Description
Technical field
The present invention relates to aquatic products technical field of preservation of fresh, more particularly, to a kind of extra large shrimping sea ice preservation antistaling agent and
Its preparation method, application.
Background technology
Sea shrimp body is small, and moisture is high, and musculature is softer, and capture treats that fishing boat returns port and generally needs 3 ~ 5d, at this moment
The serious blackening of shrimp body through there is part to capture, the shrimp of especially first 1 ~ 2d captures is closely corrupt, and edible quality and commodity value are big
It is big to reduce, but also hinder further to influence fishing boat working days, directly affect productivity effect.
The preservation method at sea shrimping sea mainly has cold sea water preservation, preservation by partial and ice preservation, wherein Mare Frigoris at present
It is to be dipped in extra large shrimping in 0 DEG C or so of pure seawater to carry out fresh-keeping that water is fresh-keeping, can connect the not direct oxygen with air of shrimp body
It touches, prevents blacking, but shrimp body impregnates can expand in water for a long time, build softening poor flexibility, quality appearance is poor, is only suitable for
Process peeled shrimp product；Preservation by partial can make shrimp body be substantially at micro- jelly state, the breeding that can be inhibited bacteria in various degree and junket ammonia
The activity of sour enzyme, but cannot completely inhibit shrimp Ti become, and preservation by partial is of high cost, is not suitable for the needs of mass transit,
Using still having certain difficulty；Ice preservation is that extra large shrimping is carried out preservation on the rocks of casing, because at low cost, and suitable for big rule
The needs of mould transport are still presently the most a kind of common extra large shrimping preservation method, but the fresh keeping time of ice preservation is short,
Maximum duration is 5 days, and easily causes the dehydration of shrimp body and cause quality decline.Therefore, improve extra large shrimping ice preservation it is fresh-keeping when
Between and fresh-keeping effect be particularly important.
The content of the invention
The present invention is short in order to solve the fresh keeping time of the extra large shrimping ice preservation of the prior art, and easily causes the dehydration of shrimp body
And the problem of causing quality decline, it is reasonable to provide a kind of scientific formulation, at low cost, has excellent antibacterial, fresh-keeping and anti-black
Change acts on, and the freshness date and the good extra large shrimping sea ice preservation of shrimp body quality when can extending sea shrimping ice preservation are with fresh-keeping
Agent.
The present invention also provides a kind of preparation methods of extra large shrimping sea ice preservation antistaling agent, and preparation process is simple,
Equipment investment is few, at low cost, is suitble to large-scale industrial production.
To achieve these goals, the present invention uses following technical scheme：
A kind of sea shrimping sea ice preservation antistaling agent, is made of the component of following mass percent：0.5 ~ 1% grape
Carbohydrate oxidase, 1 ~ 3% glucose, 10 ~ 15% dithiothreitol (DTT)s, 0.75 ~ 1% nisin, 20 ~ 30% casein sodiums, 3 ~
5% metallothionein, 20 ~ 30% fumaric acid sodiums, surplus are Rosmarinic acid.The antistaling agent prescription of the present invention is scientific and reasonable, each component
It is easy to get, it is at low cost, wherein, glucose oxidase plays deoxidation, the oxygen under the action of the glucose oxidase around shrimp body
Gas can react removing with glucose, be conducive to inhibit Xia Ti become, glucose can also maintain the color and gloss of shrimp body, have
Beneficial to improvement exterior quality；Dithiothreitol (DTT) can chelate rapidly the metal ion of tyrosinase activity point position（Copper core）, reach suppression
Mei Cu processed become purpose；Nisin has very excellent biocidal property, and security is good, can extend the fresh-keeping of shrimp body
Phase；Rosmarinic acid can inhibit the activity of various metabolic enzymes in shrimp body, delay the putrid and deteriorated of shrimp, in addition, Rosmarinic acid also has
Bacteriostasis, with nisin coordinated, fungistatic effect greatly improves；Casein sodium can improve the retentiveness of shrimp body
And stability, moreover it is possible to the components such as lipid, the moisture in shrimp and musculature are firmly combined together, form fine and close knot
Structure to reduce moisture in preserving process, nutriment and the loss of flavor substance, efficiently solves extra large shrimping in ice preservation mistake
The problem of journey Prawn body is easily dehydrated and causes quality decline；Metallothionein has very strong demetalization ability, especially to copper
Ion has very strong selectivity, with dithiothreitol (DTT) coordinated, can thoroughly inhibit the activity of tyrosinase, inhibit blacking effect
Fruit is apparent, and metallothionein can reduce the accumulation of oxygen in shrimp body in addition, and bis-phenol is promoted to be transformed into colourless compound, so as into one
Step inhibit Xia Ti become；Fumaric acid sodium plays the role of antioxygen chemoprevention blacking.Each component mutually cooperates in the antistaling agent of the present invention
Synergy has excellent antibacterial, fresh-keeping and anti-blacking effect, and it is good to extend freshness date and the shrimp body quality of shrimp, with wide
Application prospect.
A kind of preparation method of sea shrimping sea ice preservation antistaling agent, mainly comprises the following steps：Claim respectively by said ratio
Take glucose oxidase, glucose, dithiothreitol (DTT), nisin, casein sodium, metallothionein, fumaric acid sodium
After Rosmarinic acid, each component is uniformly mixed.It is uniformly mixed after each component is weighed by proportioning and can obtain the present invention
Antistaling agent, preparation process is simple, and equipment investment is few, at low cost, be suitble to large-scale industrial production.
A kind of application of sea shrimping sea ice preservation antistaling agent when extra large shrimping is marine fresh-keeping.
Therefore, the present invention has the advantages that：（1）A kind of extra large shrimping sea ice preservation antistaling agent is provided,
Scientific formulation is reasonable, at low cost, mutually synergistic by each component, has excellent antibacterial, fresh-keeping and anti-blacking effect, energy
Extend the freshness date of shrimp and shrimp body quality is good, the fresh keeping time for efficiently solving extra large shrimping ice preservation is short and extra large shrimping is in ice
The problem of hiding the easily dehydration of preservation process Prawn body and causing quality decline, has broad application prospects；
（2）The antistaling agent that can obtain the present invention is uniformly mixed after each component is weighed by proportioning, preparation process is simple, if
Standby small investment, it is at low cost, it is suitble to large-scale industrial production.
