Description

Ethylene generator for fruit ripening and fruit ripening method using the same

The present invention relates to an ethylene generator for promoting ripening of fruits and a method for promoting ripening of fruits using the same. More specifically, the present invention can be easily carried out by absorbing 2-chloroethyl phosphonic acid into an absorbent material, using an ethylene generator composed of a semi-solidified ethylene generator and a basic substance, and an ethylene generator. It is about how to promote fruit ripening.

Among the fruits harvested from the fruit farmers, ripened fruits such as young persimmons, which are not ripened, or immature fruits are generally not commercially available due to low sugar content, high hardness, acidity and poor pigmentation. After long-term storage, it is natural to get a good post-mortem, but for this, a long time is required as well as a separate storage space, and it is frequently sold after a timely sale. Induced, and had a problem that the fruit may be damaged during the storage by rats and insects. In addition, in order to shorten the harvesting period of immature fruits that have not been ripened in a timely manner due to inadequate fruit growing conditions, promotion of ripening of immature fruits is often required in fruit farmers.

In general, ripening of fruit is a physiological effect of increasing the savory taste of the fruit, such as increase in sugar content, decrease in hardness and softening of the fruit, reduction of acidity, enhancement of coloration, and increase of flavor components. In order to achieve the fruit ripening of the fruit, a method of promoting fruit ripening using an industrial carbide has been mainly used.

However, the conventional method of promoting the ripening of fruit by using the carbite can generate harmful toxic gas which is harmful to the human body, which may harm the health of the worker when the fruit is ripened. I had it.

On the other hand, ethylene promotes ripening of fruits by enhancing the coloring of fruits such as persimmons, plums, citrus fruits, sesame seeds and bananas, and fruits and vegetables such as tomatoes and peppers, and softening the flesh. Aged fruit, which has an inducing physiological action, is known to produce ethylene, and in recent years, attempts have been made to promote fruit ripening using it.

However, since ethylene is a gaseous substance that is difficult to handle and flammable, 2-chloroethyl phosphonic acid, which has recently been widely used in trade names such as 'Ethephon' or 'Ethrel' instead of ethylene. A method of promoting ripening of fruit using an aqueous solution of hereinafter (hereinafter referred to as etepon) is used.

The above-mentioned ethephon has a stable solution when the pH is 2 or less, but easily decomposes and generates ethylene when the pH is 5 or more. On the other hand, since the pH range of the plant tissue has a value of approximately 5 to 6, conventionally, by using this, in order to promote ripening of the fruit, etepon is directly added to the fruit, the fruit is immersed in the etepon, or the etepon By spraying the fruit onto the fruit, ethylene is generated as the ethone injected, immersed or sprayed into the fruit is decomposed to promote the ripening of the fruit.

However, the method for promoting the ripening of fruit by treating the above-mentioned conventional fruit ripening accelerator etepon directly on the fruit is cumbersome and takes a long time because the fruit must be treated with etepon, and the etepon on the inside and the surface of the fruit This residue was unsanitary, and it was difficult to control the throughput of etepon according to the immature state of the fruit.

In addition, the above-mentioned etepon is a liquid material, which is difficult to handle because the etepon is dispersed in the air when the etepon is treated by spraying on the fruit, etc. Since there is a problem that can not be used under, there was a limit to the practical use in the industry of etepon, a conventional after-promoting agent.

Therefore, there has been a continuous demand for the development of a ripening accelerator that can effectively solve the above problems and ripen fruiting, but there is almost no conventional technology related thereto.

After all, the main object of the present invention is easy handling and fruit ripening in a short time in the fruit ripening treatment, fruit ripening can adjust the degree of ripening of fruit without remaining residues on the inside and surface of the fruit It is to provide an ethylene generator for promotion.

In addition, another object of the present invention to provide a method that can facilitate the ripening of fruit using the ethylene generator described above.
