APPLICATION OF OZONE GAS IN COLD ROOMS

ISSUE

Ozone in Cold room for fungus, mould, bacteria & ethylene control. It also neutralises Linuron carried over from herbicides.

Using Ozone in Cold Storage dramatically reduces the potential for spreading germs from handling foods such as meats, fish, fruits and vegetables.

Microorganisms such as bacteria, moulds and yeast that can grow in refrigerators, cause spoilage and decrease shelf-life.

Organic or bacterial “slime” grows on produce and refrigerator coils, pans, and in drain lines that can block or restrict flow, causing cross-contamination to the other foods in the refrigerator.

Ethylene is produced from all parts of higher plants including the leaves, stems, roots, flowers, fruits, tubers, and seeds.

During the life of the plant ethylene production is induced during certain stages of growth such as germination, ripening of fruits, abscission of leaves, and senescence of flowers.

Plant reactions to ethylene include stimulation of the aging process in leaves & flowers, the shedding of leaves & flowers, ripening of fruit and a climacteric rise in respiration in some fruit which causes a release of additional ethylene.

EFFECTS OF ETHYLENE ON PLANTS

  • Ethylene shortens the shelf life of many fruits by hastening fruit ripening and floral senescence.
  • Ethylene will shorten the shelf life of cut flowers and potted plants by accelerating floral senescence and floral abscission.
  • Flowers and plants which are subjected to stress during shipping, handling, or storage produce ethylene causing a significant reduction in floral display.
  • Flowers affected by ethylene include carnation, geranium, petunia, rose, and many others.

SOLUTION

Oz

Ozone in Cold room for fungus, mould, bacteria, ethylene and Linuron control.

Using Ozone in Cold Storage will increase shelf life by controlling ripening and reducing decay.

Common items that benefit from Ozone in Cold Storage are Apples, Avocados, Bananas, Berries, Citrus, Cucumbers, Grapes, Onions, Pears, Peppers, Potatoes, Stone Fruit and Tomatoes.

Ever increasing concerns regarding extending shelf-life, control of decay, control of ripening, quality and appearance of food without depending on chemicals have driven increased demand for safe, proven food storage alternatives such as ozone.

Studies show that with the Ozone gas kept at above 0.4ppm in the cold room, the shelf life of stored fruits and vegetables increases significantly.
