Description

Cell signal guide fruit colorant

Technical Field

The invention belongs to the technical field of fruit coloring agents, and relates to a cell signal guide fruit coloring agent.

Background

People eat fruits in daily life, and some fruits are transported from a far place and cannot be kept fresh, so the fruit shape, color, sugar and other factors of the fruits become factors considered by consumers. The fruit with good color and luster is often more attractive to purchase. In order to obtain good colour and luster of the fruit, it is necessary to provide it with a certain amount of growth regulators during the maturation phase, promoting the accumulation of pigments in the peel.

The fruit coloring agents currently used in the market are mainly ethephon and S-abscisic acid. The color enhancement effect of the S-abscisic acid is good, but the fruit soaking mode is needed when the S-abscisic acid is used, so that the labor is consumed; ethephon can be directly sprayed, so that the labor is saved, but the hyperchromic effect is poor, and the use amount is not well controlled. If the amount of the ripener is excessive and the use exceeds the standard, the content of the ripener for vegetables and fruits is excessive, and the damage to the health of human bodies is possibly caused. Through a large number of experimental researches, the following results are found: when the ethephon preparation is singly used in the coloring process of fruits, the phenomena of leaf falling, fruit grain threshing, fruit storage intolerance and the like of fruit trees are easily caused.

The prior art discloses a composition for promoting coloring and sweetening of grapes, which is disclosed in the patent No. CN201610864122.4, and comprises a component A (natural abscisic acid), a component B (monopotassium phosphate), a component C (one of lysophosphatidylethanolamine, lysophosphatidic acid or lysophosphatidylcholine), and a component D (one of sodium benzoate, levulinic acid and glutamic acid).

Disclosure of Invention

In order to solve the above problems, it is a technical object of the present invention to provide a cell signaling fruit colorant that can significantly improve the coloring time of fruits.

It is another object of the present invention to provide a safe and environmentally friendly cell signaling fruit colorant.

It is still another object of the present invention to provide a cell signaling fruit colorant which is effective in improving the color and quality of fruit.

It is a final object of the present invention to provide a cell signaling fruit colorant which is simple in composition, inexpensive to produce, and stable for long term storage.

In order to achieve the above object, the present invention has the following technical means.

The invention provides a cell signal guiding fruit colorant which comprises the following components in percentage by mass:

propyl dihydrojasmonate: 3 to 7 percent of the total weight of the mixture,

and (3) increasing the yield of amine: 2 to 4 percent of the total weight of the mixture,

emulsifier: 20 to 25 percent of the total weight of the mixture,

the balance of water.

Further, the propyl dihydrojasmonate is abbreviated as PDJ. The dihydrojasmonic acid propyl ester is an artificially synthesized jasmonic acid derivative with high biological activity, can be used as a cell guiding agent to induce fruit trees to generate ethephon, can increase fruit ears of the melastoma dodecandrum fruits, has a coloring function, does not cause fruit cracking and rotten fruits after picking, and does not affect fruit powder. The propyl dihydrojasmonate is convenient to use, can be sprayed on whole trees, does not influence spraying after fruit trees are bagged, and greatly saves labor cost.

Furthermore, the propyl dihydrojasmonate can obviously improve the anthocyanin content in the peel, reduce the chlorophyll a and b content and improve the color of the fruit; and the soluble solid content and the vitamin C content of the fruit can be obviously improved, the accumulation of total phenols and flavonoids in the fruit peel is promoted, and the fruit quality is improved.

Further, the chemical name of the yield-increasing amine is 2- (3, 4-dichlorophenoxy triethylamine), which is abbreviated as DCPTA. The yield increasing amine is a novel biological regulator, can effectively improve the photosynthetic efficiency of plants, and has various excellent performances on the growth and development of the plants. The yield-increasing amine has no toxicity, no pollution and no residue, and can also greatly improve the utilization rate of the fertilizer. And the fruit trees also have excellent effects of resisting diseases and pests, barren, drought, freezing and the like.

Furthermore, the yield-increasing amine is matched with the propyl dihydrojasmonate to effectively shorten the time of ethephon generation induced by the propyl dihydrojasmonate, so that the time of coloring fruits can be effectively shortened, and the quality of the fruits is guaranteed.

Further, the emulsifier is polyethylene glycol and polysorbate-80. The polyethylene glycol and polysorbate-80 are common emulsifiers, have good emulsifying property, and have the advantages of low cost and no toxicity to human bodies.

Compared with the prior art, the invention has the advantages and effects that: (1) the yield-increasing amine contained in the colorant is matched with the dihydrojasmonic acid propyl ester, so that the coloring time of fruits can be effectively shortened; (2) the colorant has the effect of uniform coloring; (3) the colorant contains the propyl dihydrojasmonate, so that the color and the quality of the fruits can be effectively improved, soft fruits and rotten fruits cannot be caused, and the fruit cracking rate is effectively reduced; (4) the colorant can effectively increase the sweetness and the mouthfeel of the fruits; (5) all components of the colorant do not generate harmful substances, so that the colorant is safer and more environment-friendly.
