1. Why is Retorting Essential for Canned Fish?

Canned fish is popular among consumers due to its practicality, convenience and diversity. How to ensure the food safety of canned fish, extend the shelf life of the product, maintain the good taste, color and texture of the product, and improve the product quality are the core issues that canned fish processing companies consider. The core of this process is sterilization and steaming. The canned fish is treated with high temperature and high pressure in the sterilizer to eliminate microorganisms and bacteria that are harmful to the human body. This article will reveal to you how canned fish is sterilized and what are the advantages.



The benefits of retorting process for canned fish:

Ensure food safety: The heat treatment of the autoclave can eliminate harmful microorganisms and viruses in canned fish, so the product can be eaten safely without refrigeration, which is convenient for storage and transportation.

Long shelf life: The sterilization kettle uses high temperature (usually around 121°C) and high-pressure environment to process canned fish, which can kill most bacteria and spores and prevent food spoilage. Through the above treatments, the shelf life of canned fish can be significantly extended, generally ranging from months to years.

Preservation of nutrients: The nutrients of canned fish can be preserved to the maximum extent through sterilization treatment at appropriate temperature and time. For example, you can try a lower sterilization temperature with a slightly longer time, or use graded sterilization technology, first sterilize at a lower temperature and then sterilize at a high temperature for a short time, to reduce the damage of nutrients to heat treatment.

Expand market coverage: Due to its long shelf life and easy transportation and storage, canned fish can be sold to more distant areas, including remote areas or areas lacking refrigeration facilities, expanding sales markets, for more information on retort machines, Click here now!

To ensure effective sterilization while retaining the texture and flavor of the canned fish.

• Pressure control: The autoclave operates at a pressure above atmospheric pressure, usually around 2-4 bars, to promote uniform heat penetration and maintain the integrity of the can.

• Real-time monitoring: Each batch of products is rigorously validated to confirm that the sterilization parameters are met. Continuous monitoring ensures uniform heat distribution throughout the sterilization process.

• Cooling and inspection: Cooling after cooking must be controlled to prevent deterioration during the cooling stage, and after cooling, it must be inspected for damage and deformation to prevent secondary contamination.
