Description
【Technical field】
The present invention relates to postharvest technology of fruits and vegetables field, and in particular to a kind of preservation method of cherry.
【Background technology】
Cherry also known as car li, Ying Tao etc., its is bright in colour, sparkling and crystal-clear beautiful, red as agate, Huang such as congealed fat, nutrition are special
Abundant, fruit is rich in the multiple elements such as sugar, protein, vitamin and calcium, iron, phosphorus, potassium, belongs to the high-grade product of fruit in the market
Kind, even in the busy season, its price is also up to more than 15 yuan/jin.Yet with cherry thin skin and water content height, damage of easily damaging,
And because its sugar content is very high, mycotic infection is highly susceptible to, causes to rot and lose commodity value, only may be used under normal temperature
Preserve 1-3 days.Therefore, how to extend the preservation and freshness time of cherry, keep nutritional ingredient to greatest extent, reduce rotting rate,
Key issue in being sold as Cherry Production.
At present, common preservation method has quick freezing and cold preserving, air conditioned storage, chemical coating, antiseptic medicine processing, radiation storage
Hide etc..For some of methods because cost is too high or condition limitation is difficult to promote, some are then because fresh-keeping effect is bad, it is difficult to reach
Satisfied preservation.
【The content of the invention】
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of preservation method of cherry.The present invention
Cherry preservation method can effectively extend the storage time of cherry and of good preservation effect.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of preservation method of cherry, comprises the following steps：
(1) the ripe cherries of 8-9 are harvested, and choose homogeneous size, no disease and pests harm, the cherry having no mechanical damage；
(2) cherry chosen is put into after soaking 2-3min in calcium chloride solution, pulls out and dry；
(3) cherry that calcium chloride treats is put into after soaking 3-4min in fresh-keeping liquid, pulls out and dry；The fresh-keeping liquid bag
Include the raw material components of following parts by weight：Wintergreen 3-7 parts, sessile alternanthera herb 2-5 parts, cloves 2-5 parts, fruit of a cubeb litsea tree 1-4 parts and viscid germander herb
1-2 parts；
(4) cherry for treating fresh-keeping liquid is immersed in film, after parcel is uniform, is pulled out and is dried；The film include with
The raw material components of lower parts by weight：Modification of chitosan 8-10 parts, Na-alginate 2-3 parts and sweet potato starch 0.5-1 parts；
(5) cherry after coating problems is fitted into polythene film bag and after tying, is put into freezer and refrigerates, you can.
Further, in step (2), the mass concentration of the calcium chloride solution is 0.8-1.2%.
Further, in step (3), the volume ratio of the cherry and the fresh-keeping liquid is 1：2-3.
Further, in step (3), the fresh-keeping liquid includes the raw material components of following parts by weight：6 parts of wintergreen, successively
Spend 4 parts, 4 parts of cloves, 1.5 parts of 2 parts of the fruit of a cubeb litsea tree and viscid germander herb.
Further, the fresh-keeping liquid is prepared by following methods：By weight, each raw material components are weighed；Will
The each raw material components weighed crush；It is the super of 20KHz with frequency after adding 300-400mL water into the crushed material
Sound wave extracts 30-35min, filtering, is concentrated into 120mL, obtains extracts of Chinese herbal medicine；The extracts of Chinese herbal medicine is added into sterilized water
It is 15-17mg/mL to be diluted to concentration, produces the fresh-keeping liquid.
Further, in step (4), the film is prepared by following methods：By weight, each raw material is weighed
Component；The modification of chitosan weighed is dissolved in the chitosan solution for being configured to that mass concentration is 2% in acetic acid solution, will be weighed
Good sodium alginate is soluble in water to be configured to the sodium alginate soln that mass concentration is 1.5%, and the sweet potato starch weighed is entered
Row is gelatinized to obtain gelatinized starch；After above-mentioned chitosan solution, Na-alginate solution and gelatinized starch are well mixed, glycerine is added,
After stirring 30-40min, you can obtain the film.
Further, in step (5), the gas concentration lwevel in the polythene film bag is less than 25%.
Further, in step (5), the temperature of the freezer is -1~-0.5 DEG C, humidity 90-95%.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
First, due to cherry thin skin cracky, therefore, first invention is first soaked using calcium chloride solution to improve the hard of cherry
Degree, to keep the integrality of cherry in follow-up preservation process；Second, immersion treatment is carried out to cherry using fresh-keeping liquid,
The fresh-keeping liquid of the present invention is prepared by natural Chinese herbal medicine, green safe, and wintergreen in Chinese herbal medicine, sessile alternanthera herb, cloves,
The fruit of a cubeb litsea tree and viscid germander herb synergy can strengthen antibacterial corrosion-resistant effect, wherein, it is prepared relative to one-component fresh-keeping
Liquid, fresh-keeping liquid of the invention improve 4-8% to the inhibiting rate of bread mold, and therefore, the fresh-keeping liquid using the present invention enters to strawberry
Row immersion treatment, it further enhancing resistivity of the strawberry to disease fungus；3rd, cherry is wrapped up using film
Processing, to form layer protecting film on cherry surface, it on the one hand can effectively slow down the metabolic activity of cherry, on the one hand can have
Effect reduces epidermis damage of the cherry in storage, transportation, so as to further extend the storage time of cherry and fresh-keeping effect
Fruit.To sum up, each fresh-keeping step interaction in preservation method of the present invention, the storage time of cherry and fresh-keeping can effectively be extended
Effect is good.
