With the increasing concern for food safety and health, the choice of food-grade rubber seals has become particularly important. This article will explore how to correctly select food grade rubber seals and evaluate their safety to ensure safety and hygiene in the food production process.
Key factors in choosing food grade rubber seals:
Material safety: Food-grade rubber seals must be made of materials that meet international food safety standards, such as FDA (US Food and Drug Administration) certified materials, to ensure that harmful substances will not be released into the food.
Temperature resistance: the sealing ring should have good high and low temperature resistance, and can withstand the use of different temperature conditions in the food processing process.
Chemical resistance: For equipment in contact with different food raw materials and cleaning agents, the sealing ring should have good chemical resistance and is not easy to expand, deform or crack under the influence of food ingredients or cleaning agents.
Mechanical properties: The sealing ring should have good elasticity and wear resistance to ensure that long-term use will not be damaged or loosened due to pressure or movement.
Safety assessment of food-grade rubber seals:
Certification and standards: Ensure that rubber seals comply with international food safety certification standards, such as FDA 21 CFR Part 177, EU Regulation (EC) No. 1935/2004, etc. These certification standards guarantee that the material will not release toxic substances or odors when it comes into contact with food.
Supply chain transparency: Select suppliers with high supply chain transparency that can provide information such as raw material sources, production process control and product testing reports to ensure product quality control.
Food contact test: Before the actual application, the simulated test of contact with food is carried out to evaluate the stability and safety of the seal under different conditions to ensure that it does not pose a potential threat to food quality and health.
In summary, the selection and evaluation of food-grade rubber seals is an important step to ensure the safety of food production. Through reasonable selection and strict safety assessment, the risk of rubber seals in the food production process can be effectively reduced to protect the health and food safety of consumers.
