Food factory disinfection ceiling - chlorine dioxide safe and efficient fumigation solution

In 2026, the "Detailed Rules for the Examination of Production Licenses for Egg Products (2025 Edition)" officially came into effect. This new regulation sets higher requirements for microbial control in the production of aseptic eggs (eggs suitable for raw consumption). It not only significantly raises the detection standards for pathogens such as Salmonella and Listeria, but also formally incorporates the disinfection standards for the entire production process into the core assessment indicators for license examination. Faced with these stringent new requirements , many aseptic egg processing companies are optimizing their disinfection solutions, striving to find a disinfection product that can effectively kill bacteria, leave no residue after disinfection, and is compatible with all stages of processing. Among numerous disinfection solutions , chlorine dioxide, with its unique physicochemical properties, has become the preferred disinfection raw material for all stages of aseptic egg processing . Especially the powder form, due to its flexible formulation, simple operation, and convenient storage, is widely recognized by food processing companies.

Disinfection challenges in aseptic egg processing are prominent; how can chlorine dioxide precisely address them?

The core selling point of sterile eggs is that they are "safe to eat raw," which requires strict control of pathogens throughout the entire supply chain, from egg farming to final storage. However, in actual production, traditional disinfection methods have always had unresolved problems in the sterile egg processing stage: sodium hypochlorite disinfection can easily produce chlorinated organic residues, which can also react with the nutrients in the eggs, directly affecting the quality of the eggs themselves; alcohol can only provide rapid surface disinfection and cannot completely eliminate pathogens in equipment crevices and hidden corners of the chicken coop; the effectiveness of ozone disinfection is greatly affected by environmental temperature and humidity, and its sterilization effect is very unstable, making it impossible to guarantee consistent disinfection.

Chlorine dioxide, as a fourth-generation disinfectant, is perfectly suited to the disinfection needs of the entire aseptic egg processing process. It has a particularly broad bactericidal spectrum, achieving a 99.99% kill rate against key pathogens in aseptic egg control, such as Salmonella and Listeria . Its bactericidal mechanism is also unique, achieving sterilization by disrupting the cell membrane and nucleic acid structure of microorganisms, without producing carcinogenic, teratogenic , or mutagenic substances, and leaving no residue after disinfection. It also has strong adaptability, maintaining stable bactericidal effects in both acidic and neutral environments, demonstrating excellent results in both aquatic disinfection during aquaculture and hard surface disinfection in processing workshops. It is precisely because of these advantages that chlorine dioxide disinfectant powder has become the core choice for disinfection throughout the entire aseptic egg processing process.

Xiuba chlorine dioxide disinfectant powder, relying on industry-leading production technology, increases the activation rate of chlorine dioxide to over 95%, with precise control over the content of effective ingredients, fully meeting the stringent standards for food-grade disinfection. Its core R&D team members were deeply involved in the formulation of the national standard "Stable Chlorine Dioxide Solution (GBT20783-2023)," possessing in-depth and professional industry understanding of the actual application processes of chlorine dioxide. Furthermore , they have specifically optimized the dissolution rate and mixing ratio of the disinfectant powder for each specific stage of aseptic egg processing , allowing disinfection operations to better align with the actual production rhythm of enterprises, making it more convenient and efficient to use.

Application Process of Chlorine Dioxide Disinfectant Powder in the Whole Process of Aseptic Egg Processing

Disinfection control for sterile eggs is not a "single point" but rather involves the entire chain from breeding, collection and cleaning, production and processing, to storage and transportation. The disinfection requirements are different at each stage, and the ratio and operation method of chlorine dioxide disinfectant powder also need to be adjusted accordingly. The following are mature application processes that have been verified by a large number of practical applications:

Farming process: Source disinfection and control of microbial risks from the laying hen end.

Quality control of sterile eggs begins in the laying hen breeding stage. Drinking water and the henhouse environment are the main channels for the spread of pathogens. Xiuba chlorine dioxide disinfectant powder, diluted at a ratio of 1:5000, can be directly used for daily disinfection of the laying hens' drinking water, continuously inhibiting the reproduction of microorganisms in the water and reducing the probability of intestinal pathogen infection in laying hens, thus reducing the possibility of bacteria-carrying eggs from the source. For henhouse floors, cages, ventilation equipment, etc., disinfectant powder is diluted at a ratio of 1:2000 and disinfected daily by spraying or wiping. Increasing the frequency of disinfection before slaughter can effectively eliminate pathogens in the henhouse environment, laying a "sterile foundation" for egg products.

This formula has been optimized through long-term practice. The disinfectant powder dissolves quickly without sedimentation, will not clog the drinking water system of laying hens, and has no irritating odor, so it will not affect the normal growth of laying hens.

Egg Collection and Cleaning: Light disinfection to protect the natural protective barrier of the eggshell.

