Standard for Food Grade Gases

The standard of food grade gas mainly includes the following aspects:

high purity: Food-grade gases must have high purity to ensure product safety and quality. For example, food-grade carbon dioxide must be strictly controlled in terms of impurities and harmful components.

Non-toxic and harmless: food grade gas must be guaranteed to be non-toxic and harmless to human body, and can not contain any harmful ingredients to human health.

Compliance with relevant regulations: The production and use of food-grade gases must comply with relevant regulations and standards, such as food safety regulations, to ensure compliance.

Specific to different food-grade gases, such as food-grade oxygen and food-grade nitrogen, there are additional standards:

food grade oxygen: In addition to requiring high oxygen content percentage purity and no other toxic gases, it also requires colorless, odorless, less harmful impurities, and extremely low moisture content to avoid harm to the human body.

Food grade nitrogen: widely used in food packaging and preservation, requires high purity, no harmful gas impurities and other characteristics. In some baked goods, moon cakes and other inflatable packaging, filled with food grade nitrogen, in order to maintain the freshness of food and extend the shelf life.

In general, the standards for food-grade gases focus on purity, safety and compliance to ensure the safety and reliability of food-grade gases during food production and processing. Please note that the specific standards may vary by region and gas type, so local regulations and industry standards should be consulted in practical applications.
