Embodiment 1

[0029] Select 2-3 years old, 2.1-3.3cm long market mud cockles, remove surface silt, dirt, remove dead shellfish, and purify shellfish microorganisms;

[0030] According to the shell water ratio of 1:6, the water change rate is 5 times / hour, the seawater temperature is controlled at 28°C, and the salinity is 26.2‰, so that the cockles can spit sand completely, and the microorganisms in the body can reach the standard of coliform bacteria ≤ 30MPN / 100g.

[0031] Purified shellfish are pre-cooled within 4 hours to close the shellfish.

[0032] Select individual cockles of uniform size, drain the surface water on sterilized gauze, put 40 cockles (volume about 0.18 liters) in each bag, and put them into a polyvinylidene chloride-polyester polyethylene compound with a size of 20cm×18cm. In the high-barrier retort bag, fill in about 0.54 liters of CO2, O2, N2 mixed gas with a volume ratio of 5:1:4, and seal the mouth of the bag.

[0033] Store the packaged cockles at 4°C, and the sh...

Embodiment 2

[0037] The clam pretreatment, purification, precooling and aeration are all the same as in Example 1.

[0038] The packaged cockles are stored at 0°C, and the shelf life is 17 days.

Embodiment 3

[0040] The clam pretreatment, purification, precooling and aeration are all the same as in Example 1.

[0041] The packaged cockles are stored at 10°C, and the shelf life is 7 days.

Abstract

The invention discloses a fresh-keeping method for bivalve shellfish marine products, which comprises pre-cooling bivalve shellfish marine products in 4 hours after cleaning and purifying bivalve shellfish marine products, gas-regulating packing CO2, O2, and N2 gas-regulating gas with the size ratio of 5:1:4 and refrigerating the package under the temperature of 0DEG C-10DEG C. The invention combines the gas regulating packing and the low-temperature storing, which can prolong the shelf life of living bodies of bivalve shellfish type evidently. The shelf lives of the bivalve shellfishes which are stored under 0DEG C, 4DEG C, 10DEG C by using the method of the invention are 17 days, 13 days and 7 days respectively. During the shelf preservation period, the bivalve shellfish type has better vitality and fresh degree. Compared with the traditional method, shelf lives are prolonged greatly, and the invention has the advantages of low investment, low cost, and wide adaptability.

Description

technical field [0001] The invention relates to the field of seafood storage, in particular to an anhydrous fresh-keeping and alive-keeping method for bivalve seafood. Background technique [0002] Bivalve molluscs belong to tidal flat economic molluscs, including cockles, razor clams, meretrix meretrix, etc. It is one of the popular seafood and an important part of human food. [0003] Bivalve shellfish seafood is not only nutritious and delicious, but also rich in taurine, which has health care functions for people of different ages, and is very popular among domestic and foreign consumers. Every year in my country, a large number of shellfish such as meretrix meretrix, Philippine clam and oyster are exported to all over the world, and they are one of the main export aquatic products in my country. [0004] The protein of bivalve meat is easily digested and absorbed by the human body, and has always been a source of cheap animal protein supply for people. For bivalve mol...
