1. Cleaning: Clean fresh soft-shelled turtle thoroughly with clean water to remove sediment and dirt. You can gently scrape the surface of the turtle with a brush to ensure thorough cleaning.
2. Boil: Boil a pot of water, and then put the turtle into the boiling water. Boiling for a period of time can ensure that the turtle is treated at high temperature both inside and outside, killing most bacteria and other harmful microorganisms. The cooking time can depend on the size and quantity of soft-shelled turtles, and usually 5- 10 minutes is enough.
3. Temperature treatment: after the soft-shelled turtle is cooked, it is soaked in high-temperature (above 85℃) water for a period of time to ensure that the internal temperature of the soft-shelled turtle meets the sterilization requirements. The time can be extended as required, generally 15-20 minutes.
4. Cooling: put the processed soft-shelled turtle into cold water for rapid cooling to avoid bacteria from reproducing again. Ensure that the soft-shelled turtle is completely cooled before carrying out other treatment steps.
The above steps can effectively kill most bacteria and harmful microorganisms, but can not guarantee the complete elimination of all microorganisms. If higher sterilization effect is needed, it is recommended to use special disinfectants or appliances and follow the product instructions.
In the process of sterilization, we must keep clean and hygienic, pay attention to personal protection, avoid cross-contamination of food and ensure food safety. If necessary, you can consult a professional food hygiene and safety agency for more detailed guidance.
