Detection of bacterial contamination in disinfectant during use

In order to ensure the quality of tableware detergent and establish effective market constraints, the National Quality Supervision and Administration Bureau will conduct random inspections of tableware detergent products on the market from time to time. Tableware detergent, as an important kitchen and washing product, is mainly composed of surfactants, secondary surfactants, and auxiliary ingredients in a certain formula. Therefore, the safety of tableware detergents for human health and the environment is the most concerning issue for relevant parties. Non toxic, non irritating, and highly biodegradable, it has always been a performance requirement for high-quality tableware detergent products. The products for random inspection of dishwashing detergents mainly include hand washing dishwashing detergents (including fruit and vegetable detergents), bottle cleaning agents for beverages, acidic cleaning agents for food tools and industrial equipment, alkaline cleaning agents for food tools and industrial equipment, machine washing dishwashing detergent products, and food industry detergents (including composite main agents). Hand washing dishware detergent (including fruit and vegetable cleaning agents) testing item 1. Total active matter content measurement 2. pH value measurement 3. Fluorescent whitening agent measurement 4. Methanol content measurement 5. Formaldehyde measurement 6. Arsenic measurement 7. Heavy metal content measurement 8. Total bacterial count measurement 9. Coliform group measurement beverage bottle cleaning agent testing item 1. Total active matter content measurement 2. Coliform group measurement 3. Fluorescent whitening agent measurement 4. Methanol content measurement 5. Formaldehyde measurement 6 Arsenic determination 7. Heavy metal content determination 8. Total bacterial count determination for acidic cleaning agents used in food tools and industrial equipment 1. Corrosion rate determination 2. Mass fraction determination of effective acids 3. Fluorescent whitening agent determination 4. Methanol content determination 5. Formaldehyde determination 6. Arsenic determination 7. Heavy metal content determination 8. Total bacterial count determination 9. Coliform group determination 10 Detection of phosphorus pentoxide content in alkaline cleaning agents for food tools and industrial equipment: 1. Detection of phosphorus pentoxide content: 2. Determination of total alkali mass fraction: 3. Fluorescent whitening agent: 4. Determination of methanol content: 5. Determination of formaldehyde content: 6. Determination of arsenic content: 7. Determination of heavy metal content: 8. Determination of total bacterial count: 9. Detection of coliform group: Detergent products for machine washing tableware and detergents for food industry (including composite main agents): 1 Determination of total active matter content 2. pH value 3. Fluorescent whitening agent 4. Methanol content 5. Formaldehyde content 6. Arsenic content 7. Heavy metal content 8. Total bacterial count 9 Coliform group determination and detection are based on the standard GB 14930.1-2015 National Food Safety Standard for Detergents GB/T 9985-2000 Hand Wash Dishes Detergents GB/T 24691-2009 Fruit and Vegetable Cleaning Agents QB/T 2967-2008 Bottle Cleaning Agents for Beverages QB/T 4313-2012 Acid Cleaning Agents for Food Tools and Industrial Equipment QB/T 4314-2012 Alkaline Cleaning Agents for Food Tools and Industrial Equipment
