Description

Ethylene absorption card

Technical Field

The utility model relates to the field of ethylene absorbents, in particular to an ethylene absorption card.

Background

Ethylene is a plant maturing hormone, volatile gaseous substances which can be automatically emitted from all plant tissues can be brought in by external combustion substances, and the physiological change of the plant can be influenced at a very small concentration (0.1 PPM), namely the degradation of the quality of vegetables and fruits can be promoted, and the stimulation of ethylene is required for the growth and flowering of the plant, so that the ethylene is an active ingredient which can stimulate the maturing effect. Ethylene is also produced by the growth of vegetables and fruits in the field, but in open spaces, ethylene easily drifts with the wind. However, the harvested vegetables and fruits are very different, because the ripe vegetables and fruits are stored in a closed space such as a carton, and a wound generates a large amount of ethylene during harvesting, the accumulated ethylene is not volatile, and the plants are stimulated to generate a larger amount of ethylene, so that the ripening and ageing of the plants are accelerated, and the storage quality and the service life of the vegetables and fruits and flowers are greatly reduced. Therefore, in order to absorb excessive ethylene and minimize the damage of the product to the ethylene, the aim of fresh keeping is fulfilled. The typical practice in the market is to put the bagged ethylene absorbent in a packaging carton, and the bagged ethylene absorbent is made by packaging ethylene absorbent particles by an outer bag, but the ethylene absorbent is large in volume and limited in placement space, and the outer bag has the risk of breaking bags and leaking materials to pollute vegetables and fruits.
