Problems solved by technology

[0003] The method of cooling is generally to use ice cubes or cold storage materials to control the temperature from the ecological critical temperature to the freezing point, so as to keep the aquatic products in a hibernating state for transportation. However, this method has a large temperature difference and high transportation costs. High, which affects the subsequent temporary maintenance of aquatic products
The method of chemical drug anesthesia refers to the use of sedative drugs to assist in the transportation of aquatic products. It refers to adding a certain concentration of related chemical drugs to the water body of aquatic product transportation. After chemical drugs enter the body of aquatic products, they can forcibly change the quality of aquatic products during transportation. The physiological state of aquatic products makes aquatic products enter a similar dormant state, unresponsive to the outside world, slow in action, and greatly reduced in activity. However, due to the use of chemical drugs such as anesthetics, there are bound to be potential risks to food safety, and the anesthesia time and recovery time are relatively long. , the amount of anesthetics used is difficult to control, expensive, and not suitable for the transportation of commercial fish

Embodiment 1

[0020] A method for transporting live aquatic products using dry ice, comprising the following steps:

[0021] S1. Add 20g of dry ice and 10L of transport water (clear water with a salinity of 13.8) to the living body transport box, close the lid, and fully dissolve the dry ice and transport water to form a high-concentration carbon dioxide solution;

[0022] S2. Put 50 fresh and alive Penaeus vannamei that need to be transported into the high-concentration carbon dioxide solution in the living transport box and soak for 1min, and the vannamei quickly enters a coma state;

[0023] S3. Add 10L of transport water (clear water with a salinity of 13.8) to the living body transport box, until the dosage of dry ice in the living body transport box is 1g / L, then add circular honeycomb activated carbon with a diameter of 10cm and keep it for 5min , to keep the vannamei in a semi-comatose state, and then it can be transported;

[0024] S4. During transportation, detect the dissolved o...

Abstract

The invention discloses a method for transporting living aquatic products by utilizing dry ice. The method comprises the following steps of S1, adding the dry ice and transportation water into a living body transportation box, and controlling the adding amount of the dry ice to be 2g/L-3g/L; S2, putting the fresh living aquatic products needing to be transported into the living body transportationbox to be soaked for 1-2 min; S3, adding a certain amount of transportation water into the living body transportation box till the adding amount of the dry ice in the living body transportation box is 1g/L-1.5g/L, and keeping for 5-10 min; and S4, in the transportation process, maintaining dissolved oxygen in the transportation water in the living body transportation box, at the moment, enablingthe aquatic products in the coma state to begin to be gradually recovered, and enabling the transportation time to be 3-8 h. The operation method is simple, the stress reaction of the aquatic productsis small, the anesthetic effect on the aquatic products is good, no food potential safety hazard exists, the transportation survival rate is high, and the transportation cost is low.

Description

technical field [0001] The invention relates to a method for transporting living aquatic products, in particular to a method for using dry ice to transport living aquatic products. Background technique [0002] With the increasing demand in the fresh market, the logistics and distribution of fresh aquatic products has become an important aspect of market competitiveness. At present, the distribution of fresh aquatic products in the same city is still based on the mode of aeration and oxygenation of oxygen bags or plastic boxes. There are also some improvements, such as the design of intelligent thermal insulation transport boxes to ensure the dissolved oxygen demand and Temperature control to reduce loss during transportation. In the process of live aquatic product transportation, cooling and chemical drug anesthesia are used to make the transported aquatic products in a semi-comatose state, reduce the metabolism of aquatic products, reduce the oxygen consumption and excret...
