Description
Technical field
The present invention relates to technical field of aquatic product preservation, and in particular to a kind of side for preventing from giving birth to shredded squid irradiation processing denaturation
Method.
Background technology
Squid contains abundant good protein, and squid would generally be processed into raw shredded squid to facilitate storage, food by people
With.It is general to pass through to pickle, dry the fresh keeping time that moisture etc. improves raw shredded squid, but this needs to be sought to lose the part of shredded squid
Foster material and flavor taste are that the microorganism in cost, and raw shredded squid easily makes shredded squid in illumination, temperature and humidity etc.
Under the influence of occur rotten, the color of shredded squid also can slowly become yellow, brown by white, have a strong impact on shredded squid product
Aesthetic quality and economic benefit.Irradiated targets shredded squid is also adopted by the prior art.
The irradiated targets of food are mainly food exposure in electronics, X-ray, gamma-radiation plasma type irradiation ray
Under, make radiation exposed material absorbing ray and produce ion, these ions can cause microorganism composition occur chemical reaction from
And the cytoactive of microorganism is destroyed, and microorganism is killed, reach the effect of food fresh-keeping.With the sterilization fresh method phase such as pickle
Than irradiation sterilization effect is more thorough, and fresh keeping time is long.But these ions be likely to each component in food for example fat,
Protein, amino acid etc. chemically react, and cause food to occur rotten or produce irradiation peculiar smell.
Chinese patent CN200610052309, a kind of additive for reducing irradiation smell of patent name, 2006 dates of application
December 27, disclose and a kind of the reduction spoke that 0.1% vitamin A and 0.1% vitamin E are constituted is respectively by mass fraction
According to the additive of taste, it is added in the food of irradiated preparation, aquatic products to reduce the peculiar smell that irradiation is produced.But this addition
Agent belongs to the remedial measure after irradiation, covers the irradiation peculiar smell of generation, it is impossible to fundamentally suppress the generation of irradiation smell.
The content of the invention
Can cause to be denatured or produce the problem of irradiation peculiar smell for raw shredded squid irradiated targets, it is an object of the invention to carry
Method for preventing from giving birth to shredded squid irradiation processing denaturation, can effectively suppress the composition radiation parameter such as protein, amino acid or fat
Under denaturation, suppress irradiation peculiar smell and produce, thoroughly kill the microorganism in raw shredded squid, extend fresh keeping time, improve economic effect
Benefit.
The present invention provides following technical scheme：
A kind of method for preventing from giving birth to shredded squid irradiation processing denaturation, comprises the following steps：
(1) head, internal organ and cartilage are removed after frozen squid is thawed and obtains squid fillet, then stirring decortication；
(2) aeration-drying squid fillet to water content is 15%~20%, and then squid fillet is placed in vacuum infiltration instrument, to
Anti- denaturing liquid is added in vacuum infiltration instrument to squid fillet vacuum infiltration；
(3) aeration-drying squid fillet again, is then fed into rolling in calender, and wire drawing is made squid in being re-fed into wire drawing machine
Silk；
(4) shredded squid is put into polypropylene film packaging bag, is then sealed to fresh-keeping gas is passed through in polypropylene film packaging bag；
(5) polypropylene film packaging bag is put into irradiation sterilization in the irradiation field of cobalt -60；
(6) polypropylene film packaging bag is vacuumized at 1~8 DEG C, polypropylene film packaging bag is then sealed into freezen protective.
As a modification of the present invention, 5~15 DEG C of ventilation temperature, 2~4m/s of rate of venting, anti-denaturation in step (2)
Liquid is 2~3 with the mass ratio of squid fillet:1.
Used as a modification of the present invention, anti-denaturing liquid is prepared from by following weight portion component described in step (2)：It is yellow
12~15 parts of a kind of reed mentioned in ancient books, 10~15 parts of the Radix Astragali, 6~12 parts of black soya bean, 8~12 parts of Chinese cassia tree, 6~8 parts of anise seed, 5~8 parts of garlic, rat-tail
Grass 8~10 parts, 10~15 parts of green tea, 0.8~1.5 part of protease inhibitors, 0.6~1 part of trehalose, 2~5 parts of vitamin A,
2~5 parts of vitamin E, 1.6~2.4 parts of citric acid, 0.2~0.6 part of TBHQ, 2~4 parts of egg, white wine 6~
8 parts, 500~600 parts of water.
