The Application of Ozone Water in Food Processing
The application of ozonated water in food processing is primarily focused on disinfection and sterilization. It can effectively disinfect various stages of the food processing procedure, thereby ensuring food safety. The following is a detailed case analysis.
1. Air disinfection in food processing workshops
In the food processing industry, air disinfection in production workshops is an important step. Ozone water can rapidly eliminate bacteria and viruses from the air, thereby reducing microbial contamination and improving product quality. After enterprises implement ozone disinfection, the bacterial counts on surfaces—including those in production workshops, floors, operating tables, and tableware—have met the required standards. Meanwhile, unpleasant odors in some meat and poultry slaughterhouses have also been significantly reduced.
2. Changing room and workwear disinfection
In food processing enterprises, workers’ uniforms are one of the primary pathways for bacterial transmission. Ozone water can effectively penetrate all parts of clothing, killing bacteria adhering to the fabric and thus preventing bacteria from entering the production workshop.
3. Sterilization and purification of production water
In food processing, the quality of water used in production directly affects the hygienic safety of food. Ozone-treated water can efficiently eliminate bacteria, viruses, and microorganisms from water while also removing organic substances and other contaminants, thereby preventing secondary contamination. For example, a food-processing company in Shandong, after using ozone for water treatment, observed reductions in iron content, total bacterial count, and flocculent sediment in the water.
4. Prepare high-concentration ozone water as a novel disinfectant.
High-concentration ozone water can be used as a new type of disinfectant to sanitize equipment and utensils in food processing. This disinfection method is not only highly effective but also leaves no residues, meeting the requirements for food safety.
5. Disinfection of Food Cold Storage and Fresh-Keeping Cold Storage
In food cold storage facilities, biological contamination is a serious issue. Ozone water can effectively eliminate molds and other microorganisms without inducing resistance, making it a commonly used method for disinfecting cold storage facilities today. For example, some food companies use ozone to disinfect their food cold storage areas, thereby effectively controlling biological contamination.
The above are some specific application cases of ozonated water in food processing. These cases demonstrate the important role ozonated water plays in ensuring food safety.
