Technical Field

The invention relates to a method for preserving and transporting fresh and alive marine products, in particular to a method for temporarily breeding, packaging and transporting alive shrimps.

Background

The existing live shrimps are frozen and cultured in seawater for several days in the sale process as commodities, and the shrimps which can survive after being cultured in the seawater for several days can only be enjoyed by consumers in a near sea area or a distance sea area with short transportation time.

For consumers who are not near or at the source of production, such as remote inland areas away from the ocean, a luxury is created if fresh shrimp are consumed due to the transportation time and shrimp's environmental requirements; at present, live shrimps are sold or the fresh and alive characteristics of the live shrimps are ensured in a remote express mode, and no report is provided.

Because the growth habit of the live shrimps and the parameter values of the environment and the like required by the survival process of the live shrimps must be consistent with or very close to the original living environment of the live shrimps, the key point is to ensure the temporary culture technology and the living body transportation of the live shrimps.

3) and (3) transportation:

and determining to adopt air transportation or automobile transportation by express according to the distance of the destination.

Compared with the prior art, the method adopting the technical scheme has the advantages that the living environment is arranged, so that redundant substances in the intestines can be discharged after the live shrimps are replaced by the original seawater environment, the living space of the living body is restored in a pure physical mode, and the living characteristics of the living body in the delivery process such as express delivery can be realized within the transportation time of 3-15 days.

The preferred scheme adopted by the invention is as follows:

in the oxygen supply technology, a mode of supplying oxygen from the bottom of the storage pool is adopted.

The temporary culture process requires a pressure consistent with the primary storage environment, and the pressure is controlled by the amount of water or increased by the flow rate of water.

The live shrimp is selected from peeled shrimp.

The specific implementation mode is as follows:

the invention is described in detail below with reference to examples:

the temporary raising, packing and transporting method of live shrimp includes the following steps:

1) temporary culture:

the method comprises the following steps of (1) transporting the peeled shrimps from a raw water area production place and a water source in the same environment to a storage place to be sold, wherein shading treatment is needed in the transportation process, the temperature of the suitable living environment of the shrimps is 10-18 ℃, the pressure value is equivalent to the seawater pressure value (the pressure value is ensured by increasing the flow rate of water through supplying oxygen at any time) of 60 meters (0.6 MPa) in the transportation process, and the dissolved oxygen content is 5-8 mg/L; and (5) carrying out transportation in a dark place.

According to the original storage environment of the shrimps, the temporary culture capable of maintaining the production habit of the shrimps is carried out, the suitable living environment temperature of the shrimps is ensured to be 10-18 ℃, and the water in a storage pond generally passes throughThe drinking water is prepared by mixing the drinking water with instant sea crystal (commercially available as instant sea crystal, such as that produced by sea-water-Jia-sea Crystal Co., Ltd., Changyi) under stirring or specifically according to the specification of instant sea crystal, and ensuring that the salinity of water is 1.022 kg/m²(the value obtained by the salinity tester during the measurement) is consistent with the original environment or can adapt to the peeled shrimp, and the dissolved oxygen amount in the temporary culture process is 5 mg/L-8 mg/L; the pressure value of the water in the storage pool is consistent with the pressure value of the original marine living environment of the shrimps, about 60 meters deep (0.6 MPa), the pressure value is usually controlled by adopting a deeper temporary culture pool or controlling the pressure through the flow velocity of the water, the pressure is increased by the generated impact force in the process of the faster flow velocity of the water, and thus, the pressure consistent with the original environment of the seawater can be obtained through monitoring by an instrument.

The sound decibel number is the same as or similar to the original marine living environment of the shrimps and cannot exceed 45 decibels; in the oxygen supply process, a pool bottom oxygen supply mode is adopted, oxygen is supplied at any time, and the dissolved oxygen reaches 120 mg/L.

And adding 20-30 g of beneficial bacteria into the water per 1 cubic meter 2-3 hours before the pellithrix, and culturing the pellithus in the storage pond for more than 3 days. The beneficial bacteria are commercially available: water quality improving agents, for example: the strong effect exciting produced by Shandong Chenfeng company (product execution standard: Q/370703SSCF 014-2019). It is also necessary to add another commercially available beneficial bacterium: for example, the concentrated EM bacteria produced by Baino biological medicine science and technology limited of salt city can be put in according to the instruction book stand of the product in the actual putting amount; for example, about 0.3 to about 0.5 liters is required for a 1 cubic meter water source.

The addition of the two beneficial bacteria not only discharges the excess substances in the intestines of the peeled shrimps, but also is beneficial to the peeled shrimps to keep the fresh and alive processes without consuming the nutrition of the peeled shrimps and keep the meat plump without consuming weight; the temporary culture time is 2 days.

In the temporary cultivation process, temporary cultivation is carried out in a light-proof workshop or a pool body of a factory building.

2) Packaging:

determining the volume of the inner packaging bag according to the number of the shrimps, and sealing the water and the monomers in the storage pool into the inner packaging bag, wherein the compressive strength of the inner packaging bag is over 60MPa, and the inner packaging bag is subjected to sealed packaging by adopting transparent PVC for food; ensuring that the activity space of the peeled shrimp is more than 5 times of the volume of the monomer and the water amount is more than 4 times of the volume of the peeled shrimp; the dissolved oxygen is 5 mg/L-8 mg/L; the pressure of the water is consistent with the pressure of the original marine living environment of the live shrimps and is about 0.6 MPa.

The outer packing box is a high-strength foam packing box, the compression strength is more than 30MPa, the heat preservation temperature is 24-36 hours, and the temperature difference between the upper part and the lower part cannot exceed 5 ℃.

3) And (3) transportation:

and according to the distance of the destination, adopting express air transportation or automobile transportation. For example, if the distance exceeds 1000 km, an air transportation mode can be adopted, and if the distance is within 1000 km, an express delivery car transportation mode can be adopted.
