Embodiment 1

[0026] 1. Purification of corrugated clams: Select fresh and live clams with the same size and put them into the circulating seawater purification tank, prepare sterile seawater with ultraviolet temperature of 20-30 °C, 1:25 of Bebi water, and 2.44 of circulating seawater flow. ×10 -5 m 3 / s (with the volume of the purification barrel 0.105m 3 For example, the same below), purification treatment for 24h.

[0027] 2. Corrugated clams keep alive: add sterile seawater at a ratio of 1: 2 to 4 to water to keep alive, the keep alive container can be divided into shells weighing 1 to 5kg, sealed with film, and carried out at 15 to 18°C. Keep alive.

[0028] Results: The purified shellfish met the seawater shellfish sanitation standard (GB2744-1996): coliform group≤300MPN / 100g, total bacteria 5 cfu / g. The survival rate of the shellfish reached 100% after being kept alive at ice temperature for 2 days.

Embodiment 2

[0030] 1. Purification of corrugated clams: Select fresh and live clams with the same size and put them into the circulating seawater purification tank, prepare the sterile seawater with ultraviolet temperature of 20-30℃, beibei water 1:15, and circulating seawater flow rate of 3.66 ×10-5m3 / s, purification treatment for 24h.

[0031] 2. Corrugated clams keep alive: add sterile seawater at a ratio of 1: 2 to 4 to water to keep alive, the keep alive container can be divided into shells weighing 1 to 5kg, sealed with film, and carried out at 15 to 18°C. Keep alive.

[0032] Results: The purified shellfish met the seawater shellfish sanitation standard (GB2744-1996): coliform group≤300MPN / 100g, total bacteria 5 cfu / g. The survival rate of the shellfish reached 100% after being kept alive at ice temperature for 2 days.

Embodiment 3

[0034] 1. Purification of corrugated clams: Select fresh and live clams with the same size and put them into the circulating seawater purification tank, prepare sterile seawater with ultraviolet temperature of 20-30 °C, 1:25 of Bebi water, and 2.44 of circulating seawater flow. ×10 -5 m 3 / s, purification treatment for 24h.

[0035]2. Corrugated clams to keep alive: take 1~5kg of shellfish, pack them with mesh belt, wrap them tightly with a sealing machine, and keep alive and circulate at 10~15℃.

[0036] Results: The purified shellfish met the seawater shellfish sanitation standard (GB2744-1996): coliform group≤300MPN / 100g, total bacteria 5 cfu / g. The survival rate of the shellfish reached 100% after being kept alive at ice temperature for 2 days.

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 is qualified, 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 keeping alive and circulating the ecological ice temperature of the corrugated barfia clam. Background technique [0002] Corrugated clams are mainly distributed along the coasts of Fujian, Guangdong and Guangxi in my country, and are excellent varieties for shellfish culture in the South China Sea. It belongs to filter-feeding organisms. While filtering the bait organisms, it also accumulates intestinal pathogens or harmful substances in the water. If it is not purified, it is likely to cause food poisoning. The methods and technologies of shellfish purification mainly include temporary maintenance of shellfish, sterilization with chlorine and chloride, ultraviolet sterilization and ozone sterilization, among which the use of ultraviolet irradiation to treat seawater is the most commonly used method for shellfish purification. [0003] During the whole process of storage, transportation and sales of shellfish aft...
