ABSTRACT

Tomato is one of the vegetables that stands out for being consumed in the whole world, besides being a source of nutrients, such as vitamins C and E, phenolic compounds and carotenoids. It is widely used as a raw material for processed products, such as sauces, juices, among others, but also in fresh, um salads and minimally processed form, because its association with cancer prevention. The fruit's respiration is affected by the high temperature of the tropical regions, impacting its ripening and deterioration, so it must be submitted to processes that preserve its quality, such as pre-cooling to reduce its heat and a treatment that inhibits microbial growth. The tomato is subjected to a high microbial load during its development, which can be natural of the product or due to the agricultural practices, which implies both the presence of pathogenic and phytopathogenic microorganisms. Hypochlorite is the most widely used product in plant sanitation, but is associated with the formation of carcinogenic products and ineffective action. As an alternative, ozonation is able to act on a large range of microorganisms and leave no residue, besides being recognized by the FDA as a safe treatment. Another product that has been widely used by the food industry is chlorine dioxide, which is strongly oxidizing and does not react with organic matter. This work aims to evaluate the action of sanitizers cited in the treatment of tomato, to replace the use of chlorine. They are expected to have effective action on inoculated phytopathogens, avoiding post-harvest diseases in tomatoes.
