Problems solved by technology

At the same time, because live aquatic products need to undergo metabolism during transportation, consume oxygen continuously, and discharge a large amount of metabolites, resulting in a large number of bacteria in the water body, which seriously threatens the transportation of live aquatic products, seriously threatens the survival of living aquatic products, and affects the safety of transportation. Survival rate
[0004] At present, the common fresh-keeping methods for living snails are: 1. Put the snails directly in the water. This method is likely to cause hypoxia in the water, and the metabolites of the snails are directly discharged in the water, causing bacteria to grow and easily causing the death of the snails. , the freshness of the living body is short, and the survival rate is low; 2: Separate the snail from the water, add ice and refrigerate for transportation. Although this method is convenient for transportation, the freshness of the snail is short, and the low temperature is easy to destroy the original snail. Taste

Embodiment 1

[0019] The living fresh-keeping method of snail is characterized in that, comprises the following steps:

[0020] 1) Snail pretreatment: Screen the live snails, remove the dead and broken shells, and then put them in clean water for 1 day; after washing with running water, put the live snails at a concentration of 3.5mg Immerse in an ozone solution of / L for 30min;

[0021] 2) Preparation of fresh water: first take clear water and put it in a sedimentation tank to stand for 5 hours, then filter to remove the sediment, then put it into a heating device and boil for 5 minutes, after cooling, refrigerate at -10°C to obtain fresh water for later use;

[0022] 3) Preparation of packing box: such as figure 1 As shown, the packaging box includes a box body 1 and a box cover 4. The inner chamber of the box body 1 is divided into three chambers by two partitions 2 with holes, and the middle chamber is a storage bin 7 for placing live snails. , the chambers on both sides of the storag...

Embodiment 2

[0025] The live preservation method of snails comprises the following steps:

[0026] 1) Snail pretreatment: Screen live snails, remove dead and broken shells, and then put them in clean water for 1 day; after washing with running water, put live snails at a concentration of 8mg / Immerse in L of ozone solution for 15min;

[0027] 2) Preparation of fresh water: first take clear water and put it in a sedimentation tank to stand for 5 hours, then filter to remove the sediment, then put it into a heating device and boil for 3 minutes, after cooling, refrigerate at 0°C to obtain fresh water for later use;

[0028] 3) Preparation of packing box: such as figure 1 As shown, the packaging box includes a box body 1 and a box cover 4. The inner chamber of the box body 1 is divided into three chambers by two partitions 2 with holes, and the middle chamber is a storage bin 7 for placing live snails. , the chambers on both sides of the storage bin 7 are filter bins 8 for filtering impurit...

Embodiment 3

[0031] The live preservation method of snails comprises the following steps:

[0032] 1) Snail pretreatment: Screen live snails, remove dead and broken shells, and then put them in clean water for 2 days; after washing with running water, put live snails at a concentration of 6 mg / Immerse in L of ozone solution for 20min;

[0033] 2) Preparation of fresh water: first take clear water and put it in a sedimentation tank to stand for 7 hours, then filter to remove the sediment, then put it into a heating device and boil for 4 minutes, after cooling, refrigerate at -4°C to obtain fresh water for later use;

[0034] 3) Preparation of packing box: such as figure 1 As shown, the packaging box includes a box body 1 and a box cover 4. The inner chamber of the box body 1 is divided into three chambers by two partitions 2 with holes, and the middle chamber is a storage bin 7 for placing live snails. , the chambers on both sides of the storage bin 7 are filter bins 8 for filtering impu...

Abstract

The invention discloses a fresh keeping method of living bodies of paphia undulata. According to the fresh keeping method disclosed by the invention, a broad-spectrum high-efficiency rapid green ozone solution is adopted for performing bactericidal treatment on the paphia undulata, disinfecting fresh keeping water used in the process of storing and transporting the paphia undulata, and reducing the introduction of other sundry funguses. In addition, the structure of a packaging box for storing and transporting the living bodies is specially designed, the packaging box is divided into three chambers, and a water pump is arranged, so that the circulating flow of water in the packaging box is realized, the requirements of the paphia undulata for oxygen are ensured, and oxygenates do not need to be additionally added; a filter screen can effectively filter metabolism trash produced by the paphia undulata in the transportation process and maintain the normal living environment of the paphia undulata, and the fresh keeping time of the living bodies of the paphia undulata is furthest prolonged. Compared with the prior art, the fresh keeping method disclosed by the invention has the advantages that the fresh keeping survival rate is high, the fresh keeping time is long, the operating method is simple, the shelf life of the paphia undulata can be effectively prolonged, the economic value of the paphia undulata is increased, and the popularization of the fresh keeping method is facilitated.

Description

technical field [0001] The invention relates to a fresh-keeping method for seafood, in particular to a fresh-keeping method for living snails. Background technique [0002] The snail is a kind of shellfish with a smooth shell surface, light tan, and dark brown water wavy lines. Because its shell has water wave lines, it is also known as "corrugated Bafei clam" and "oil snail". The meat of the snail is tender, delicious, rich in zinc and other trace elements, and has high nutritional value. It is known as the "milk" of the sea and is suitable for eating from east to west, from north to south, from men, women and children. [0003] In recent years, with the continuous improvement of living standards, people's requirements for food quality have become higher and higher, and the consumer groups of snails have also expanded rapidly. The snail is a kind of organism with water as the dominant factor. If it is out of the water for a long time, it will lead to death. The appearance ...
