Abstract
The invention belongs to the technical field of storage and preservation of agricultural products, and particularly discloses a controlled atmosphere low-temperature preservation method for fresh ginseng. The controlled atmosphere low-temperature preservation method comprises the following steps of: harvesting ginsengs; sorting; casing; pre-cooling; and performing controlled atmosphere preservation and the like. The ginsengs are pre-cooled to 0-4 DEG C, are warehoused in batches and are irradiated by using laser of 450-500 nm to have antibacterial and insecticidal effects. The parameters in a controlled atmosphere store are controlled in the way that the temperature is 2+/-0.5 DEG C, the humidity is 90+/-5 percent, the concentration of O2 is 13-15 percent and the concentration of CO2 is 2-5 percent. By controlling the key technology, the ginsengs are subjected to controlled atmosphere storage and preservation. The technical problem that the fresh ginsengs cannot be stored for long time is solved, the fresh ginsengs can be stored for over 6-7 months, have sufficient starch and high hardness, do not rot and are low in natural loss, good commercial quality is kept, the ginsengs are consumed out of season, the application range of the ginsengs is expanded, the added value of the ginsengs is increased, and higher economic benefit is achieved.
Description
Technical field
The present invention relates to a kind of Chinese medicine, agricultural products storage and preservation technology, promptly a kind of fresh ginseng controlled atmosphere low-temp antistaling method.
Background technology
In the prior art, genseng (
Panax ginsengC.A.Meyer) be the araliaceae ginseng plant, reinforce vital energy,, promote the production of body fluid that the function with intelligence development of calming the nerves is a kind of rare traditional Chinese medicine of strengthening by means of tonics, is known as " kings of hundred grass " admittedly take off.The grower is called garden ginsent, and wild survivor is called wild ginseng.More than excavating autumn, clean.Garden ginsent is called sun-dried ginseng through drying or drying; After steaming, dry or dry, be called red ginseng.Genseng contains ginsenoside, volatile oil, phenols, peptide constituents.Ginsenoside, polysaccharide, monose, amino acid, etc. multiplely have a characteristic active component, the quality of genseng quality depends on the number and the ratio of total saponin(e and each monomer saponin content.The of short duration picking season of genseng has restricted genseng processing with edible.With the genseng is other industry of raw material; Like industry such as medicine, health food, household chemicals; These industry will further develop, and just necessarily require the genseng storage and freshness-retaining technology to be the basis, otherwise the development of genseng processing cause will be restricted to a certain extent.The Along with people's growth in the living standard; Traditional salted, sugaring, drying, canning etc. can not have been satisfied the needs of people's life; People prefer the edible FF that keeps original quality and local flavor, still along with the enhancing of consumer health's consciousness, the Food Chemistry anticorrisive agent are more and more worried; So occurred utilizing physical method anticorrosion, thereby improved the security of food.
To the fresh-keeping research of genseng seldom, change like humiture in the single research controlled atmosphere storage at present, single research controlled atmosphere gas componant is formed or the like, and effect is very not remarkable sometimes.And be confined to the control of single factors in the controlled atmosphere such as gas composition, freshness date is still short partially.If gas componant in the controlled atmosphere process is formed, reserve temperature, humidity control, preliminary treatment (temperature of precooling and laser radiation) combines, and fresh-keeping effect is preferably arranged.
The genseng storage practice mainly is after the aquatic foods ginseng is processed into sun-dried ginseng and red ginseng at present, storage under drying condition.The present invention combines method of temperature that fresh ginseng is carried out preservation and freshness with controlled atmosphere, thereby has prolonged the freshness date of genseng, for the fresh-keeping technical foundation of raw-material storing has been established in the processing and the application of genseng.
Summary of the invention
The objective of the invention is to provide a kind of fresh ginseng controlled atmosphere low-temp antistaling method of good refreshing effect to above-mentioned deficiency.
Technical solution of the present invention is: a kind of fresh ginseng controlled atmosphere low-temp antistaling method, and its step is following:
(1) pre-treatment of fresh ginseng: after genseng is pre-chilled to 0～4 ℃, in batches go into air-conditioned cold store again, with 450～500nm laser radiation;
(2) air-conditioned cold store parameter control: 2 ± 0.5 ℃ of controlled atmosphere storehouse temperatures, humidity 90 ± 5%, 0
2Concentration 13%～15%, C0
2Concentration 2%～5%.Genseng rest period respiration extremely a little less than, oxygen content is controlled at 13%～15% and helps carrying out aerobic respiration, when oxygen content was extremely low, the storage genseng carried out anaerobic respiration and causes becoming sour of genseng etc., influences the quality of genseng.
Advantage of the present invention is: 1, can only be with the present situation of its dry product Long-term Storage to existing genseng; The storage practice of a kind of fresh ginseng is provided; Solved the technical problem that fresh ginseng can not Long-term Storage; Fresh ginseng can be preserved more than 6～7 months, make fresh ginseng slurry gas foot, hardness big, without putrefaction, natural wastage are low.2, oxygen content rationally is controlled at 13%～15%, helps carrying out aerobic respiration, avoids causing becoming sour of genseng, has guaranteed the quality of genseng.3, can keep good marketing quality, anti-season consumption with the scope of application of widening genseng, increases the genseng high added value, obtains higher economic benefit.
To combine embodiment that embodiment of the present invention is described in further detail below.
The specific embodiment
A kind of fresh ginseng controlled atmosphere low-temp antistaling method, its step is following:
1. gather: gather in withering period at genseng, ensure the quality of genseng.
2. selection: remove rot ginseng, disease and pest ginseng, vanning.
3. precooling: fresh ginseng is pre-chilled to 0～4 ℃, in batches warehouse-in.
The warehouse-in: when fresh ginseng is cased the warehouse-in amount with 450～500nm laser radiation. to play the effect of bacteriostasis and kill insects, help prolonging storage period.
5. air-conditioned cold store intrinsic parameter control: 2 ± 0.5 ℃ of temperature, should avoid temperature fluctuation to surpass 0.5 ℃; Humidity 90 ± 5% should be avoided the fluctuation of humidity; O
2Concentration 13%～15%, CO
2Concentration 2%～5 %, preserve after 180 days, storage back fresh ginseng outward appearance and inherent quality are all good, and very high commodity value is arranged.Fresh-keeping, antibacterial, the purpose avoiding moisture loss, prolong the fresh-retaining preserving phase of fresh ginseng have been realized.
Claims (1)
1. fresh ginseng controlled atmosphere low-temp antistaling method is characterized in that step is following:
