment provides a composite fruit and vegetable fresh-keeping mat containing a two-component gas release layer and a 1-MCP release layer, which is prepared through the following steps:

[0041] Take a cast polypropylene film with a thickness of 0.01mm (the air permeability is 2000cm 3 / m 2 d pa), the 1-MCP powder is dispersed on the casting polypropylene film layer, and the consumption of the 1-MCP powder on the casting polypropylene film per square meter is 50mg with 1-MCP effective amount wherein, carry out heating Press bonding, obtain the fixed 1-MCP release layer (the thickness of 1-MCP release layer is about 40 microns) on the cast polypropylene film layer;

[0042] Get the directionally stretched polypropylene film that thickness is 0.05mm (air permeability is about 300cm 3 / m 2 d pa), sodium pyrosulfite, sodium chlorate and citric acid are evenly dispersed on the oriented stretched polypropylene film, and the consumption of per square meter of orient...

Embodiment 2

[0048] This embodiment provides a composite fruit and vegetable fresh-keeping mat containing a two-component gas release layer and a 1-MCP release layer, which is prepared through the following steps:

[0049] Take a cast polypropylene film with a thickness of 0.03mm (the air permeability is about 1600cm 3 / m 2 d pa), the 1-MCP powder is dispersed on the casting polypropylene film layer, and the consumption of the 1-MCP powder on the casting polypropylene film per square meter is 55.6mg in terms of the effective amount of 1-MCP wherein, carry out Thermocompression bonding, obtains the fixed 1-MCP release layer (the thickness of 1-MCP release layer is about 45 microns) on the cast polypropylene film layer;

[0050] Take a biaxially oriented polypropylene film (the air permeability is about 400cm) with a thickness of 0.03mm 3 / m 2 · d · pa), sodium pyrosulfite, potassium chlorate and tartaric acid are evenly dispersed on the biaxially stretched polypropylene film, and the con...

Embodiment 3

[0055] This embodiment provides a composite fruit and vegetable fresh-keeping mat containing a two-component gas release layer and a 1-MCP release layer, which is prepared through the following steps:

[0056] Take a cast polypropylene film with a thickness of 0.03mm (the air permeability is about 1600cm 3 / m 2 d pa), the 1-MCP powder is dispersed on the cast polypropylene film layer, and the consumption of the 1-MCP powder on the cast polypropylene film per square meter is 60mg in terms of 1-MCP effective amount wherein, carry out heating Pressure bonding, obtain the fixed 1-MCP release layer (the thickness of 1-MCP release layer is about 50 microns) on the cast polypropylene film layer;

[0057] Another cast polypropylene film (with an air permeability of about 500cm) with a thickness of 0.02mm 3 / m 2 d pa), Potassium sulfite, sodium chlorate and tartaric acid are evenly dispersed on the casting polypropylene film, and the consumption of potassium sulfite on the casting p...

Abstract

The invention provides a combined fruit and vegetable fresh-keeping pad and a preparation method and application thereof. The combined fruit and vegetable fresh-keeping pad comprises a non-woven cloth layer, a 1-methylcyclopropene release layer, a first thin film layer, a bi-component gas release layer and a second thin film layer in sequence. The 1-methylcyclopropene release layer is formed by fixing 1-methylcyclopropene powder on the first thin film layer. The bi-component gas release layer is formed by fixing a sulfite, chlorate and slow-release agent mixture to the second thin film layer. The air permeation volume of the first thin film layer is 1500-2000 cm<3>/m<2>.d.pa, and the air permeation volume of the second thin film layer is 200-500 cm<3>/m<2>.d.pa. The combined fruit and vegetable fresh-keeping pad can prevent quality deterioration caused by senescence or rottenness of stems or fruits, prolong the shelf life of picked grapes and reduce the phytotoxicity of SO2 gas. The preparation method of the combined fruit and vegetable fresh-keeping pad is simple, easy to implement and low in cost.

Description

technical field [0001] The invention relates to a fruit and vegetable fresh-keeping mat and its preparation method and application, in particular to a composite fruit and vegetable fresh-keeping mat and its preparation method and application. Background technique [0002] In recent years, my country's fruit and vegetable industry (including the flower industry) has made great achievements. The output of fruits and vegetables is huge, but the losses caused by ripening, aging and rot in the process of storage and transportation are also staggering. At present, reasonable and effective storage and preservation of fruits and vegetables after harvesting Technology has received widespread attention from the industry. [0003] Sulfur dioxide (SO 2 ) is a recognized most effective fruit and vegetable preservative, but there is a bleaching problem, and SO 2 More and more people pay attention to the residual problem of disposal and the harm to human body and environment. [0004] Ch...
