The formaldehyde rapid detector can quickly and quantitatively detect the content of formaldehyde in various foods. The instrument reserves other detection programs and ports, and can easily add detection items according to future needs. In the future, it can be upgraded to a comprehensive type of instrument for detecting aquatic products, meat products, and noodle products. Food quality and safety refer to the provision of food that meets and safeguards the health needs of the population in terms of nutrition and hygiene. Food quality and safety involve issues such as food contamination, whether it is toxic, whether additives exceed standards, and whether labeling is standardized. Measures need to be taken before the food is contaminated to prevent contamination and the invasion of major hazardous factors.
