Ozone systems for Food&Beverage:low impact solutionsto sanitize and extendshelf life

The natural solution: ozoneIn the Food&Beverage, De Nora with the De Nora NEXT ozone systems ensures deep sanitization of surfaces, purification of air and water, and removal of odours from the environment through every stage of the production process. A know-how gained over 90 years of activity makes De Nora the ideal partner of reference for the study of applications, supply and commissioning of ozone systems.

The De Nora NEXT systems, both innovative and easy to use, are based on natural raw materials: air or oxygen. Sustainable, for the environment and humans, they are the ideal solution for those seeking quality, food safety and longer shelf life of the product, with special consideration given to the containment and reduction of consumption and, as a result, costs.

ADVANTAGES:• innovation and technology • ecological sustainability• natural resources• quality• safety • reduction and containment of consumption and costs

Ozone is formed from oxygen, in its pure form or its presence in the air, through an electrical discharge. Such a simple, natural process: once used, it again becomes oxygen.

Safer fruits and vegetables with ozoneSpoilage and pathogenic microorganisms may be transported by food itself, by process water or by air. If not removed, they can easily proliferate and lead to a reduction in shelf life and the possible transmission of illnesses. Moulds and mycotoxins can develop, as well, in the field or on products stored in unsanitized environments. This is the case, for example, with Patulin which can have toxic effects on humans and, specifically, children. Hence, the importance of providing an effective sanitization of the air and water used for the production process, as with the surfaces and equipment with which the products come into contact.

AIR SANITIZATIONThe use of gaseous ozone in storage cells provides a substantial reduction of the microbial load (specifically moulds) with a consequent containment of the perishability of the products, slowdown of the processes of maturation, decrease in losses and longer shelf life.

SURFACES AND EQUIPMENTThe use of ozonated water on surfaces and work equipment provides a deep sanitization which prevents cross contamination and, at the same time, leaves no residues. In addition, it is proven effective in the battle against biofilm.

PROCESS WATER AND CLEANING WATER The use of ozonated water to wash foods and in the entire storage process, reduces the presence of mycotoxins such as Patulin, can reduce pesticide residues, and permits the microbial load in cleaning water to be contained, making it possible to re-use it, thereby reducing relative consumption and costs.

Ozone: quality and food safety start here

The applications of ozone in the food industry, dairy industry, in the processing and transformation of meat and fish, and production of fresh pasta are extremely varied and can be introduced synergistically across the entire chain: today, consumers demand safe, healthy food which is not overly-processed and is able to satisfy their nutritional and organoleptic desires. Ozone is a natural solution, leaves no olfactive residues and does not alter the flavour of foods. It is able to guarantee high qualitative standards for the food market in developed countries, as well as an opportunity in developing countries which are defining their own standards of food quality.

AIR SANITIZATIONThe use of gaseous ozone in the cheese industry is effective in the maturation rooms against mites and microorganisms of the genus Listeria and reduces the development of unwanted moulds in all environments where processing

and packaging are performed. It is also used in the meat, fish and fresh pasta industries to contain the microbial load. It can also be used for the sanitization of air in work environments such as clean rooms, cooling rooms and storage of products to guarantee a longer shelf life.

SURFACES AND EQUIPMENT During food processing, the use of ozonated water keeps the microbial load at low and consistent levels unlike untreated water, where the levels tend to increase over the course of the day. In addition, the passage through pipes reduces any biofilm present and prevents it reforming and contaminating the product.

PROCESS AND CLEANING WATER The use of ozone to sanitize process water guarantees a reduction of the microbial load and cross contamination by microorganisms. If used in the treatment of cooling water for mozzarella, it can reduce the presence of Pseudomonas aeruginosa or Pseudomonas fluorescens.The treatment of rinse water used in CIP cycles prevents the transfer of any surviving contamination from one tank to another, following the sanitization process.

Beverages: hygiene and savings with ozone In the beverages industry, sanitization is a key issue. On one side, there is the need to guarantee high standards of hygiene, and on the other is the need to reduce impact on the environment and treatment costs. The use of ozone not only allows maximum safety to be achieved, thereby decreasing the microbial load and presence of chemical residues, it also provides substantial savings in water and electricity, optimisation of the production processes, increased operator safety, a noticeable reduction in environmental impact, resulting in lowered costs to the company.

AIR SANITIZATION The use of gaseous ozone reduces the levels of fungi in the air and environments.In the wine industry, in particular, it can lead to a reduction in the number of spores which can be deposited on products and, in addition, proves effective in combating the presence of insects, specifically, Drosophila suzukii.

SURFACES AND EQUIPMENTThe use of ozone in the treatment of steel, resin and cement tanks, as well as barriques and casks, reduces the growth of bacteria, mould, fungi and yeasts, of the genus Brettanomyces bruxellensis reducing the generation of unwanted odours, biogenic amines, acetic acid, ethyl and vinylphenols. Dissolved in water, it becomes an effective means of combating the formation of biofilm in conduits and process lines without the risk of leaving a residue from disinfectants or chemical compounds.

PROCESS WATER AND CLEANING WATERThe use of ozone also proves effective in the treatment of water used to produce beverages for the purpose of preventing unwanted flavours and odours. It also allows the removal of metals, iron and manganese in particular and if used during CIP processes, it prevents contamination with the water used during the rinse stages. Lastly, it can be used in the rinsing machines which are employed in the normal bottling process.

Reduction in water and energy consumption• no water used• the pumps consume less power

Reduction of volumes of water sent to the purifier • 40% less production of sludge

Reduction of mould, yeasts and bacteria• effective against Brettanomyces bruxellensis • does not create resistant strains

CASE HISTORY

Wine industry: sanitization with ozone is convenient. All the advantages compared to chemical products.

The use of ozone systems allows a substantial reduction in levels of COD, BOD and micropollutants, resulting in lower usage of chemical compounds. The use of ozone in a biological purifier can improve its effectiveness and reduce the sludge produced, leading to a positive economic impact on disposal costs. It also prevents the creation of enormous collection tanks. If used prior to biological treatment, ozone can reduce the COD before the waste water is introduced into the tank; the BOD/COD ratio increases as well as the biological efficiency. Used after the biological treatment, ozone can reduce the residual presence of COD and germs. In this way, the discharge limits are managed in accordance with current laws. Ozone, in addition, may be successfully used to reduce the production of organic dewatered sludge. The improved sedimentation and lower index volume of sludge, as well as increased dehydration and the consequential decrease in the use of chemical products, guarantee improved efficiency of the treatment system.

Waste water and sludge: reduce the costs with ozone

Among the principal costs faced by the food industry and livestock breeders, in addition to water and energy, are the costs of waste water treatment; above all if contaminated by biological and chemical products responsible for the increased levels of COD, BOD and micropollutants.
