Description
Technical field
The present invention relates to aquatic products technical field of preservation of fresh, more particularly, to a kind of red shrimp antistaling agent and preparation method thereof.
Background technology
Red shrimp, the entitled Solenocera Melantho of Latin are distributed widely in China the East China Sea and the Yellow Sea south and the South Sea, are
The Dominant variety of Offshore of Zhejiang Province resource, especially in the Zhejiang central and north, yield is higher.Because it has natural pink shrimp shell, meat
Delicate smooth, fresh fragrance U.S., and rich in protein and a variety of nutriments, there is very high food therapy value, human body can be enhanced
Immunity, therefore either appearance or meat, are obtained for the high praise energetically of consumers in general.
Treat that fishing boat returns the time generally 3 ~ 5d of need at port after red shrimp capture, in addition the catching season of red shrimp is summer and autumn, temperature
It is higher, and red shrimp moisture is high, thus in transportational process red shrimp Ji Yi become and rot, for slow down the Tui Se of red shrimp become with
And it is rotten, at sea most common preservation method is to carry out preservation on the rocks of casing to extra large shrimping in transportational process at present（That is iced storage
It is fresh-keeping）, ice preservation is at low cost, and suitable for the needs of mass transit, but ice preservation still remains following deficiency：（1）
Fresh keeping time is short, and maximum duration is 5 days, and easily causes the dehydration of shrimp body and cause quality decline；（2）The carapace of red shrimp is larger,
Ice preservation easily causes the cephalothorax onychoptosis of red shrimp, influences exterior quality；（3）Shrimp shell colour fading is caused to whiten, exterior quality is significantly
It reduces.Therefore, the fresh keeping time and fresh-keeping effect for improving red shrimp ice preservation are just particularly important.
Application publication number CN103948139A, data of publication of application 2014.07.30, a kind of entitled inhibition prawn blacking
A kind of antistaling agent for inhibiting prawn blacking is disclosed in the Chinese patent of antistaling agent and its preservation method, the antistaling agent, this is fresh-keeping
Agent is composed of the following components by mass percentage：0.2% ~ 0.9% erythrothioneine, 0.3% ~ 0.9% kelp polyphenol, 0.3% ~ 1%
Laminarin, 0.6% ~ 1% glacial acetic acid, surplus is water.The antistaling agent has the following disadvantages：Erythrothioneine is turned into antioxygen
With anti-blacking principle is：Erythrothioneine can inhibit tyrosinase catalysis leuco-compounds single phenol, its own can be used as substrate excellent
It is aoxidized prior to leuco-compounds single phenol, substrate is reduced by the amount of tyrosinase oxidation generation atrament, inhibition so as to reach
The purpose of prawn blacking, but its activity without inherently inhibiting tyrosine so that shrimp body still can there are a degree of
become, using effect is not good enough；Secondly, added with glacial acetic acid in the antistaling agent, the addition of glacial acetic acid can influence the flavor of prawn；Separately
Outside, the component in the antistaling agent is of high cost, should not promote；The colour fading of red shrimp and coming off for carapace cannot effectively be inhibited.
The content of the invention
The present invention is poor in order to solve the Preserving Reagent Freshening Effect of the prior art, and effect is single, it is impossible to effectively inhibit red shrimp
Colour fading, dehydration and the problem of coming off of carapace, it is reasonable to provide a kind of scientific formulation, at low cost, can inhibit red simultaneously
Shrimp is faded, becomes, putrid and deteriorated and cephalothorax onychoptosis, can extend red shrimp fresh keeping time, red shrimp antistaling agent of good preservation effect.
The invention also discloses a kind of preparation methods of red shrimp antistaling agent, and preparation process is simple, and equipment investment is few, cost
It is low, it is suitble to large-scale industrial production.