The new regulations explicitly require that aseptic egg processing avoid squeezing and breaking the shell. The natural gelatinous layer on the eggshell surface is a "natural protective shield" for eggs. Disinfection must kill pathogens on the surface without damaging this gelatinous layer. Xiuba chlorine dioxide disinfectant powder, diluted at a ratio of 1:3000, can be used to disinfect freshly collected eggs by spraying or short-term soaking. Soaking time should be controlled at 3-5 minutes, and the spray pressure should be maintained at 0.2 MPa. This method can quickly remove pathogens such as Salmonella from the eggshell surface without damaging the gelatinous layer, preventing water stains from carrying bacteria into the egg.

Disinfected eggs can be directly processed into the drying process without secondary cleaning, as Xiuba chlorine dioxide disinfectant powder leaves no residue after disinfection, which improves processing efficiency and fundamentally avoids secondary contamination.

Production workshop: Thorough disinfection to create a sterile processing environment

The sterile egg processing workshop is the core area for the prevention and control of pathogens. Equipment, floors, walls, operators and tools are all key points of microbial contamination and must be disinfected in accordance with the new regulations to achieve routine and comprehensive disinfection .

1. Equipment and Pipeline Disinfection: Equipment such as egg beaters, conveying pipes, and storage containers are prone to accumulating dirt and grime in their crevices. Dilute Xiuba chlorine dioxide disinfectant powder at a ratio of 1:1000 and disinfect it by circulating rinsing or soaking. After soaking for 15-20 minutes, let it drain naturally before use. This method can thoroughly kill pathogens in the crevices without causing corrosion to the metal equipment.
2. Workshop environment and air disinfection: After dilution at a ratio of 1:1500, use a misting sprayer to disinfect the workshop floor, walls and air in all directions. Do this once before starting work and once after finishing work each day. The misting particles are controlled at 5-10μm, which can achieve simultaneous sterilization of air and hard surfaces, so that the microbial content in the workshop always meets the aseptic processing standards.
3. Personnel and tool disinfection: Dilute to a ratio of 1:4000 to prepare a disinfectant solution. Disinfect the operator's hands by soaking them for 1-2 minutes. It can also be used to wipe and disinfect operating gloves, knives, trays and other tools, so as to control the risk of human contamination in real time during the processing .

Storage and transportation: Continuous antibacterial action to extend the shelf life of sterile eggs

The shelf life of sterile eggs is closely related to the microbial content of the storage and transportation environment. Disinfection in this stage is easily overlooked, but it is also a crucial point for the prevention and control of pathogens. Xiuba chlorine dioxide disinfectant powder, diluted at a ratio of 1:2500, can be sprayed on the floors and shelves of the storage warehouse every 3 days to effectively inhibit the growth of microorganisms in the environment. Before each loading, transport vehicles should be thoroughly sprayed with the same concentration of disinfectant, allowed to dry, and then loaded with eggs, achieving a sterile closed loop from processing to transportation.

IV. Key Precautions for the Use of Chlorine Dioxide Disinfectant Powder in Aseptic Egg Processing

food- grade disinfection operations for aseptic egg processing , the effectiveness of chlorine dioxide disinfectant powder depends not only on the quality of the product itself but also on standardized operating procedures. In accordance with the hygiene requirements of aseptic egg production, several key points must be strictly controlled in practical use:

1. Prepare and use immediately to control the efficacy of the disinfectant. When preparing the disinfectant powder, only use room temperature water to dissolve it. Do not use hot water, as water temperature exceeding 50℃ will directly reduce the activity of the active ingredients and significantly weaken the disinfection effect. It is recommended to use the prepared disinfectant solution within 24 hours. If left for too long, the efficacy will be lost, and it will not be able to meet the sterilization standards required for aseptic egg processing .
2. Proper storage is essential to ensure product quality. Disinfectant powder should be stored separately in a cool, dry, and well-ventilated area, away from fire and heat sources. It should also be kept strictly separate from food, feed, and other materials, and protected from direct sunlight to prevent the disinfectant powder from becoming damp, clumping, or losing its active ingredients, which would affect its subsequent effectiveness.
3. To ensure proper operational safety, operators must wear rubber gloves and masks when preparing disinfectant solutions to prevent direct contact between disinfectant powder and skin or respiratory tract. If accidental contact occurs, immediately rinse the affected area with plenty of water; no special treatment is required.
4. Precise control of the concentration ratio is crucial. There are clear standards for the dilution concentration of disinfectant powder in different stages such as aseptic egg breeding, cleaning, workshop processing, warehousing and transportation. During operation, the concentration cannot be increased arbitrarily, resulting in waste of raw materials, nor can it be decreased without authorization. The concentration must be kept accurate in order to completely kill all kinds of pathogens and maintain the bottom line of microbial control in aseptic egg processing .

The official implementation of the "Detailed Rules for the Examination of Production Licenses for Egg Products (2025 Edition)" in 2026 marks a new stage of high-quality and standardized development for China's egg product industry.
