The reddish color of fermented tofu cannot be determined solely by its appearance; sampling and testing are necessary, and the abnormal product must be isolated. Relying solely on disinfectants is insufficient; equipment and the workshop environment must be thoroughly investigated. Air disinfection requires unmanned operation and material isolation. Disinfectants should be used according to specifications, and problems should be identified through a combination of production records and testing.

AB cleaning agents in food factories are prone to producing odor residues; Chlorine dioxide disinfectant can sterilize and deodorize without harmful residues. It can be diluted and used for disinfection of workshop equipment and water bodies, with matching ratios and safety operation requirements.

Chlorine dioxide disinfection in food production will produce harmful residues, and the water consumption of traditional large water washing is serious. Four measures can be taken to save water and reduce waste on the basis of ensuring food safety, so as to help enterprises achieve multiple benefits and win-win results.

While switching from sodium hypochlorite to chlorine dioxide disinfection offers advantages such as sterilization, biofilm removal, and fewer disinfection byproducts, the strong oxidizing properties of chlorine dioxide necessitate careful consideration of production line material compatibility: 316L stainless steel should be prioritized for piping, and fluororubber or polytetrafluoroethylene (PTFE) should be used for seals, while also considering the suitability of accessories such as sight glasses and spray nozzles. The switch can be smoothly completed in three steps: establishing material records, conducting a 72-hour immersion test, and carrying out small-scale trial runs and inspections, thus preventing equipment corrosion and damage.

Traditional chlorine dioxide disinfection in food factories is time-consuming and reduces production capacity. Addressing pain points such as solution preparation, spraying, and ventilation monitoring, the process can be optimized in stages through equipment upgrades, zoned disinfection, scientific control of disinfection parameters, and accelerated ventilation monitoring. This phased process optimization, while ensuring safety and compliance, can shorten disinfection time by 30-50%, freeing up production capacity and improving hygiene management.

Powdered milk powder and starch dust in the powdered food workshop will absorb and consume chlorine dioxide dry fog, reducing the disinfection effect. It can solve the disinfection problems caused by dust and ensure food safety by reducing dust before disinfection, regulating the particle size of dry fog, pulse releasing agent, optimizing the air flow in the workshop, and matching other disinfection methods.

Chlorine dioxide is widely used for disinfection in water supply and food supply chains, but current issues exist regarding standards, procedures, and residue monitoring. It is necessary to standardize operating procedures, establish a comprehensive residue monitoring system, and improve risk warning and emergency response mechanisms to ensure disinfection safety from water treatment plant to table.

When using chlorine dioxide for disinfection of chocolate equipment, it is necessary to control the residue of the agent to avoid damaging the flavor and quality of the product. The preparation of the agent should be standardized, the disinfection and rinsing process optimized, and residue compliance verified through multiple methods. Since chocolate is a low-moisture food, a customized cleaning plan needs to be developed based on the specific equipment to balance safety and production stability.

The strong oxidizing properties of chlorine dioxide can cause plastic conveyor belts in food factories to oxidize and age, with different materials exhibiting varying degrees of tolerance. To address this, a more refined approach can be taken, including controlling the concentration, shortening contact time, selecting oxidation-resistant materials, and employing differentiated disinfection methods and rotating disinfectants, thus balancing disinfection effectiveness with equipment protection.

When using chlorine dioxide for disinfection in food production, the disinfectant concentration is a critical control point in the HACCP system. Test strips are convenient to use but have a relatively large margin of error; portable testing instruments offer higher accuracy but require regular calibration and maintenance. Enterprises can adopt a three-tiered monitoring solution: primarily online sensors, supplemented by portable instrument inspection and calibration, and emergency verification using test strips. This enables continuous monitoring, data retention and traceability, ensuring both disinfection effectiveness and food safety.
