Colorant Testing

Colorant is a commonly used additive in food processing, also called food pigment. Its main function is to color food or improve food color. Appropriate amount of colorant can be metabolized by human body after consumption. When the colorant intake is too large and exceeds the load of human organs, it will accumulate in the human body and cause certain damage to the kidney. Therefore, it is necessary to ensure the quality and safety of food through colorant testing.

Colorant testing uses a series of physical and chemical technical means to analyze the performance and content of colorants in food and guide the rational use of colorants. Professional colorant testing can help companies choose appropriate colorants to improve food quality and avoid safety hazards, thereby promoting the launch and sales of food and supporting the healthy development of the industry.
