Description

The painted method of rear autumn Ji plum fruit is adopted in a kind of promotion

Technical field

The invention belongs to fruit processing technology field, be specifically related to a kind of promotion and adopt the painted method of rear autumn Ji plum fruit.

Background technology

Autumn Ji Lee be originate in Japan eat Lee's new varieties raw, have late-maturing, fruit is large, beautiful in colour, taste is sweet, edible rate is high and the advantage such as storage tolerance, deeply like by consumer.In recent years, the introducing and planting all such as Shandong, Henan, Sichuan and Fujian.Painted poor at ground autumn Ji's plum fruits such as Fujian, really face can be painted preferably to only have the part of sunlight direct irradiation, and fruit color is uneven.This Fujian temperature in period may grown with autumn Ji plum fruit is higher relevant.There are some researches show that high temperature can affect fruit color.Meanwhile, orchard worker conveniently transport often fruit also non-full maturity be just gather, now autumn Ji plum fruit mostly is yellow green, and only part fruit has painted on a small quantity.Fruit appearance color and luster is one of important indicator of fruit quality proterties, the commodity of painted not good serious fruit.Research shows that consumer orientation is in thinking that red fruit quality is better.Therefore, research and development promote that the method for adopting rear autumn Ji plum fruit painted is significant.

Summary of the invention

The object of the present invention is to provide a kind of promotion to adopt the painted method of rear autumn Ji plum fruit, effectively improve fruit colour, improve its commodity.

For achieving the above object, the present invention adopts following technical scheme:

The concrete steps that the painted method of rear autumn Ji plum fruit is adopted in a kind of promotion are as follows:

(1) fruit is selected: carried out selecting process by the autumn Ji plum fruit of gathering, and removes sick fruit, cull fruit;

(2) fruit classification: according to the difference of autumn Ji plum fruit size and maturity, it is carried out in batches, improves the uniformity with a collection of fruit;

(3) fruit precooling with dry: autumn Ji plum fruit is placed on and shady and cool dry locates aeration-drying 24 hours;

(4) irradiate under forwarding the fruit after drying to artificial light source, illumination 6-8 days under 20 DEG C of conditions, fruit and pigmentable.

Remarkable advantage of the present invention is: colorize method provided by the invention can make autumn Ji plum fruit uniform coloring, and coloring effect is good, and without the need to passing through Chemical treatment, safety non-toxic, simple, easy to operate.

2, the autumn Ji plum fruit picked out is carried out classification according to size;

3, autumn Ji plum fruit is placed on shady and cool dry place's aeration-drying 24 hours;

4, get 30 dry after autumn Ji plum fruit forward under artificial light source and irradiate (intensity of illumination 10000lx), place after 8 days under 20 DEG C of conditions, 30 the autumn Ji Lee pericarp equal shiny red.

The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
