Description
Technical field
The invention belongs to agricultural products storage and preservation technical field, in particular to a kind of preservation method of fruit.
Background technique
The stem of gardening plant, leaf, flower, root and vegetables and fruit all have very big export capacity, and due to itself
It is also extremely important to the diet of the mankind containing nutrients such as minerals, vitamin, celluloses.Storage technique is that fruits and vegetables are raw
The continuation of production is the important guarantee of sustainable fruits and vegetables industry development, and global fruit all can lead to fruit due to overdone every year
Real a large amount of loss.In addition, ethylene can induce fruit decay, and fruit industry is caused to all suffer from huge economy every year
Loss.Therefore, finding effective preservation method is the major issue of Development of Fruit Industry, so needing to develop a kind of fresh keeping time
Long, of good preservation effect, inexpensive fruit preservation method.
Have more research to fruit freshness preserving at present, such as application number 201910004974.X, discloses a kind of fruit guarantor
Fresh composition, fruit antistaling agent and its preparation method and application, a kind of fruit freshness preserving composition, the fruit freshness preserving composition packet
Include the component of following parts by weight: 2~4 parts of modified potato starch, 0.1~0.3 part of sodium alginate, 0.5~2.0 part of glycerol,
0.05~0.3 part of epiphysin, 0.01~0.05 part of lysozyme.Modified potato starch, sodium alginate and glycerol are capable of forming good
Good coating liquid, epiphysin and lysozyme have anti-aging and bacteriostasis, can prevent infecting for fruit surface microorganism
And growth.It is fresh-keeping to fruit progress using fruit freshness preserving composition provided by the invention, it can preferably keep fruit color, fragrance
And taste, the room temperature storage phase is up to 30；As application number 201610730511.8 discloses a kind of fruit freshness preserving treatment fluid, including work
Property ingredient, sodium ascorbate, prochloraz and gibberellin, mass ratio is 1~4:1~4:0.5~2, fruit freshness preserving of the present invention
Treatment fluid is simple, can be made into only with a small number of raw materials, cost reduces, easy to process；As application number 201711240341.6 is public
A kind of fruit antistaling agent has been opened, has been prepared from the following raw materials: sucrose fatty ester, converted starch, nano-titanium dioxide, anti-sepsis
Acid, sodium chloride, hydroquinone, fumaric acid trehalose methyl esters, chitosan, sorbierite, hydrophobing agent, flos caryophylli extract, the leaf of bamboo mention
Take object and salicylic acid；After each raw material is mutually mixed generation chelatropic reaction, forming one layer on the surface of fruit has permeability
With the protective film layer of water preventing ability, while there is good bactericidal effect.It reduces fruit to rot, extends the freshness date of fruit.
Although present preservation method obtains certain effect, existing fruit preservation method is all fruit picking
Carry out spraying for fresh-keeping liquid etc. afterwards, pretreated preservation method carried out before picking and is had not been reported, in addition, salicylic acid, gibberellin,
Epiphysin is used in conjunction with to be had not been reported in field of fruit freshness keeping.
Summary of the invention
The present invention is in order to solve the above technical problems, provide a kind of preservation method of fruit.
It is realized particular by following technical scheme:
A kind of preservation method of fruit sprays fruit with compositional liquor in the previous day of fruit picking, will after picking
Fruit is transferred to confined space, is fumigated with liquid nitrogen, is then transferred in modified-atmosphere package and carries out cryopreservation.
Further, the compositional liquor, by epiphysin, gibberellin, salicylic acid by 0.1-0.5:0.02-0.08:0.2-0.7's
Mass ratio mixes.
Further, the epiphysin, concentration are 100~300 μm of ol/L, and the gibberellin, concentration is 10~100 μ
G/L, the salicylic acid, concentration are 200~500 μ g/L.
Further, the compositional liquor, the amount of spraying are 10-30ml/ fruit.
Further, the confined space, relative humidity >=85%.
Further, the liquid nitrogen, the volume ratio with confined space are 1:3000~1:1000.
Further, described stifling, time 10-30min.
Further, the modified-atmosphere package material is polyethylene material, with a thickness of 20~40 μm, air penetrability is 5300~
6800cm3/(m2·24h·0.1Mpa)。
Further, the cryopreservation temperature is 1~12 DEG C.
Technical principle of the invention:
Epiphysin (melatonin, MT), chemical name n-acetyl-5-methoxytryptamine, be all plants all have one
The endogenous indoles amine of kind.In the Different Organs such as plant roots, stem, leaf, flower, fruit, the presence of epiphysin has been had been acknowledged.It is existing to grind
Study carefully a variety of growth courses for showing that epiphysin takes part in plant, including germination, growth of seedling and aging etc..Epiphysin is in addition to making
Outside for dark signal and plant growth regulator, another obvious action is and protects the plants from the internal and environmental oxidation side of body
Compel related antioxidant activity.Gibberellin (GA3) is one of big endogenous hormones of plant five, is adjusted and controls plant growth and development
Each stage, GA3 can delayed fruit it is mature, to there is good fresh-keeping effect.Salicylic acid is a kind of regulating plant growth
With the phenolic compound of development, maturation and aging, it is able to suppress fruit and rots, delay post-harvest fruits ripening and senscence, keep fruit
Real quality, ethene suppressing synthesis improve the resistance to abiology adverse circumstance and induce post-harvest fruits to the resistance of pathogen and resist
Property correlated response.
Liquid nitrogen precooler technology is by the way that a large amount of field heats for adopting rear fruit institute band quickly scatter and disappear, to reach fast precooling
Carry out the aging after delayed fruit is adopted.Liquid nitrogen precooler technology does not have any harm using liquid nitrogen as cold source, to environment, with traditional machinery
Refrigeration is compared to can achieve lower temperature, and higher rate of temperature fall, the precooling speed of Liquid nitrogen precooler technology is fast, the time is short, peace
Quan Xinggao and pollution-free.
Modified-atmosphere package (MAP) is to generate certain controlled atmosphere environmental condition using the packaging bag of different gas permeability, because of it
Gas with various component proportion adjusts the metabolism of product, to extend the storage period of fruits and vegetables.MAP has storage effect good, convenient
Fast, a variety of advantages such as at low cost, at present on a variety of fruits and vegetables use and fresh-keeping effect highly significant, can reduce fruits and vegetables
Rotting rate and extension storage period.
The present invention have it is following the utility model has the advantages that
The present invention is fumigated with a kind of containing epiphysin, gibberellin and salicylic compositional liquor combination liquid nitrogen, can both be sterilized, and is pressed down
Ethylene synthase processed, and it can be passivated the activity of fruit enzyme, while, to keep the storage quality of fruit, can reach with fast precooling
Extend the fruit storage phase and promotes the purpose of fresh-keeping effect；It is easy to operate simultaneously, it improves efficiency, it is practical, it is answered convenient for promoting
With.
It is emphasized that being all that will carry out again spraying for the protection liquid such as fresh-keeping liquid, In after picking fruit in the prior art
In the case that fruit isolation is maternal, by environment and itself in the case where the induction of parent, amount of cure be it is very high, i.e.,
Just carry out spraying fresh-keeping liquid etc., fresh-keeping effect be still it is undesirable, therefore, the invention is answered before picking
Spraying with liquid greatly reduces the amount of cure of fruit, in the case where fruit is connect with female parent, compounds to fruit
Liquid sprays, and greatly reduces the curing induction that fruit is detached from after female parent, greatly extends the storage life of fruit.
