Abstract
The invention discloses a preservation method of squid. The method includes the steps of washing, soaking, sterilizing, packaging and freeze-storing. According to the method, TCM (traditional Chinese medicine) sterilizing liquid made from mugwort, honeysuckle flower, common anemarrhena rhizome, capillary wormwood herb, tatarian aster root, dandelion, officinal magnolia bark and hawthorn is used to soak the squid to suppress surface bacteria thereof; ozone solution is then used for sterilization, and ozone of strong oxidizing property has good action of inhibiting spreading of microorganisms and killing germs during preservation; ozone ice is finally used for storage. The squid preserved by the method is fresh up to 25 days, the method features long preservation time, no chemical residue and greenness, and the nutrition, color and freshness of the squid can be kept well.
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 squid, belong to transportation fresh-retaining technical field.
Background technology
Squid belongs to cephalopod, because of delicious meat, low-heat, low fat and the features such as high protein enjoy liking of people.The squid just caught has transparent feel, and be ink-jet juice after dried up, its back adventitia is pitchy.Prolongation along with the time after death loses transparent feel, and epidermis presents russet, and muscle is hardening.Epidermis loses moisture content and becomes dry, and chromatophore expands, and body surface keeps russet; If be in moisture state, chromatophore shrinks the spot in black, until pigment disappears become white.Therefore, pile up placement with frozen water process or by fishery products, whitening process can be accelerated.But the impact of squid microorganism and self enzymatic activity, squid is very easily putrid and deteriorated.By the impact in season, the squid caught summer is than moisture few in the squid muscle of catching autumn, and its musculature does not have autumn squid tight, and add that temperature is high, bacterium easily breeds, therefore bacterium more easily to grow meat more easily putrid and deteriorated.
Based on the self-characteristic of above squid, its fresh-keeping work seems particularly important.But the Preservation Treatment of existing squid is all the methods adopting ice cube freezing, this kind of method generally can only fresh-keeping sale about 10 days, and the shelf-life is short, be unfavorable for long-distance transport and squid generally all reduces greatly the 5th of fresh-keeping and cold storage the day its color and luster, nutrition and freshness; Can add the fresh crystalline substance of squid wait polyphenoils for extending the fresh keeping time of Fresh squid, and this kind of material all contains chemical substance and has a certain impact to health tool.
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, better can keep the preservation method of the squid of the nutritional labeling of squid, color and luster and freshness without chemical residual.
For solving the problem, the present invention is achieved through the following technical solutions:
A preservation method for squid, comprises the following steps:
1) select fresh and alive squid, clean, cut capsule, put into salt solution and soak 3 ~ 10min, then clear water rinses 2 ~ 3 times repeatedly, drains the water, for subsequent use;
2) by step 1) squid after process is placed in Chinese medicine sterilizing liquid dipping 18 ~ 30min, and pull out, clear water then carries out sterilization treatment after rinsing; Wherein said Chinese medicine sterilizing liquid is made up of the component of following weight portion: wormwood 10 ~ 18 parts, honeysuckle 7 ~ 15 parts, the wind-weed 8 ~ 18 parts, oriental wormwood 5 ~ 12 parts, aster 2 ~ 8 parts, dandelion 8 ~ 15 parts, the bark of official magnolia 10 ~ 20 parts, hawthorn 1 ~ 8 part;
3) by step 2) process after squid pack, described in be packaged as vacuum packaging or controlled atmospheric packing;
4) by packaging after squid and Ozone Ice with the mass ratio of 1:4 ~ 6, the order spreading one deck Ozone Ice by one deck fish loads in foam insulation box, and at the Ozone Ice of topmost paving one deck, then foam insulation box to be sealed, chilled storage in the insulating box being placed in 0 ~ 7 DEG C.
In such scheme, further, step 2) in, described sterilization treatment can for the ozone water solution of 3 ~ 10mg/L concentration with 155 ~ 180mL/min flow velocity drip washing squid, 2 ~ 8min.
Further preferably, step 2) in, described sterilization treatment is with 50 ~ 90mL/min flow velocity drip washing squid, 8 ~ 15min with the ClO 2 solution of 70 ~ 90mg/L concentration.
In such scheme, further, step 3) in, described vacuum packaging can be packed for vacuumizing with polypropylene plastics pocket
Further preferably, step 3) in, described controlled atmospheric packing is for be filled with 100%CO with polypropylene plastics pocket
2or be filled with ozone gas.
Compared with prior art, beneficial effect of the present invention is:
The present invention first carries out impregnation process with the Chinese medicine sterilizing liquid be made up of wormwood, honeysuckle, the wind-weed, oriental wormwood, aster, dandelion, the bark of official magnolia and hawthorn to squid, to suppress the bacterium on squid top layer; And then carrying out sterilization treatment with ozone solution, ozone has strong oxidizing property, has well kill inhibitory action to the diffusion of microorganism and the growth of preservation and freshness process bacterium, finally adopts Ozone Ice to preserve.Squid fresh keeping time after this method Preservation Treatment can reach 25 days, have fresh keeping time long, without the feature of chemical residual, environmental protection, and better can keep the nutrition of squid, color and luster and freshness.

Experimental example
Get the fresh and alive squid 100kg that each index such as size, freshness is all the same, be equally divided into 5 groups, 1 to 4 group adopts the method for the present embodiment 1 ~ 4 to carry out Preservation Treatment respectively successively and is set to test group, and the 5th group adopts traditional preservation method to be set to control group, namely only have ice cubes cold to store.
Each index of the squid after the above-mentioned 5 groups of Preservation Treatment of Observe and measure: 1, the mensuration of moisture: adopt the GB5009.3-2010 mensuration of moisture " in the national food safety standard food "; 2, the mensuration of gross protein value: GB5009.5-2010 " mensuration of national food safety standard Protein in Food "; 3, the mensuration of total sugar content: GB9695.31-91; 4, the mensuration of fresh keeping time, result of the test is as following table 1:
| Total sugar content/% | Moisture/% | Crude protein content/% | Fresh keeping time/d | |
| Test group 1 | 0.15±0.03 | 79.11±0.02 | 15.81±0.65 | 27 |
| Test group 2 | 0.14±0.04 | 80.71±0.42 | 16.21±0.07 | 25 |
| Test group 3 | 0.13±0.07 | 80.93±0.51 | 14.95±0.24 | 30 |
| Test group 4 | 0.14±0.04 | 81.31±0.42 | 17.01±0.11 | 28 |
| Control group | 0.06±0.07 | 53.22±0.28 | 7.81±0.31 | 10 |
Table 1
Be not difficult to find out from the result of upper table 1, adopt the moisture of squid after the Preservation Treatment of this method, total sugar content, crude protein content and squid fresh keeping time all apparently higher than the squid index adopting traditional preservation method process, the nutrition of squid, quality and shelf-life are improved greatly, and the storage being more conducive to squid is sold and processing.
