The present invention relates to a device for controlling the aging of a portable fruit, and a device for controlling the freshness and aging of fruits by controlling the absorption and release of ethylene, which is a plant hormone, which affects the aging of fruits.

Ethylene, which is the aging agent used in fruit ripening (ethene), has C2H4, C = C bond length of 1.339A double bond. A molecular weight of 28.1, a melting point of 169.2, a boiling point of -103.7, and a specific gravity of 0.6246 (146). Ethylene is the most basic material in the petrochemical industry and is a very important substance in the synthetic organic chemical industry, and its production or usage is a measure of the scale of the chemical industry in the country. As a combustible gas with a colorless directionality, the mixture with air tends to cause an explosion when it is burned, and it burns in the air with a sooty red flame.

It is also a ripening hormone of water, which promotes the maturation of fruit. It also inhibits the growth of stem, root, growth of shoots, growth of shoots and buds, and the growth of stem, roots, It promotes the formation of myelin, the seed germination of some species, the growth of the upper goblet, the formation of the goblet, the aging and desorption of the organ.

Techniques that combine traditional fruits with ethylene have adjusted their absorption and release separately, especially focusing on mass transport and storage, and the volume and capacity of the device or material is so large that it has been very difficult for consumers to use it directly.
