Tomato Ozone Sanitization Initiative

Tomatoes are a popular vegetable enjoyed by many people, both raw and cooked. Known for their delicious taste, tomatoes are cultivated in various regions and are generally easy to grow. The production of tomatoes in many countries is substantial, leading to significant challenges in storage.

Research over the years has highlighted the effectiveness of ozone in extending the shelf life of tomatoes. For instance, when storing late-maturing varieties, these tomatoes are often harvested before they reach full maturity. To enhance their storage life, the cold storage facility is treated with ozone to ensure complete disinfection prior to storing the tomatoes. When maintained at optimal temperature and humidity levels, tomatoes can be preserved for up to two months. The use of ozone for sterilization significantly prolongs their freshness, and the process is efficient, requiring no daily disinfection, which in turn reduces both labor and costs.

It is important to handle the tomatoes with care during storage to avoid bruising or breaking them. After the initial disinfection, the ozone generator should not be placed inside the cold storage due to the high humidity levels. Instead, it is advisable to keep the ozone generator in a dry, well-ventilated area to prolong its lifespan.

In summary, using ozone for the disinfection and storage of tomatoes presents a practical solution to one of the major challenges faced by producers, allowing for longer preservation and reduced operational costs.
