Description

Food coloring chemical inspection device

technical field

The utility model relates to the technical field of food inspection, in particular to a food coloring chemical inspection device.

Background technique

The color of food is an important factor for the sensory quality of food. People often use food colorings as food additives when making food. However, excessive food coloring will pose a threat to people's health. The pigment content is detected and controlled. In the detection process of food pigments, solvent extraction and filtration steps are required. The traditional chemical inspection of food pigments is separated from extraction and filtration, which not only has technical problems such as cumbersome operation process, inconvenient filtration, and inconvenient extraction, but also when testing pigments.
