The World Health Organization's data on 600 million foodborne illnesses reflects the severity of the impact on food hygiene and safety. The root of the data lies in how to effectively prevent and control food processing hygiene? Is it the law? Is it a policy? These are not absolute conditions, they are disinfection processes. Only by starting with disinfection technology can we effectively ensure the health and safety of the global population.

In today's increasingly strict global food safety regulations, chlorine dioxide has entered the field of food processing. With its high load of organic matter, flexible adaptability, and no disproportionation reaction, it enables complex ingredients, precision equipment, or abnormal environments in food processing to destroy a large number of microbial armies on its own, achieving the key bottleneck problem of disinfection in the food industry - physical sterilization.

Unlike traditional disinfectants that only pursue sterilization rate, the entire disinfection process of chlorine dioxide is a systematic reconstruction. Firstly, we need to innovate the disinfection mechanism at the molecular level. Secondly, we need to improve the disinfection process control mode. Thirdly, we need to enhance the traceability efficiency of residual detection. These three aspects are interrelated, making disinfection more capable of maintaining certainty and bringing many energy-saving and efficiency enhancing improvements to food processing disinfection supervision.

1、 Mechanism of action and technological advantages

Chlorine dioxide uses the "heart attack" method to disable the infectivity of viruses, directly dismantling or destroying the central gene nucleic acid structure of the virus, making it no longer replicable and mobile. In terms of bacterial response, the goal is to first degrade the protective cell membrane tissue, by molecularly disintegrating the surface amino acids of bacteria, causing them to lose their barrier and rapidly decay.

The above disinfection mechanism is the unique "targeted control" disinfection technology of chlorine dioxide. Accurate positioning, targeted attacks, no damage to any friendly forces, and a literacy style clearance of enemy forces mixed in food. This unique mechanism not only avoids the hidden problem of microbial resistance, but also increases the probability of microbial killing efficiency and reaction rate compared to traditional disinfectants.

2、 Classification application standard based on concentration gradient

Food professionals in the industry are well aware that the same type of substance has completely different properties and risks under different levels of contamination. The use of chlorine dioxide, even if there are significant differences in concentration, can still achieve precise image matching based on different levels and concentrations. According to industry standards related to chlorine dioxide (including GB/T26366-2020 "Hygienic Requirements for Chlorine Dioxide Disinfectants"), the concentration gradient control in food processing environments can be scientifically controlled by referring to the following parameter ratios:

1. Water treatment disinfection: Controlling chlorine dioxide at a ratio of 0.2-1.0mg/L can not only remove impurities and odors in water, but also have significant treatment effects on raw water with high iron and manganese content.

2. Disinfection of food contact surfaces: Food workshops are mostly made of materials such as stainless steel and plastic, and use a 50-200mg/L mixed solution. Assisted disinfection methods such as atomization, scrubbing, or irrigation can ensure that all contact surfaces and dead corners are thoroughly disinfected to meet strict hygiene standards.

3. Preservation and preservation of fruits and vegetables: For the cleaning process of refrigerated fruits and vegetables, a concentration ratio of 50mg/L should be used for processing mode, and a concentration ratio of 10mg/L should be used for preservation mode to achieve various flavor requirements such as delayed ripening and stable freshness.

4. Space environment disinfection: Large scale disinfection is often carried out by atomization operation, with a dosage of 100 milligrams of solution, 10 milliliters per cubic meter, and sealed for 30 minutes, which can globally kill natural bacteria in the air.

3、 Progress in detection technology for residual control

After the disinfection focus is resolved, we enter the disinfection backend stage. The index compliance issue in this link is particularly worrying. If the detection method is not appropriate, it will still cause problems such as complicated processes and low efficiency. To this end, China's development of testing technology has risen to the challenge, continuously improving and innovating to construct various testing processes suitable for diverse scenarios, and building a solid hygiene defense line for food safety.

1. Improved five step iodometric method: It is a technology that can firmly lock in multiple laboratory indicators of chlorine dioxide, chlorite, and chlorate with ultra-low detection limits as low as 0.02mg/L under different pH water quality conditions. Its extremely small tolerance of ≤ 2.1% confirms its high stability and safety in detection.

2. Ion chromatography: This method uses efficient separation techniques for chromatographic measurement, accurately detecting the volume of trace by-products. Becoming an authoritative testing method for complex food materials such as fresh meat and aquatic products.

3. Electrochemical sensing technology: This method uses highly sensitive materials such as nano gold and carbon nanotubes as sensing components to perform charge sensing reactions. It has the advantages of fast response and convenient operation, and is often used for on-site real-time quality inspection applications.

From core technology to terminal detection, every detail and process is striving for scientific rigor, stability, and reliability. The above various detection technologies are only aimed at firmly controlling safety within the threshold range, making the

production quality of enterprises more trustworthy.

4、 Accurate disinfection technology empowers brands

Xiuba, a brand that specializes in chlorine dioxide as a single category marketing, focuses not on products, but on the development of chlorine dioxide technology and efficiency improvement, which is a core strength that many disinfectant manufacturers aspire to. Although Xiuba has gone through more than 30 years of ups and downs, it has not changed its original intention in the industry, constantly expanding its product line from liquids to effervescent tablets, to powders, and now developing more product types with different blending ratios to meet the complex food production needs in China.

1. Scene adaptation of multi dosage form matrix

The Xiuba food processing series disinfectant has rich application and selection conditions in various scenarios. Among them, 4% chlorine dioxide disinfectant powder adopts one yuan packaging technology, which can be used for disinfection of general object surfaces, air, food processing pipelines and other scenarios. 10% chlorine dioxide disinfectant powder has been improved by the new national standard, with a significantly increased conversion rate, and can kill bacteria such as Escherichia coli, Staphylococcus aureus, and Staphylococcus aureus. There is also a 23% chlorine dioxide disinfectant powder type II (A and B agent set products), which comes with a high content, meaning that sterilization is fast and thorough, and can maintain the hygiene and stability of the product shelf life for a long time.

In addition, Xiuba Food Processing Series disinfectants have multiple other options with unique advantages, which are applied in different production environments and have obtained national food safety certification. Matching the needs of processing and disinfection, targeted selection is the preferred solution for customized disinfection in food processing.