Used as a modification of the present invention, the anti-denaturing liquid is prepared from through procedure below：By the root of large-flowered skullcap, the Radix Astragali, black soya bean,
Chinese cassia tree, anise seed and garlic are placed in water boils, and adds Salvia japonica, green tea to continue water at 60~70 DEG C and boil 30~45 points afterwards
Clock, filters after being cooled to 20~23 DEG C and filtrate is obtained, and is given birth to protease inhibitors, trehalose, vitamin E, dimension is added in filtrate
Plain A, citric acid, TBHQ, egg, white wine, are thoroughly mixed and are made anti-denaturing liquid.
As a modification of the present invention, 5~15 DEG C of ventilation temperature, 2~4m/s of rate of venting, shredded squid in step (3)
Dried water content is 25%~35%.
Used as a modification of the present invention, the fresh-keeping gas in step (4) is made up of nitrogen and carbon dioxide, wherein nitrogen with
The mol ratio of carbon dioxide is 1~3:1, the charge of fresh-keeping gas is the 30%~50% of polypropylene film packaging bag volume.
Used as a modification of the present invention, the irradiance method in step (5) is：Polypropylene film packaging bag is high apart from ground
50~60cm, apart from the 0.8~1.6m of irradiation bomb of cobalt -60,1.0~7.0kGy of irradiation dose, 3~10Gy/s of irradiance rate, irradiation is not
The uniformity is less than 1.2, and radiation environment temperature is 1~8 DEG C.
Used as a modification of the present invention, the cryogenic temperature in step (6) is -10~-1 DEG C.
Raw shredded squid drying and dehydrating is made raw squid by the method for preventing from giving birth to shredded squid irradiation processing denaturation of the invention first
Silk is in doughy state, and anti-denaturing liquid is then penetrated into the inside of raw shredded squid by the method for vacuum infiltration, makes anti-denaturation
Liquid saturation gives birth to the antioxygens such as Tea Polyphenols, scutelloside that the water cooking liquids such as shredded squid meat, the root of large-flowered skullcap, the Radix Astragali, black soya bean, Salvia japonica, green tea contain
Agent is mutual with VitAVitE, citric acid, TBHQ, protease inhibitors, trehalose, egg etc.
The oxidation resistance and change sexuality of collaboration, fat, protein and amino acid in the raw shredded squid of lifting etc., suppress fat, egg
The degenerative process under radiation parameter such as white matter, amino acid, it is to avoid the generation of irradiation peculiar smell.Simultaneously the root of large-flowered skullcap, Chinese cassia tree, anise seed,
Flavonoid substances that garlic etc. has etc. can suppress antibacterial generation, the irradiated targets effect of the raw shredded squid of reinforcing, Er Qiehuang
The fragrant pungent taste that a kind of reed mentioned in ancient books, Chinese cassia tree etc. have can shield the irradiation smell of faint presence, play a part of to reduce irradiation smell.When irradiating simultaneously
Raw shredded squid is placed in the polypropylene packing bag filled with the fresh-keeping gas being made up of carbon dioxide and nitrogen, can starvation suppression
The oxidation of fat etc., it is to avoid the generation of irradiation smell, and fresh keeping time is extended, enhance the effect of irradiated targets.
Beneficial effects of the present invention are as follows：
The method for preventing from giving birth to shredded squid irradiation processing denaturation of the invention, can by the anti-denaturing liquid of vacuum infiltration in raw shredded squid
With oxidation, the denaturation of the nutritional ingredient under radiation parameter such as protein, fat, amino acid in effective suppression irradiation, and suppress spoke
According to the generation of taste, and the irradiated targets effect of raw shredded squid is good, and fresh keeping time extension, economic benefit is improved.
