Antioxidant Testing

Antioxidants are food additives that can prevent or delay the oxidation of food, improve the stability of food and extend the storage period. The correct use of antioxidants can not only extend the storage period of food to bring good economic benefits to producers and consumers, but also to ensure food safety. However, when excessive amounts of antioxidants are added to food, it may cause harm to human health. Therefore, it is necessary to ensure the quality and safety of food through food additive testing.

Antioxidant testing uses a series of physical and chemical technical means to conduct qualitative and quantitative analysis of antioxidants in food. Professional testing can help you understand the performance of antioxidants in food and discover potential safety risks, thereby guiding the optimization of production processes and ensuring that food meets relevant industry standards and regulations.

STEMart provides comprehensive antioxidant testing services to promote the rational use of antioxidants in food, ensure food safety and protect consumer health.
