Description
Technical field
The present invention relates to aquatic products technical field of preservation of fresh, especially relate to marine ice preservation antistaling agent of a kind of extra large shrimping and preparation method thereof, application.
Background technology
Sea shrimp body is little, moisture is high, musculature is soft, catch and treat that fishing boat returns port and generally needs 3 ~ 5d, at this moment had the part serious blackening of shrimp body of catching, especially 1 ~ 2d shrimp closely corruption of catching, edible quality and commodity value reduce greatly, but also obstruction affects fishing boat working days further, directly affects productivity effect.
The preservation method at current extra large shrimping sea mainly contains cold sea water preservation, preservation by partial and ice preservation, wherein cold sea water preservation be carry out in the pure seawater extra large shrimping being dipped in about 0 DEG C fresh-keeping, shrimp body can be made directly not contact with the oxygen in air, prevent black change, but the long-time immersion in water of shrimp body can be expanded, build deliquescing poor flexibility, quality appearance is poor, is only suitable for processing peeled shrimp product; Preservation by partial can make shrimp body substantially be in micro-ly to freeze state, can the breeding of anti-bacteria and the activity of tyrosinase in various degree, but can not suppress completely shrimp Ti ?become, and preservation by partial cost is high, be not suitable for the needs of mass transit, application remains in certain difficulty; Ice preservation is that preservation on the rocks of casing is carried out in extra large shrimping, its because of cost low, and the needs of suitable mass transit, it is still one sea shrimping preservation method the most conventional at present, but the fresh keeping time of ice preservation is short, maximum duration is 5 days, and easily causes shrimp body dewater and cause quality to decline.Therefore, the fresh keeping time and the fresh-keeping effect that improve extra large shrimping ice preservation seem particularly important.
Summary of the invention
The present invention is that the fresh keeping time of extra large shrimping ice preservation in order to solve prior art is short, and the problem easily causing shrimp body to dewater and cause quality to decline, provide a kind of scientific formulation reasonable, cost is low, there is excellent antibacterial, fresh-keeping and anti-black change effect, freshness date when can extending extra large shrimping ice preservation and the extra large shrimping sea ice preservation antistaling agent of shrimp body quality better.
Present invention also offers the preparation method of the marine ice preservation antistaling agent of a kind of extra large shrimping, preparation process is simple, and equipment investment is few, and cost is low, is applicable to large-scale industrial production.
To achieve these goals, the present invention is by the following technical solutions:
The marine ice preservation antistaling agent of a kind of extra large shrimping, be made up of the component of following mass percent: 0.5 ~ 1% glucose oxidase, 1 ~ 3% glucose, 10 ~ 15% dithiothreitol (DTT)s, 0.75 ~ 1% nisin, 20 ~ 30% casein sodiums, 3 ~ 5% metallothioneins, 20 ~ 30% fumaric acid sodiums, surplus is Rosmarinic acid.Antistaling agent prescription of the present invention is scientific and reasonable, each component is easy to get, cost is low, wherein, glucose oxidase plays deoxidation, and the oxygen under the effect of glucose oxidase around shrimp body can react with glucose and remove, be conducive to suppressing Xia Ti ?become, glucose also can maintain color and the gloss of shrimp body, is conducive to improving exterior quality; The metal ion (copper core) of the rapid chelating tyrosinase activity point position of dithiothreitol (DTT) energy, reaches the object suppressing enzymatic ?to become; Nisin has very excellent biocidal property, and security is good, can extend the freshness date of shrimp body; Rosmarinic acid can suppress the activity of various metabolic enzyme in shrimp body, delays the putrid and deteriorated of shrimp, and in addition, Rosmarinic acid also has bacteriostasis, and with nisin coordinated, fungistatic effect improves greatly; Casein sodium can improve retentiveness and the stability of shrimp body, the components such as the lipid in shrimp, moisture and musculature can also be combined securely, form compact texture, to reduce the loss of moisture, nutriment and flavor substance in preserving process, efficiently solve extra large shrimping and easily dewater at ice preservation process Prawn body and the problem causing quality to decline; Metallothionein has very strong demetalization ability, especially have very strong selective to copper ion, with dithiothreitol (DTT) coordinated, the activity of the thorough restraint of tyrosinase of energy, suppress black change successful, in addition metallothionein can reduce the accumulation of oxygen in shrimp body, impels bis-phenol to be transformed into colourless compound, thus suppress further Xia Ti ?become; Fumaric acid sodium plays the effect of the black change of antioxygen chemoprevention.The mutual Synergistic of each component in antistaling agent of the present invention, has excellent antibacterial, fresh-keeping and anti-black change effect, can extend the freshness date of shrimp and shrimp body quality better, have broad application prospects.
The preparation method of the marine ice preservation antistaling agent of a kind of extra large shrimping, key step is: after taking glucose oxidase, glucose, dithiothreitol (DTT), nisin, casein sodium, metallothionein, fumaric acid sodium and Rosmarinic acid respectively by said ratio, each component mixed.Mix after each component being weighed by proportioning and can obtain antistaling agent of the present invention, preparation process is simple, and equipment investment is few, and cost is low, is applicable to large-scale industrial production.
The application of the marine ice preservation antistaling agent of a kind of extra large shrimping when extra large shrimping is marine fresh-keeping.
Therefore, the present invention has following beneficial effect: (1) provides the marine ice preservation antistaling agent of a kind of extra large shrimping, scientific formulation is reasonable, cost is low, by the mutual Synergistic of each component, there is excellent antibacterial, fresh-keeping and anti-black change effect, the freshness date of shrimp can be extended and shrimp body quality better, efficiently solve the problem that the short and extra large shrimping of the fresh keeping time of extra large shrimping ice preservation is easily dewatered at ice preservation process Prawn body and caused quality to decline, have broad application prospects;
(2) mix after each component being weighed by proportioning and can obtain antistaling agent of the present invention, preparation process is simple, and equipment investment is few, and cost is low, is applicable to large-scale industrial production.
