Preparation method of oxygen-enriched melon and fruit ripening agent

Abstract

The invention relates to a preparation method of an oxygen-enriched melon and fruit ripening agent, and belongs to the technical field of agricultural product additive preparation. The method comprises the steps of burning, melting and mixing ferric hydroxide and vermiculite at a high temperature to improve the oxygen carrying capacity of a calcined material; dissolving the inside of the calcined material by using a hydrochloric acid, gathering iron ions on the surface, and forming ferriporphyrin to be adsorbed to the inside of the calcined material employing the calcined material as a catalyst in an acetonitrile environment to improve the combining capacity of the ferriporphyrin and oxygen; and finally mixing the ferriporphyrin with a nutrient and then supplementing oxygen to prepare the oxygen-enriched melon and fruit ripening agent. The problems that the taste of melons and fruits is changed and the physical health is affected after long-term eating due to the fact that a traditional ripening agent contains harmful substances and the harmful substances are remained on the surfaces of the melons and fruits, and the fruit peel is free of luster and incomplete in green removal due to oxygen deficiency and carbon dioxide accumulation during ripening are effectively solved. The prepared oxygen-enriched melon and fruit ripening agent contains a lot of oxygen, so that the ripening effect is good and the taste of the melons and fruits and the physical health of a person are not affected.

Description

technical field [0001] The invention relates to a preparation method of an oxygen-enriched melon and fruit ripening agent, and belongs to the technical field of preparation of agricultural product additives. Background technique [0002] Climacteric fruits, such as watermelon, banana, mango, papaya, avocado, etc., are usually harvested when the fruit reaches physiological maturity, that is, when the volume and weight no longer increase, but the fruit is still inedible at this time, and the peel is green. The pulp is hard, sour, and astringent, and it needs to go through a stage called "post-ripening" to reach an edible state with good color, flavor and taste. For melon farmers, melons ripening one day earlier means that they can be sold at a better price, which has led to the widespread use of ripening agents by melon farmers. [0003] At present, the traditional ripening agents mainly include paclobutrazol, 2,4-D, ethephon and other ripening agents, among which paclobutraz...

Problems solved by technology

[0004] The technical problem to be solved by the present invention: traditional ripening agents contain harmful substances, which will remain on the surface of melons and fruits, which will change the taste of melons and fruits, and long-term consumption will affect the health of the body. As a result of the problem of dull peel and incomplete degreening, the present invention uses ferric hydroxide and vermiculite to calcine, melt and mix at high temperature to increase the oxygen-carrying capacity of the calcined product, and then uses hydrochloric acid to dissolve its interior to make its surface rich. Collect iron ions, and then use the calcined product as a catalyst. Under the acetonitrile environment, iron porphyrin is formed and adsorbed inside the calcined product, which improves its ability to combine with oxygen. Finally, it is mixed with nutrients and supplemented with oxygen to obtain oxygen-enriched Type melon and fruit ripening agent, the present invention uses degradable vermiculite that can fertilize the soil as the base material, increases the oxygen carrying capacity through modification, and mixes it with nutrients, and uses it in the ripening period of melons and fruits to provide oxygen and nutrients, while increasing the oxygen content of the roots of melons and fruits, promoting root growth, increasing the absorption of nutrients, and further promoting fruit ripening and growth, effectively solving the traditional use of ripening agents containing harmful substances that will remain on the surface of melons and fruits. Changing the taste of melons and fruits, long-term consumption will affect the health of the body, and when ripening, the lack of oxygen and the accumulation of carbon dioxide will cause the problems of dull skin and incomplete degreening. The oxygen-enriched melon and fruit ripening agent prepared by the present invention Enriched with a large amount of oxygen, the ripening effect is good, and it will not affect the taste of melons and fruits and human health
