Abstract
The present invention relates to a fresh-keeping method for fresh eating medlar. The method comprises: picking fresh fruits with the carpopodium, carrying out pre-cooling, and storing by a fresh-keeping film. According to the present invention, the fresh medlar fruits treated by the method of the present invention can be stored for a long time, the keeping time is 6-8 months, the good fruit rate of the medlar can be maintained to more than 95%, the appearance and the internal components of the treated fruit are the same as the appearance and the internal components of the fresh medlar, the fruit is fresh, the carpopodium is green; the fresh-keeping method of the present invention has characteristics of low cost, convenient operation and practical technology, and can be used for long-term storage and long-distance transportation of the fresh eating medlar.
Description
Technical field
The present invention relates to the real preservation method of a kind of plant fresh fruit, specifically relate to a kind of matrimony vine preservation method of eating raw.
Background technology
Matrimony vine (Lycium chinense) is a kind of plant of integration of drinking and medicinal herbs, and fruit not only can be eaten raw but also can make dried being used as medicine, and is a kind of good tonic food.Big quantity research through scientist proves the protein, vitamin, amino acid and a large amount of, the micro-mineral element that contain needed by human body in the matrimony vine.Along with the separating of bioactive ingredients such as distinctive LBP-X, beta carotene and unrighted acid in the FRUCTUS LYCII, extraction and evaluation, the integration of drinking and medicinal herbs property of matrimony vine is highlighted more.
Along with the raising of living standards of the people, the matrimony vine with medicine-food two-purpose effect enjoys shows appreciation for somebody, and cultivated area also constantly enlarges, and according to statistics, China's matrimony vine in this year cultivated area reaches more than 100 ten thousand mu.In recent years, though the develop rapidly of matrimony vine industry, its storage technique of adopting the back fresh fruit is blank always, and the harvesting back is mainly preserved with the form of dry fruit and circulated.The unicity of its product has restricted the benign development of matrimony vine industry, and extensive processing mode, has also had a strong impact on quality and the safety of matrimony vine.Medlar fresh fruit is because of processes such as the airing that does not have dried fruit of lycium barbarum, oven dry, immersions, and function factor can not be destroyed, and is easily absorbed by the body again, has high nutritive value.All understanding matrimony vine the consumer of China 98% is first-class excellent tonic product, and 90% consumer does not see fresh matrimony vine simultaneously, does not more taste unique flavour of medlar fresh fruit.Reason is that medlar fresh fruit is the little berry of succulence, and skin approaches succulence, and sugar content is high, the preservation and freshness difficulty, can't transport for long-distance.Therefore the exploitation of medlar fresh fruit preservation and freshness new technology must help promoting the development of matrimony vine industry, improves the peasant economy benefit, satisfies the consumption demand that the people improve day by day.
Carry out antistaling fresh wolfberry fruit with PE preservative film package combination CT2 antistaling agent and do not see research report and production application.
Summary of the invention
The objective of the invention is for provide a kind of good refreshing effect, long fresh-keeping period, cost low eat the matrimony vine preservation method raw; Solve the undesirable storing difficulty that causes of present antistaling fresh wolfberry fruit effect, squeeze into domestic and international fruit market for the fresh fruit matrimony vine a kind of new method is provided.
A kind of matrimony vine preservation method of eating raw of the present invention is realized according to following steps:
A kind of matrimony vine preservation method of eating raw comprises and plucks band handle fresh fruit, precooling, preservative film storage, it is characterized in that it comprises following step:
1, plucks:, select in spite of wound fresh fruit and pick out the food grade of packing into material pallet, every dish 1～3kg at the band handle medlar fresh fruit of fine upper and lower noon harvesting 7～9 maturity of no dew;
2, precooling: the medlar fresh fruit of above-mentioned harvesting is put into-3～1 ℃ freezer or case in 1～5h, the alcohol with 30～50% soaks fruit 1～5 min, dries up precooling 12～24h in-3～1 ℃ of freezer cold wind again, makes the matrimony vine temperature reach 0～1 ℃;
3, preservative film storage: 16 ~ 30 μ m that the medlar fresh fruit after the above-mentioned precooling put into State Agricultural Product Preserving Technology Research Center's production are thick; In the PE preservative film of length 100 ~ 120 cm * width 50 ~ 80 cm specifications; Each film loading amount 1～2kg; Put into CT2 antistaling agent for grape (national agricultural products fresh-keeping Engineering Technical Research Centre provides) with the amount of 1 ~ 2 bag per jin again, with the preservative film seal package, place-3 ~ 2 ℃ freezer storage to get final product.
Advantage of the present invention is: but the medlar fresh fruit long preservation, and freshness date 6 ~ 8 months can keep matrimony vine fruit rate more than 95% well; Its outward appearance is identical with new fresh fructus lycii with inherent composition, and fruit is fresh, and carpopodium is emerald green; It is low that the present invention eats matrimony vine preservation method cost raw; Easy and simple to handle, technical application can be used for eating raw Long-term Storage and the long-distance transport of matrimony vine.
