Description

A kind of preservation method for inhibiting apple brown stain and extending storage time
Technical field
The present invention relates to fruit storage technical field of preservation of fresh more particularly to a kind of inhibition apple brown stain and extend storage time Preservation method.
Background technique
Covering rich apple is that the Dongguang apple that tree body winter resistance is strong, fruity is sour is selected to make maternal, to select fruit quality excellent richness Scholar's apple makees male parent, the high-quality Big Apple of the cold-resistant of cross breeding.The kind fruit is larger, and average fruit weighs about 260 grams, in Ningcheng Regional early and middle ten days in October are mature, and background color is yellowish green, when full maturity can comprehensive red coloration, pulp is yellowish, crisp succulence, fragrant and sweet taste It is dense.It measures according to the study, Vitamin C content is up to 9.0~11.5mg/100g, and titratable acid content is 0.45%~0.60%, can Dissolubility solid content is also relatively high, is 14.5%~16.0%, and excellent taste, quality is superior, deep by the majority of consumers blueness It looks at.
But easily there is brown stain, pericarp dehydration shrinkage in storage period tissue (pulp and core) in its fruit, makes under quality Drop shortens storage and shelf life, and sale is become the bottleneck for covering rich apple industry by extreme influence.Upper base is produced at present This is using the storage place extending fruit storage period such as freezer and ventilation library, cellar, but if storage or way to manage are improper, storage 3~4 months fruits in hiding occur as soon as tissue (pulp and core) brown stain, lose commodity and edible value, make to orchard worker and storage family At certain loss.
Therefore, " covering rich " Apples quality is maintained using certain technology and methods, prevents its brown stain, extends its storage Service life covers rich Apple Culture to development and is of great significance.
Summary of the invention
In view of this, the embodiment of the invention provides the preservation method of a kind of inhibition apple brown stain and extension storage time, Main purpose is to solve the problems, such as that (the pulp and core) brown stain of Apple tissue and shelf-life are short.
In order to achieve the above objectives, invention broadly provides following technical solutions:
On the one hand, the embodiment of the invention provides the preservation method of a kind of inhibition apple brown stain and extension storage time, institutes The method of stating includes:
(1) it pre-harvest treatment: harvests first 5~7 days in apple and is handled with 1- methyl cyclopropene aqueous solution sprinkling;
(2) pick: picking in 145~155 days is big through the eight to ninety percent ripe of step (1) sprinkling processing, fruit after full-bloom stage It is small it is uniform, fruit colour is almost the same, injures the Apple of no disease and pests harm without colliding with, the fruit after adopting will be taken in field Shade protection is built, to avoid and burn day;
(3) it transports: the satisfactory apple of picking is transported as early as possible to storage place;
(4) calcium treatment: the Apple carpopodium of step (3) is cut short, and is immersed in calcium chloride solution and is impregnated, taking-up is dried in the air It is dry;
(5) it packs: by the processed Apple housing foam screen sheath of step (4), being packed into carton or plastics fruit case, in case The dedicated polyethylene film freshness protection package of apple is served as a contrast, freshness protection package opening is placed, and freshness protection package is equipped with venthole;
(6) it is pre-chilled: the Apple that step (5) are handled is put in storage pre-cooling immediately;
(7) soda lime is handled: after pre-cooling, the soda lime bound up with gauze being put into freshness protection package, tightens bag immediately Mouthful;
(8) it stores: after the completion of pre-cooling, fruit being subjected to slow cooling to -2~-1 DEG C of normal management;Storage period, it is fresh-keeping The control of bag internal oxygen gas concentration is in 19%~21% (preferably 20%), gas concentration lwevel control 0.3% hereinafter, ethylene concentration control System is in 5 μ L/L hereinafter, relative humidity is 85%~90%.
Preferably, the concentration of the 1- methyl cyclopropene aqueous solution is 200 μ L/L-400 μ L/L.
Preferably, described eight to ninety percent ripe refer to hardness of fruit 6.0kg/cm2More than, soluble solid content 14.0% or more.
Preferably, the concentration of the calcium chloride solution is 5%-7%, soaking time is 8-10 minutes.
Preferably, the aperture of the venthole on the freshness protection package is 20~40 μm, the density of the venthole is 1~2 Hole/cm2, the freshness protection package with a thickness of 0.015mm~0.02mm.
Preferably, the precooling temperature of the step (6) is 6 DEG C~8 DEG C, pre-coo time is 2~3 days.
Preferably, the weight for the soda lime that the step (7) is wrapped is 50~80 grams, generated for absorbing respiration of fruits Carbon dioxide, prevent fruit carbon dioxide injure.
Preferably, the concrete operations of the slow cooling: dropping 1 DEG C within every 3 days, be down to 0 DEG C within 18~24 days, stored at 0 DEG C 10~12 days, it is down to -2~-1 DEG C of normal management later and stores to terminating.
