Excelitas Noble Light Japan Co., Ltd. will strengthen the sales of its BlueLight Steri-Belt system equipped with ultraviolet lamps to food processing factories in the Japanese market. Even after the outbreak of the COVID-19 pandemic, the demand for convenience and time-saving in meal preparation continues to rise across generations. The variety of frozen foods and frozen meats has expanded, and they are being utilized in various situations due to their long shelf life and the ability to stock up. On the other hand, in terms of food safety, there is an increasing demand for thorough hygiene management in the manufacturing processes at food processing factories, including the safety of raw materials. Hygiene management programs require that equipment in contact with food undergo appropriate cleaning, disinfection, and maintenance, with the frequency and management methods left to the discretion of each company. However, the common practice of cleaning and disinfecting several times a day may be insufficient in preventing microbiological cross-contamination (the transmission of pathogenic microorganisms between foods).
