[0002] Food detection safety is an important means to ensure food safety. It involves the detection, evaluation, and control of harmful substances in food to protect public health. Food detection can promptly detect harmful substances in food, avoid foodborne diseases caused by food contamination, and safeguard the health and life safety of the public. During the food detection process, a food detection sample placement rack is required to store and keep the samples warm.
