The impact of temperature on the food industry, catering industry, cold chain transportation, and food sales industry is very important because temperature is one of the main factors affecting the growth and reproduction of microorganisms. Improper temperature control in the production environment may cause cross-contamination of products by microorganisms through the flow of people, logistics, and air, resulting in unqualified products. Improper transportation temperature control may change the sensory state of the product or even breed odor, leading to customer rejection or even fines and compensation. Improper control of the finished product storage process may accelerate abnormal changes in the physical and chemical indicators of the product and increase the risk of unqualified inspections.
