Abstract: The use of electrolyzed oxidizing water for cleaning and disinfecting production pipelines, storage tanks, and beer bottles in beer production enterprises is significantly more effective than traditional CIP and caustic soda bottle cleaning processes. At the same time, it can also reduce the cost of cleaning and disinfection, shorten the cleaning and disinfection time, improve production efficiency, and reduce carbon dioxide emissions. This new disinfectant and cleaning disinfection process can be fully matched with the existing production equipment of the enterprise without changing its conditions, which is a new idea for beer production enterprises to explore "cost reduction, energy conservation and emission reduction".

The cleaning and disinfection of production pipelines, storage tanks, and beer bottles by beer production enterprises are key processes in the beer production process. The effectiveness of cleaning and disinfection will directly affect the internal and external quality of beer. Currently, beer production companies are using the CIP method. Use hot water and strong acidic and strong alkaline chemical solutions to cycle clean and disinfect pipelines and containers. In the CIP process, acidic chemicals mainly use nitric acid solution, which is a toxic substance. Due to the operator's carelessness, accidents often occur when nitric acid solution is mixed into pipeline food materials. Once it enters the market, it will have serious consequences for consumers and even lead to an uncontrollable situation for the enterprise. In addition, the storage and use of toxic chemicals in food enterprises objectively pose hidden dangers to food safety and employee personal safety issues. For the cleaning and disinfection of beer bottles, most manufacturers still use strong alkali and high temperature methods, which have poor cleaning and disinfection effects. The surface of the cleaned object is prone to water streaks and residual sodium hydroxide, which not only affects the appearance but also changes the taste of the beer; At the same time, the discharge of strongly alkaline wastewater increases the cost of enterprise wastewater treatment and has drawbacks such as increased energy consumption. Can we find a non-toxic and harmless cleaning agent that can ensure thorough cleaning and disinfection to replace the current methods of using strong acid, strong alkaline solutions, and high temperature energy consumption? The answer is affirmative! Electrolyzed oxidizing water (EOW) is one of the best alternatives. 1、 Introduction to oxidation potential water: 1. The generation principle of oxidation potential water is to add less than 0.05% NaCl to tap water, and electrolyze it through a specially designed ion exchange membrane electrolytic cell to generate acidic oxidation potential water at the anode; Generate alkaline oxidation potential water at the cathode. 2. Physical and chemical properties of electrolyzed oxidizing water Acidic electrolyzed oxidizing water is a broad-spectrum, efficient, non-toxic, harmless, non irritating odor free, colorless, transparent, and environmentally friendly disinfectant. The physical and chemical indicators specified by the Chinese Ministry of Health standards are: ① pH value: 2.0-3.10; ② Effective chlorine content (ACC): 50-70ppm; ③ Redox potential (ORP):>+1100mV; ④ Residual chloride ions:<1000mg/L; ⑤ Exposure to air, light, or heating above 40 degrees Celsius can gradually restore it to normal water. Alkaline oxidation potential water is a highly efficient cleaning agent that is colorless, transparent, and free of irritating odors. Its physical and chemical indicators are: ① pH value: 11-12; ② Redox potential (ORP): -870 to -840mV. 3. The physical theory of the sterilization mechanism of acidic oxidation potential water mainly includes the oxidation-reduction potential theory, electron motion theory, and electric conductivity theory. The low pH value (2.0-3.0) and high oxidation-reduction potential (ORP ≥+1100mV) of acidic oxidation potential water exceed the survival range of microorganisms and cause changes in the membrane potential of microbial cells, leading to increased cell membrane permeability, destruction of cellular metabolic enzymes, and precipitation of intracellular substances, achieving the effect of killing microorganisms. Chemical theory: In addition to low pH and high ORP, the main components of its antibacterial properties include hypochlorous acid, hydrogen peroxide, and OH groups. It is interesting that these components have exactly the same composition as the reactive oxygen species responsible for the bactericidal effect on neutrophils. After extensive scientific experiments, this theory was confirmed in 1998, establishing that effective chlorine in acidic oxidation potential water is one of the main factors in killing pathogenic microorganisms. 4. The bactericidal characteristics of acidic oxidation potential water include broad-spectrum sterilization and rapid sterilization. Multiple studies at home and abroad have shown that acidic electrolyzed oxidizing water can not only kill bacterial colonies and viruses, but also kill various pathogenic microorganisms such as spores, as shown in Table 1. The efficacy of killing microorganisms published by the National Center for Disease Control and Prevention is shown in Table 1

