Problems solved by technology

However, frozen golden pomfret requires high equipment conditions and complicated operation, while cold storage can be achieved only by an ice box, and does not require a lower storage temperature. Although some preservatives are currently used for cold preservation of golden pomfret, but , due to its unreasonable ratio, the shelf life is often short, and golden pomfret may cause secondary pollution of "smell". Fish is kept fresh, but still cannot get rid of the low temperature environment. For example, the antistaling agent in the scheme "A Method for Preserving Golden Pomfret" applied by the applicant of this patent on the same day has no obvious advantages in normal temperature conditions. Studies have found that adding sea duck egg white to the preservative formula can effectively improve the freshness of seafood; however, in continuous practice, it has been found that the use of sea duck eggs in the preservative will cause misjudgment by the electronic nose, resulting in the inability to effectively detect the freshness of golden pomfret

Embodiment 1

[0030] A non-damage online fresh-keeping method for golden pomfret. The method is: after killing the fresh golden pomfret, remove the viscera, soak in the cleaning solution for 3 minutes, remove it and put it in an ice box at -4°C After refrigerating for 30 minutes, soak in cleaning solution until the ice slag on the surface completely melts, then take out the fish and soak it in the preservative solution for 60 minutes, then put the fish in the refrigerator until the surface of the preservative layer hardens , and then wrap the fish body tightly with plastic wrap and keep the fish fresh at room temperature. During this period, samples are taken from time to time. The samples are distinguished by near-infrared analysis, and fresh and rotten golden pomfrets are stored separately.

[0031] The preparation method of the cleaning solution in this example is as follows: 7 parts by weight of sodium chloride, 13 parts of trehalose, 13 parts of tomato juice and 120 parts of water weigh...

Embodiment 2

[0038] An on-line fresh-keeping method for golden pomfret without damage, the method is: kill fresh golden pomfret, remove internal organs, soak in cleaning solution for 5 minutes, remove and put into ice box at 0°C Refrigerate, after refrigerating for 40 minutes, soak in cleaning solution until the ice slag on the surface completely melts, then take out the fish, put it directly in the preservative solution for 90 minutes, put the fish in the refrigerator until the surface of the preservative layer hardens, Then wrap the fish body tightly with plastic wrap and keep the fish fresh at room temperature. During this period, samples are taken from time to time. The samples are distinguished by near-infrared analysis, and fresh and rotten golden pomfrets are stored separately.

[0039] The preparation method of the cleaning solution in this example is as follows: 13 parts by weight of sodium chloride, 17 parts of trehalose, 17 parts of tomato juice and 150 parts of water weigh each ...

Embodiment 3

[0046] A non-damage online fresh-keeping method for golden pomfret, the method is: after killing the fresh golden pomfret, remove the viscera, soak in the cleaning solution for 4 minutes, remove it and put it in an ice box at -2°C Refrigerate, after refrigerating for 35 minutes, soak in the cleaning solution until the ice slag on the surface is completely melted, then take out the fish, put it directly into the preservative solution and soak for 80 minutes, then put the fish in the refrigerator until the surface of the preservative layer hardens , and then wrap the fish body tightly with plastic wrap and keep the fish fresh at room temperature. During this period, samples are taken from time to time. The samples are distinguished by near-infrared analysis, and fresh and rotten golden pomfrets are stored separately.

[0047] The preparation method of the cleaning solution in this example is as follows: weigh each raw material in parts by weight of 10 parts of sodium chloride, 15...

Abstract

The invention relates to the technical field of preservation of trachinotus ovatus, in particular to a damage-free online preservation method for trachinotus ovatus. The preservation method comprisesthe following steps: killing fresh living trachinotus ovatus, removing internal organs, cleaning the trachinotus ovatus in a cleaning solution, freezing the trachinotus ovatus in an ice box after cleaning, immediately soaking the trachinotus ovatus in a preservation solution after thawing, tightly wrapping the fish body with a preservative film, performing preservation at normal temperature, taking samples irregularly during the period, testing the freshness of the trachinotus ovatus by using a near infrared spectrometer so as to quickly distinguish whether the trachinotus ovatus is fresh or not, and storing the trachinotus ovatus separately. The method can achieve the normal-temperature preservation of the trachinotus ovatus, does not cause the secondary pollution to the trachinotus ovatus, does not damage the tissue of the trachinotus ovatus, is simple to operate, does not need sample processing and expensive instrument, and can quickly distinguish the meat quality of the trachinotusovatus.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of fresh-keeping golden pomfret, in particular to an online fresh-keeping method for golden pomfret without damage. [0003] 【Background technique】 [0004] Golden Pomfret (Trachinotus ovatus) scientific name is oval pomfret, local name is yellow waxy pomfret, golden pomfret, belongs to bony fish class, perciformes, trevalidae, pomfret genus. The body of this fish is flattened, oval, and the anal fin is slightly equal to the second dorsal fin, both of which are significantly longer than the abdomen. The head side is flat, the caudal peduncle is thin, and the body is covered with small round scales, which are not easy to peel off. The fish meat is white, tender, delicious, and rich in various nutrients and unsaturated fatty acids. It is one of the famous and valuable marine economic fish in the southern coast. At present, golden pomfret is mainly sold as frozen products for long-distance transportat...
