Problems solved by technology

[0010] From the above search, we know that due to the late start of research in this field in our country, there are not many reported achievements and patents.
At the same time, there are many types of shellfish. Due to the difference in geographical environment, the physiological metabolism of shellfish is different. It is difficult to meet the actual needs with a single method.
As one of the most economical shellfish in the South China Sea, there is no report on this aspect

Embodiment 1

[0026] 1. Purification of Phaphia rugosa: Select fresh and live Phaphia rugosa clams of the same individual size, put them in a frame and put them into a circulating seawater purification pool, and prepare sterile seawater with ultraviolet light at a temperature of 20-30°C, a ratio of 1:25 to 1:25, and a flow rate of 2.44 to circulate seawater. ×10 -5 m 3 / s (take the volume of purification bucket as 0.105m 3 For example, the same below), the purification treatment is 24h.

[0027] 2. Keeping the clam alive: add sterile seawater with a shell water ratio of 1:2~4 to keep it alive. The keeping container can be divided into shells weighing 1-5kg, sealed with a film, and carried out at 15-18°C. Keep alive and circulate.

[0028] Result: After purification, the shellfish meets the hygienic standard of seawater shellfish (GB2744-1996): coliform group ≤ 300MPN / 100g, total number of bacteria 5 cfu / g. The survival rate of shellfish reached 100% after 2 days of keeping alive in ice ...

Embodiment 2

[0030] 1. Purification of Phaphia rugosa: Select fresh and live Phaphia rugosa clams of the same individual size and put them into a frame for circulating seawater purification pool, and prepare sterile seawater with ultraviolet light at a temperature of 20-30°C, baby ratio water 1:15, and circulating seawater flow rate 3.66 ×10-5m3 / s, purification treatment 24h.

[0031] 2. Keeping the clam alive: Add sterile seawater with a shell water ratio of 1:2~4 to keep alive. The keep alive container can be divided into 1~5kg shellfish, sealed with a film, and carried out at 15~18°C. Keep alive and circulate.

[0032] Result: After purification, the shellfish meets the hygienic standard of seawater shellfish (GB2744-1996): coliform group 5 cfu / g. The survival rate of shellfish reached 100% after 2 days of keeping alive in ice temperature.

Embodiment 3

[0034] 1. Purification of Phaphia rugosa: Select fresh and live Phaphia rugosa clams of the same individual size, put them in a frame and put them into a circulating seawater purification pool, and prepare sterile seawater with ultraviolet light at a temperature of 20-30℃, baby ratio water 1:25, and circulating seawater flow rate 2.44 ×10 -5 m 3 / s, purification treatment 24h.

[0035]2. Keeping clams alive: take 1-5kg of clams, pack them with mesh belts, wrap them tightly with a sealing machine, and keep them alive at 10-15°C.

[0036] Result: After purification, the shellfish meets the hygienic standard of seawater shellfish (GB2744-1996): coliform group ≤ 300MPN / 100g, total number of bacteria 5 cfu / g. The survival rate of shellfish reached 100% after 2 days of keeping alive in ice temperature.

Abstract

The invention relates to a Paphia undulate ecological ice-temperature keeping-alive circulation method. The Paphia undulate is purified for 24 hours in germfree seawater prepared by ultraviolet sterilization. The factors such as temperature, seawater flowrate, shellfish-water ratio, etc. are controlled by taking the indexes of total number of bacteria and coliform group. After the purification isqualified, the shellfishes are subpackaged and then carried out the ecological ice-temperature keeping-alive circulation with water or without water. The invention combines the purification technology and the keeping-alive technology, which is simple and systemic, is fit for popularizing, thus not only solving the eating safety problem of the shellfish, but also solving the key problem that the Paphia undulate is difficult for keeping-alive circulation aiming at the biological metabolic characteristic of the specific shellfish in Hainan area.

Description

technical field [0001] The invention relates to a method for ecological ice temperature preservation and circulation of Paphia rugosa clams. Background technique [0002] The clam is mainly distributed in the coasts of Fujian, Guangdong and Guangxi in my country, and is an excellent species of shellfish cultured in the South China Sea. It is a filter-feeding organism. While filtering bait organisms, it will also accumulate intestinal pathogenic bacteria or harmful substances in the water. If it is not purified, it is likely to cause food poisoning incidents. The methods and technologies of shellfish purification mainly include shellfish temporary cultivation, sterilization by chlorine and chloride, ultraviolet sterilization and ozone sterilization, among which the use of ultraviolet radiation to treat seawater is the most commonly used method for shellfish purification. [0003] During the whole storage, transportation and sales process of shellfish after being caught and p...