5. The safety of acidic electrolyzed oxidizing water has been proven by the National Center for Disease Control and Prevention, as well as domestic and foreign scientists, through acute oral toxicity tests, skin irritation tests, eye irritation tests, animal bone marrow cell micronucleus tests, and cytotoxicity tests, that acidic electrolyzed oxidizing water is a safe, reliable, and non-toxic disinfectant. 6. The environmental friendliness of acidic oxidation potential water is due to its ability to automatically reduce to ordinary water when exposed to light, air, and temperatures above 40 ℃. Therefore, its environmentally friendly characteristics of no residue and no pollution can achieve zero emissions. 7. Cleaning mechanism of alkaline oxidation potential water: Alkaline oxidation potential water has a high pH value (above 11) and a negative oxidation-reduction potential (ORP ≤ -800), with small molecular clusters and good permeability; It has strong reducing ability, and its cleaning ability at room temperature is better than that of hot alkali at 80 ℃, with extremely strong cleaning ability. In summary, acidic electrolyzed oxidizing water is an environmentally friendly disinfectant with extremely strong bactericidal ability; Alkaline oxidation potential water is a cleaning agent with extremely strong cleaning ability. The National Health Department issued the "Disinfection Technical Specification" (2002 edition) in 2003, the industry standard (WS310.2-2009) of the Ministry of Health in 2009, and the "List of Raw Materials (Ingredients) for Food Disinfectants" (2009 edition) in 2010, laying a solid foundation for the disinfection application of electrolyzed oxidizing water in the food industry. The scope of use of electrolyzed oxidizing water products approved by the Ministry of Health is: ① hand disinfection for hygiene; ② Disinfection of skin and mucous membranes; ③ Disinfection of tableware; ④ Disinfection of fruits and vegetables; ⑤ Disinfection of food processing pipelines and equipment; ⑥ Disinfection of the environment and surfaces of objects; ⑦ Disinfection of medical equipment, etc. 2、 Application of Oxidized Potential Water in CIP Process of Beer Production Industry 1. Advantages of Oxidized Potential Water in CIP Process Currently, in the CIP technology of production pipelines and storage tanks in the beer production industry, a new type of efficient, non-toxic, and environmentally friendly cleaning and disinfection solution - Oxidized Potential Water is at the forefront of the world. The US FDA has approved the legal use of electrolyzed oxidizing water in the food and medical industries. The Coca Cola Company in the United States has designated the use of electrolyzed oxidizing water as a cleaning and disinfecting solution for CIP process in its global filling factories, and has installed and used it in three filling factories in China, achieving good results. The China Beer Association has also included the application of electrolyzed oxidizing water as a technological innovation project in the 12th Five Year Plan. The application of electrolyzed oxidizing water in CIP process has introduced a new concept of "cold disinfection", which is characterized by the ability to clean and disinfect at room temperature without using thermal energy to achieve complete disinfection. Its main characteristics are as follows: ① Broad spectrum and high efficiency, capable of killing common pathogenic bacteria within 30 seconds; ② No toxic side effects, no harm from accidental ingestion; ③ No irritating effect on human skin; ④ Completely environmentally friendly, achieving zero emissions, and meeting the requirements of clean production; ⑤ Without using a heat source, it can save a lot of heat energy and reduce carbon emissions; ⑥ The operating cost is low, with a cost of only 0.018 yuan per liter of oxidation potential water; ⑦ Greatly shortened the CIP process time, only one-third of the original time; ⑧ Can increase factory production efficiency by about 10%; ⑨ No equipment modification required, convenient to use.