To achieve these goals, the present invention uses following technical scheme：
A kind of red shrimp antistaling agent, is made of the component of following mass percent：0.01 ~ 0.03% glucose oxidase, 1 ~ 3%
Glucose, 0.3 ~ 0.5% dithiothreitol (DTT), 0.03 ~ 0.05% nisin, 0.5 ~ 1% casein sodium, 0.01 ~ 0.05%
Modified Nano SiO2, 0.02 ~ 0.05% monoglyceride, 1 ~ 2% chitosan, 0.05 ~ 0.1% metallothionein, 3 ~ 5% Rosmarinic acids are remaining
Measure the acetic acid aqueous solution for being 0.5 ~ 1% for mass percent concentration.The antistaling agent of the present invention is a kind of coating antistaling agent, formula section
It is reasonable to learn, and each component is easy to get, at low cost, and wherein film forming agent is chitosan, but chitosan solution is not easy to be evenly affixed to red shrimp
Body surface and form the homogeneous protective film of thickness, film forming is poor, and permeability rate is unstable after forming a film, resistance oxygen water preventing ability, obdurability
It is poor with moisture retention, fresh-keeping effect is influenced, therefore modified Nano SiO is added in the present invention2It solves the above problems with monoglyceride,
Modified Nano SiO2Good dispersion, film forming can be improved, and no cracking phenomenon generates after forming a film, and can also improve chitosan film
Anti-microbial property and mechanical performance, and the resistance oxygen block-water performance of chitosan film can be significantly improved；Monoglyceride can improve modified Nano
SiO2And the dispersing uniformity of other components, and the mobility of the present invention can be improved, chitosan solution is enable uniformly to be attached to
Red shrimp body surface forms protective film in uniform thickness, moreover it is possible to further improve the water-retaining property of film, and can improve the transparency of film, favorably
In the exterior quality for improving red shrimp；Glucose oxidase plays deoxidation, under the action of the glucose oxidase around red shrimp
Oxygen can react with glucose removing, be conducive to inhibit Xia Ti become, glucose can also maintain the color and light of red shrimp
Pool is conducive to improve exterior quality；Dithiothreitol (DTT) can chelate rapidly the metal ion of tyrosinase activity point position（Copper core）, reach
To inhibit Mei Cu become purpose；Nisin has very excellent biocidal property, and security is good, can extend red shrimp
Freshness date；Rosmarinic acid can inhibit the activity of various metabolic enzymes in shrimp body, delay the putrid and deteriorated of red shrimp, in addition, Rosmarinic acid
Also there is bacteriostasis, with nisin coordinated, fungistatic effect greatly improves, it is most important that, Rosmarinic acid tool
There is anti-oxidant, fixation, can effectively prevent the oxidation and colour fading of pigment in red shrimp, be conducive to improve the sense organ product of red shrimp
Matter；Casein sodium can improve the retentiveness and stability of shrimp body, moreover it is possible to by components and muscle groups such as lipid, the moisture in shrimp
It knits and is firmly combined together, compact texture is formed, to reduce moisture in preserving process, nutriment and the stream of flavor substance
It loses, efficiently solves red shrimp and cause asking for quality decline in ice preservation process Prawn body easily dehydration and cephalothorax onychoptosis
Topic；Metallothionein has very strong demetalization ability, especially has very strong selectivity to copper ion, with dithiothreitol (DTT)
Coordinated can thoroughly inhibit the activity of tyrosinase, and so as to thoroughly inhibit blacking, metallothionein can be reduced in shrimp body in addition
The accumulation of oxygen promotes bis-phenol to be transformed into colourless compound, so as to further inhibit Hong Xia become；Acetic acid aqueous solution is as molten
Agent, to ensure that each component can quickly and completely dissolve.Each component is mutually synergistic in the antistaling agent of the present invention, has excellent
Antibacterial, fresh-keeping, color protection, anti-blacking effect can inhibit the colour fading of red shrimp simultaneously, becomes, putrid and deteriorated and cephalothorax onychoptosis, energy
Extend red shrimp fresh keeping time, and the quality of red shrimp is good, has broad application prospects.
