Abstract
The invention discloses a kind of preservation methods of grape, and provide a kind of storage quality that can be improved grape, extend the method for the preservation and freshness grape of grape fresh-keeping phase.Medium well grape is picked, field heat is dispersed, picks out mechanical damage, pest and disease damage, rotten and inferior fruit, then, grape is put into freezer within 12 hours and carries out precooling treatment by control, and pre- temperature of ice house control is at 2 DEG C ± 0.5 DEG C；The grape of pre-cooled processing is packed into rigid container, is reloaded into the PE freshness protection package of 0.03-0.05mm thickness, tightens fresh-keeping sack immediately；After freshness protection package equipped with grape is carried out acclimatization to cold training 16 hours, then Icetemperature Storage under the conditions of -0.7 DEG C ± 0.5 DEG C.The two kinds of technology combinations of Icetemperature Storage and spontaneous controlled-atmosphere are used for the fresh-keeping of grape by the method for preservation and freshness grape of the invention, and freshness date was up to 38 days, and for healthy fruit up to 89.6%, the organoleptic quality and physical and chemical quality of grape are good.
Description
Technical field
The present invention relates to technical field of preservation of fresh, more particularly to a kind of preservation method of grape.
Background technique
Grape is delicious and tasty, and nutritive value is high, and sugar content is up to 10%-30% in mature berry, based on glucose,
Also contain mineral calcium, potassium, phosphorus, iron and multivitamin and a variety of amino acid, is one of favorite summer fruit of people, but
It is that grape belongs to berry fruits, thin skin succulence, water content is high, and grape is caused to be easy to happen in transport and storage
Mildew, threshing, brown stain, rot, dry branch phenomena such as and problem, seriously affect its commodity value and economic value.Since grape is easy
The features such as corruption and its production season, region, strange land transportation and sales, anti-corrosive fresh-keeping storing seem extremely important.
Summary of the invention
The purpose of the present invention is being directed to technical deficiency existing in the prior art, and provide a kind of storage that can be improved grape
Collection matter extends the method for the preservation and freshness grape of grape fresh-keeping phase.
The technical solution adopted to achieve the purpose of the present invention is:
A kind of preservation method of grape, which is characterized in that include the following steps:
(1) medium well grape is picked, field heat is dispersed, picks out mechanical damage, pest and disease damage, rotten and inferior fruit
It is real, then, grape is put into freezer in time and carries out precooling treatment, pre-coo time is 16 hours, pre- temperature of ice house control 2 DEG C ±
0.5℃；
(2) grape by pre-cooled processing is fitted into plastic casing, then the rigid container equipped with 500g-750g grape is packed into
With a thickness of in 0.03-0.05mm, the PE freshness protection package that bale capacity is 35cmx25cm, fresh-keeping sack is tightened immediately；
(3) after the freshness protection package by above-mentioned equipped with grape carries out acclimatization to cold training, the ice temperature under the conditions of -0.7 DEG C ± 0.5 DEG C
Storage；The temperature of ice house of the acclimatization to cold training is 0 DEG C ± 0.5 DEG C, and the acclimatization to cold training time is 16 hours.
Further, after the freshness protection package equipped with grape being put into plastic crate progress acclimatization to cold training in the step (3), and
Enter plastic crate neat code to carry out Icetemperature Storage on the library frame of ice Wen Ku.
Further, the time that grape freezer from picking to being put into carries out precooling treatment in the step (1) controls 12
Within hour.
Compared with prior art, the beneficial effects of the present invention are: the method for preservation and freshness grape of the invention stores ice temperature
Hiding is organically combined with two kinds of technologies of spontaneous controlled-atmosphere, and air conditioning technology has effectively delayed the decline of grape soluble solid content, had
Conducive to Icetemperature Storage；Again by Icetemperature Storage, the metabolism of grape is reduced to the maximum extent and effectively inhibits harmful microorganism
Growth, effectively kept the sense organ and physical and chemical quality of grape, extended shelf-life, made the freshness date of grape up to 38
It, healthy fruit is up to 89.6%；By selecting specific thicknesses PE bags and bale capacity, making to be formed in film packaging bag is suitable for that grape is exhaled
The gaseous environment of suction extends its shelf life to control the respiratory intensity of grape.
