Color Protectant Testing

Color protectants are substances that protect or enhance the color of food. The color protectant itself does not have color, but it can interact with the color substance in food, making it difficult to be decomposed and destroyed during food processing and preservation, thereby promoting the food show a good color.

The right amount of color protectants is conducive to maintaining and improving the nutritional value of food, and helps to extend the shelf life of food. However, the addition of excessive color protectants will cause damage to human health. For example, nitrites are commonly used as color protectants in meat products, which has acute poisoning and carcinogenic risks. Therefore, it is particularly important to improve food quality and ensure food safety to analyze the type, content and performance of color protectants in food through professional testing.

STEMart provides comprehensive color protectant testing services to ensure the rational use of color protectants, guarantee food safety, and make color protectants better serve the food processing industry.
