Abstract
The invention discloses a fresh-keeping method of prawn. The fresh-keeping method comprises the steps of selecting, washing, sterilizing, packing and freezing for storage. The method comprises the following steps of soaking the prawn in a traditional Chinese medicine preservative prepared from thyme, litsea cubeba, wormwood, rhizoma anemarrhenae, oriental wormwood, dried alum, radix sophorae flavescentis and fructus cnidii, and killing the bacteria on the surface of the prawn; boxing the prawn in a sterile environment, introducing nitrogen, and finally freezing the prawn at a low temperature. The prawn treated in the fresh-keeping method is remarkably improved in nutrients, appearance and taste compared with prawn treated in the traditional fresh-keeping method; moreover, the traditional Chinese medicine preservative adopted in the method is safe, non-toxic and free from chemical residue.
Description
Technical field
The present invention relates to a kind of health-care method of marine product, be specifically related to the preservation method of a kind of prawn, belong to seafood transportation fresh-retaining technical field.
Background technology
Prawn, is mainly distributed in Chinese Bohai and Yellow Seas, and northern East China Sea also has a small amount of distribution, is Chinese main shrimps in culture.Prawn is nutritious, and its meat is soft, easy to digest, in poor health and need the people taken good care of to be fabulous food after being ill.Containing abundant magnesium in prawn, magnesium has important regulating action to cardiomotility, well can protect cardiovascular system; it can reduce blood cholesterol level; prevent artery sclerosis, simultaneously can also coronary artery dilator, be conducive to preventing hypertension and myocardial infarction.Prawn is also rich in phosphorus, calcium, especially has help effect to children's, pregnant woman.Prawn because of nutritious, taste is fresh and tender and extensively like by consumer, but prawn fishing for, transport, be easy to be subject in process the invasion of bacterium and dead rotten.Prawn after death, not only appearance blackout, affects sense organ, and nutrient loss, and mouthfeel degradation, causes consumption figure degradation, greatly cause the wasting of resources, makes the every field such as the cultivation of prawn, transport, sale all be subject to great impact.
As methods such as chemical preservative storages, all there is many defects in traditional seafood store method.Although it is effective that chemical preservative stores method, but easily residue on food, chemical preservative is constantly accumulated in after human body acquires a certain degree, human cell DNA can be damaged, cell is made to follow the string gradually, easy generation relaxes, and human defense's ability also can be caused to decline, compromise the health of people.Chinese herbal medicine has had long use history in China, and Chinese herbal medicine has multiple medical value, and part Chinese herbal medicine has sterilization, anti-corrosion function, not only favorable anti-corrosion effect, but also safety non-toxic.Chinese herbal medicine is used as food preservative, not only can avoids the toxic hazard of chemical preservative, but also can the local flavor of retaining food product uniqueness, be a kind of new type natural anticorrisive agent with bright prospects.At present, there is no a kind of Chinese herbal medicine and cook anticorrisive agent to carry out the fresh-keeping method of prawn.
Summary of the invention
For above-mentioned deficiency, it is long that technical problem to be solved by this invention is to provide a kind of fresh keeping time, safety non-toxic and can keep the preservation method of the outward appearance of prawn, nutritional labeling and mouthfeel preferably.
For solving the problem, the present invention is achieved through the following technical solutions: the preservation method of a kind of prawn, comprises the following steps:
1) select fresh and alive prawn, reject the individuality of death, mutilation, variable color, for subsequent use;
2) the prawn aseptic water washing will chosen, puts into the freezing 5 ~ 10min of trash ice, shrimp is suffered a shock, for subsequent use;
3) by through step 2) prawn that processes puts into Chinese medicine anticorrisive agent and soaks 3 ~ 5min, take out, then drain in 5 ~ 7min in gnotobasis, for subsequent use;
4) in gnotobasis by through step 3) prawn that processes puts into sterile board, be then filled with sterile nitrogen, sealing, carries out accumulating under 1 ~ 3 DEG C of environment.
In such scheme, further, step 3) described Chinese medicine anticorrisive agent is made up of the component of following weight portion: thyme 5 ~ 10 parts, 2 ~ 5 parts, the fruit of a cubeb litsea tree, wormwood 10 ~ 15 parts, the wind-weed 6 ~ 10 parts, oriental wormwood 3 ~ 15 parts, alumen 1 ~ 5 part, kuh-seng 2 ~ 8 parts, frutus cnidii 6 ~ 12 parts.
In such scheme, further preferably, step 4) described in sterile board be made up of polyethylene material.
Compared with prior art, beneficial effect of the present invention is:
The present invention first processes prawn with the Chinese medicine anticorrisive agent that thyme, the fruit of a cubeb litsea tree, wormwood, the wind-weed, oriental wormwood, alumen, kuh-seng and frutus cnidii are made, and kills the bacterium on prawn; Then case in gnotobasis, be filled with sterile nitrogen; Finally can store under 1 ~ 3 DEG C of environment.Adopt the prawn that method provided by the invention is fresh-keeping, no matter nutritional labeling, outward appearance, or mouthfeel, all increase significantly than traditional preservation method, and the anticorrisive agent adopted is made up of natural Chinese herbal medicine anticorrisive agent, safety non-toxic, without chemical residual.
