Abstract

The present invention relates to the field of fruit preserving agents. The present invention discloses a fresh peach preserving agent which contains 0.5 to 1.5 parts by weight of potassium permanganate, 1 to 3 parts by weight of nanometer silver and 3 to 9 parts by weight of sepiolite powder. A preserving method of the fresh peach preserving agent comprises: pretreatment: spraying 0.4 to 0.6% of a solution of calcium chloride before the fresh peaches are picked; precooling treatment: precooling the fresh peaches after picked to storage temperature; selection and bagging: bagging the fresh peach after selected into preserving bags, simultaneously fastening the bags after the fresh peach preserving agent is put in the bags, and putting the bags in cold storages with 85 to 90% of humidity and at storage temperature for preservation. The present invention has the active effects of lowering respiratory intensity of the peaches, delaying breathing transition and after-ripening time, and prolonging the preservation time, and compared with the existing preserving agent, the preservation time can be prolonged for 10 to 20 days.

Description

Fresh-keeping agent for peach and preservation method thereof
Technical field
The present invention relates to a kind of fruit antistaling agent field, relate to a kind of fresh-keeping agent for peach and peach preservation method thereof especially.
Background technology
At present, more influentially on the market can be used for the CT-drupe class fruit special anti-corrosion fresh-keeping mat that the fresh-keeping fresh products of peach is national agricultural products fresh-keeping center, and matching used with it freshness protection package, disadvantage when this technology is used for the peach fresh-retaining preserving is: to storehouse temperature required precision height, when the storehouse temperature fluctuates greater than 0.5 ℃, easily cause bag interior humidity excessive, produce to drip and reveal, antistaling agent injury phenomenon occurs, the water droplet in the bag is prone to the peach rotten.Also have report, the HCF antistaling agent of development, it only has the effect of certain antiseptic and inhibiting bacteria function, reduction respiratory intensity to 12 days short-term storage test.Therefore, also need a kind of more practical, economic, effective fresh-keeping agent for peach and preservation method thereof at present.
Summary of the invention
(1) technical problem that will solve
The objective of the invention is at above-mentioned the deficiencies in the prior art, a kind of fresh-keeping agent for peach that prolongs storage period is provided;
Another object of the present invention provides a kind of bright peach preservation method.
This technical scheme is applied to actual preservation and freshness, can reduce peach respiratory intensity, postpone climacteric, delay ripening time, prolong storage period.
(2) technical scheme
To achieve these goals, the present invention adopts following technical scheme:
Fresh-keeping agent for peach of the present invention is characterized in that it contains potassium permanganate 0.5-1.5 weight portion, Nano Silver 1-3 weight portion and foaming stone powder 3-9 weight portion.
Preferably, described fresh-keeping agent for peach contains potassium permanganate 1 weight portion, Nano Silver 2 weight portions and foaming stone powder 6 weight portions.
Potassium permanganate can absorb the ethene of breathing out in the peach storage; Nano Silver mainly plays bactericidal action; The foaming stone powder can increase the antistaling agent volume, and it is effective to absorb ethene.Potassium permanganate, Nano Silver and foaming stone are product solds on the market, perhaps can prepare according to a large amount of existing documents and materials.
The preparation method of fresh-keeping agent for peach of the present invention is: fully be dissolved into water in according to itself and 1: 6 part by weight of water potassium permanganate, again to wherein adding Nano Silver and foaming stone powder and stirring, obtain a kind of mixture,, in whipping process, can add water in order to stir fast; And then mixture dried naturally or dry, so promptly obtain fresh-keeping agent for peach of the present invention.Fresh-keeping agent for peach is contained in usually in the ventilative cotton bag of dark colour and seals preservation.The fresh-keeping agent for peach use amount is the 1.2%-2.5% of bright peach weight.
The bright peach preservation method of the present invention is characterized in that this method comprises the steps:
(1) pre-treatment: bright peach is sprayed a weight concentration 0.4%-0.6% week about before harvesting calcium chloride water, spray 2-3 time continuously;
(2) measure the freezing point of plucking bright peach, determine reserve temperature, reserve temperature should be higher than 1.2-2.2 ℃ of bright peach freezing point;
(3) pre-cooled processing: the bright peach that will pluck placed temperature 7-9 ℃, the pre-cooled 11-13 of freezer hour of humidity 85%-90%, temperature of ice house was transferred to bright peach reserve temperature again;
(4) select, pack: when bright peach temperature reaches reserve temperature, bright peach is through in the freshness protection package of packing into after selecting, the foregoing fresh-keeping agent for peach of also packing into simultaneously, its amount is the 1.2%-2.5% of bright peach weight, tighten pocket then, be put in the freezer under humidity 85%-90%, the reserve temperature condition and preserve.
Preferably, in described step (1), the weight concentration of calcium chloride solution is 0.5%.
Preferably, in described step (2), the bright peach of harvesting in the freezer of 8 ℃ of temperature, humidity 85%-90% pre-cooled 12 hours;
Preferably, in described step (4), employed freshness protection package is that thickness is the nanometer bag of 0.045mm~0.06mm.
Preferably, in described step (3), the amount of described fresh-keeping agent for peach is 1.8% of the bright peach weight of adorning.
(3) beneficial effect
The advantage and the good effect of fresh-keeping agent for peach of the present invention are: can reduce peach respiratory intensity, postpone climacteric, delay ripening time, prolong storage period, compare with existing antistaling agent, freshness date can prolong 10~20 days.
Bright peach preservation method of the present invention has adopted fresh-keeping agent for peach of the present invention, sprays calcium chloride water and carry out pre-cooled processing before bright peach is adopted, and determines suitable reserve temperature according to bright peach freezing point simultaneously, is beneficial to prolong storage period.
