Problems solved by technology

But the following problems exist in such fresh-keeping methods: if 1-methylcyclopropene or chlorine dioxide is used alone to process fruits and vegetables, due to the lack of synergy between the two, the fresh-keeping time is extremely short and the effect is not significant, which cannot meet the storage requirements. , transportation and sales needs; if 1-methylcyclopropene and chlorine dioxide are used for preservation at the same time, the two cannot be used at the same time because of the redox reaction between the two in the same fruit and vegetable box, resulting in failure
This secondary treatment operation process results in large labor consumption, large box damage, large secondary damage to fruits and vegetables, and high cost, and even cannot be implemented at all in some environments.
In addition, the existing commercially available 1-methylcyclopropene sustained-release capsules can release 1-methylcyclopropene gas after dissolving the shell with water. 1-Methylcyclopropene can only be released by adding water to the capsule release container. If this operation is carried out in the fruit and vegetable box, the workload is very large and cumbersome.
The existing commercially available chlorine dioxide slow-release agent is a product that is used while synthesizing. This type of product uses liquid sulfuric acid or hydrochloric acid as the acid donor, which has the risk of strong acid corrosion and the pungent smell of hydrochloric acid, which is harmful to human health. The amount of chlorine dioxide released per unit time is large, which can easily cause bleaching effect on fruits and vegetables, reducing the quality of fruits and vegetables, and the chlorine dioxide released by this product does not last long, and harmful bacteria on fruits and vegetables cannot be stored within the required fresh-keeping time. achieve inhibition

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and specifically refers to a 1-methylcyclopropene and chlorine dioxide graded releasing device and a preparation method thereof. Background technique [0002] Fresh fruits and vegetables are perishable after picking. One of the reasons is that many fruits and vegetables are respiratory climacteric agricultural products. The ethylene in the environment or the ethylene released by the fruits and vegetables will bind to the ethylene receptors in the fruits and vegetables, and accelerate the destalking, aging and softening of fruits and vegetables. , rot; the second reason is that the picking period of most fruits and vegetables is in the high temperature season, and the germs on the fruits and vegetables are easy to multiply at this time, causing mildew and corruption of the fruits and vegetables picked. Therefore, post-harvest fruits and vegetables need to be kept fre...
