The main application of high concentration ozone water machine in aquatic products
- 2020-08-03-

As a new disinfectant for aquatic products, ozone can disinfect and preserve aquatic products in three ways. There are currently three different methods: ozone water, ozone ice and ozone gas enhancement. Chlorine disinfection is a common disinfection of fresh fish, but it has great drawbacks. Chlorine disinfection has poor sterilization effect, residual, corrosion resistance, and environmental pollution.

The ozone water produced in the high-concentration ozone water machine has a strong oxidizing ability, and the sterilization effect is also very strong. Using a high-concentration ozone water machine for disinfection can greatly increase and reduce the number of original bacteria in our aquatic products, including for E. coli, Staphylococcus aureus and other bacteria and spores can extend its storage period.

Studies have found that the 15-minute post-treatment effect of yellow croaker with an ozone water concentration of 4.68 mg/L is better than other groups, and its storage period can be extended by 2 days. Poly Technology Guangzhou Liu ozone has a concentration of 10mg/L ozone water flowing out, which can extend the freshness for more than 3 days. The contact working time of ozone water is generally 10 seconds to 15 minutes. It varies according to the type of aquatic product.

The ozone water in the high-concentration ozone water machine is well used in the processing of squid, salmon, eel, flounder, octopus, tuna, mackerel, oyster, shellfish, seaweed, etc. Ozone water is frozen into ozone ice, and the ozone in the ozone ice is slowly released as the ice melts. In many inhibitions, ozone disinfection efficiency is excellent at low temperatures for bacteria in fish surface mucus, and the slow half-life characteristics make ozone ice particularly suitable for the preservation of aquatic products and transportation. Using it to preserve aquatic products can achieve a very good preservation effect.

The study found that when the ozone content is 5mg/kg, the total number of colonies in the test group is reduced by 82% compared with the control group during the preservation process of ozone ice fish flakes, Litopenaeus vannamei, Litopenaeus vannamei and tilapia. 97%, extending the shelf life of 3 products to 4 days.

Using ozone gas, we can improve the quality of sensory education and reduce the number of microorganisms. Using ozone water, ozone ice and ozone gas to process aquatic products can effectively reduce the number of original bacteria and extend the storage period.

Application in ozone water: rinse> flow> static immersion. Using ozone technology as a disinfectant for aquatic products in my country, not only can we effectively extend the preservation period, but also improve the color, taste, and taste of aquatic products; remove peculiar smells.

In aquatic products, any effect of nutrition is reasonable, not a process of increasing ozone in quality. In addition, after using ozone to treat aquatic products, it will be decomposed into oxygen without any harmful substances remaining, and will not directly affect human mental health. Therefore, ozone preservation will become a very important way for my country to develop aquatic product preservation.
