1. Definition of food grade chemicals and industrial grade chemicals
Food grade chemicals refer to chemicals used in food processing and cooking, including acidity regulators, thickeners, nutritional fortifiers, preservatives, etc. Food grade chemicals refer to products that comply with food hygiene and safety standards and regulations, have stability and safety, and are used to protect or improve food quality.
Industrial grade chemicals refer to chemicals used in industrial production and other non food fields, such as purification agents, solvents, catalysts, petroleum additives, etc. Industrial grade chemicals are mainly used in industrial processing processes in non-human and animal fields, with the main purpose of providing materials and energy for production.
2.Quality standard differences
Food grade chemicals must comply with food regulations, standards, and regulations of various countries, and must not contain harmful substances to human health, such as heavy metals and toxic substances. They also need to be strictly controlled through various testing methods. The standards for industrial grade chemicals are relatively loose, and for some specific uses, there may be harmful components to the human body.
3. Usage differences
Food grade chemicals are mainly used in food processing and cooking, and can play a role in seasoning, preservation, protection, and enhancing their nutritional value. Industrial grade chemicals are mainly used in industrial production processes, such as petroleum processing, pharmaceuticals, cosmetics production, etc.
4.Manufacturing and sales differences
The manufacturing and sales of food grade chemicals usually require relevant certification and approval from national or local food and drug regulatory authorities. Sales are usually conducted through channels such as supermarkets and food processing factories. Industrial grade chemicals can usually be sold through chemical wholesalers, distributors, online stores, and even large supermarkets.
5.Security differences
The selection and processing technology of food grade chemicals generally require stricter requirements, and must not contain any harmful ingredients, which will not have a negative impact on human health. Industrial grade chemicals may contain harmful components or byproducts that are not suitable for food processing and cooking.
In summary, food grade chemicals and industrial grade chemicals are two different types of chemicals, with significant differences in quality standards, uses, manufacturing, and sales channels. Understanding these differences helps consumers choose and use chemicals correctly, thereby ensuring personal safety and health.
