Abstract
A storage method for peach features that in the storage period of peach, the ethylene with 5-50 micron 1/1 of concentration is applied for improving taste of peach and elongating storage period.
Description
Technical field
The present invention relates to a kind of method that improves the peach storage fresh-keeping effect, belong to agricultural product and adopt the field, back.The inventive method is applicable to alleviate when peach deepfreeze or air conditioned storage and damages to plants caused by sudden drop in temperature, and promotes the formation of peach flavor substance.
Background technology
Peach fruit juice multi-flavor U.S., fragrance is tempting, beautiful in colour, nutritious.Peach belongs to climacteric type fruit, and most kinds are gathered on the occasion of high temperature season, is easy to softening rotting after adopting.Cryopreservation can reduce the generation that the peach fruit is adopted back respiratory intensity and endogenous ethylene, effectively suppresses softening and corrupt, thereby prolongs storage period.But because the peach fruit has stronger sensitiveness to low temperature, be easy to damage to plants caused by sudden drop in temperature in cryopreservation, cause the bad change of fruit quality, edibility descends significantly even completely loses.The bad change of peach taste of fruit after damaging to plants caused by sudden drop in temperature mainly shows as the thin out or forfeiture of peach fragrance local flavor, even produces offending peculiar smell.Therefore how guaranteeing that the peach fruit can prolong storage period by cryopreservation, can guarantee that again flavor substance can normally form, is the key issue of peach preservation and freshness.
Ethene is the old and feeble hormone of a kind of maturation, and it can start the maturation of fruit, in order to prolong storage period, generally will control the synthetic and effect of ethene in storage.But the peach fruit is very sensitive to low temperature, very easily damages to plants caused by sudden drop in temperature when cryopreservation, and self synthesis capability of ethene is almost lost, and flavor substance can not form.Artificially increase ethene at duration of storage, help to alleviate and damage to plants caused by sudden drop in temperature, promote the synthetic of endogenous ethylene and flavor substance, improve the storage quality of peach fruit.
Summary of the invention
The synthesis capability of peach ethene during cryopreservation (refrigeration or air conditioned storage) descends, and peach is damaged to plants caused by sudden drop in temperature and normally after-ripening.The present invention is by manually applying the measure of exogenous ethylene, solves the after-ripening that causes because of the endogenous ethylene defective and the problem of local flavor synthesis capability forfeiture.
The invention provides the storage practice of a kind of peach, it is characterized in that, at the peach duration of storage, the people is for using exogenous ethylene.
Wherein at the peach duration of storage, the ethylene concentration of storage environment is controlled at 5～50ul/l.Described exogenous ethylene is selected from one or both in the following material: ethylene gas, ethephon (CEPHA).Described storage is a cryopreservation.The temperature of described cryopreservation is 0～2 ℃.
Amount ratio between each exogenous ethylene does not have specific (special) requirements.
Peach is at duration of storage, uses exogenous ethylene to handle, and promotes the synthetic of endogenous ethylene, can realize following beneficial effect: (1) alleviates and damages to plants caused by sudden drop in temperature; (2) start the after-ripening process of peach fruit during refrigerating; (3) formation of promotion flavor substance; (4) storage effect of raising peach.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.
Embodiment 1:
Select to pluck medium well peach fruit, transfer storage, 0～2 ℃ of reserve temperature through the laggard promoting the circulation of qi of precooling.The artificial ethylene gas that increases in air-conditioned cold store, the concentration range of ethene keep this concentration to storage to finish at 5～50ul/l.Because air-conditioned cold store is not an absolutely gas-tight, the ethylene concentration in the storehouse can reduce gradually, when ethylene concentration is lower than 5ul/l, needs to replenish.
Peach fruit main volatile aromatic substance changes
GC spectrogram when Fig. 1, Fig. 2 and Fig. 3 are peach fruit storage 10d, 30d and 50d is respectively discovered high concentration exogenous ethylene awakening technology processing peach fruit, all keeps good local flavor in each storage stage.Research also shows, high concentration exogenous ethylene awakening technology has been handled peach fruit balance sugar and organic acid is at the different metabolic rates of preserving the stage, make fruit flavor substance in storage reach balanced metabolism and release, improved the whole fragrant quality of later stage fruit.
Embodiment 2:
Select to pluck medium well peach fruit, transfer storage, 0～2 ℃ of reserve temperature through the laggard promoting the circulation of qi of precooling.Spray ethephon solution at fruit surface, make its concentration range that is converted into ethene, keep this concentration to storage to finish at 5～50ul/l.Preserve after 60 days, the comparison of the browning rate of fruit shows that according to low by 85.8% degree of staining increases by 78.6%.
Embodiment 3:
Select to pluck medium well peach fruit, refrigerate 0～2 ℃ of reserve temperature through after the precooling.Spray ethephon solution at fruit surface, make its concentration range that is converted into ethene, keep this concentration to storage to finish at 5～50ul/l.Preserve after 60 days, the comparison of the browning rate of fruit shows that according to low by 80.5% degree of staining increases by 75.3%.
Claims (5)
1, the storage practice of a kind of peach is characterized in that, at the peach duration of storage, the people is for using exogenous ethylene.
2, the method for claim 1 is characterized in that, at the peach duration of storage, the ethylene concentration of storage environment is controlled at 5～50ul/l.
3, the method for claim 1 is characterized in that, described exogenous ethylene is selected from one or more in the following material: ethylene gas, ethephon (CEPHA).
4, the method for claim 1 is characterized in that, described storage is a cryopreservation.
5, method as claimed in claim 4 is characterized in that, the temperature of described cryopreservation is 0～2 ℃.
