Abstract
Tomato fruit, considered the second most important vegetable in the world in
terms of quantity of vitamins and minerals contributing to the human diet, is affected
by postharvest diseases that significantly increase spoilage after harvest.
Furthermore, economic losses due to postharvest diseases are even greater than
generally realized because the value of the produce increases several-fold while
passing from the field to the consumer. Because the increased concerns regarding
food safety of fresh vegetables we developed a PAA formulation and application
system for the hygienic washing of tomatoes. It turns out that this application is also
extremely effective reducing postharvest decay. In the present study, the postharvest
application of Citrocide® PLUS on tomatoes was evaluated. Citrocide® PLUS, a PAA
based formulation from Productos Citrosol S.A., was applied to three different
tomatoes cultivars. In two cultivars, fruit was wounded simulating cracking, while in a
third one, tomatoes were harvested from a greenhouse with, presumably, high level
of fungi inoculum. The results obtained showed that the proper application of
Citrocide® PLUS significantly reduces tomatoes postharvest decay in all cultivars
tested. Decay reduction index vary from 85% to even 100% after 10 days at 10ºC and
85% RH in wounded tomatoes, while in non-wounded tomatoes decay control was
100% after 13 days at 10ºC and 85% RH. In addition, the results showed that the
avoidance of washing tomato cannot be considered as an alternative to reduce
postharvest decay. This study indicates that the postharvest application of Citrocide®
PLUS is a reliable solution to improve postharvest life of tomatoes and therefore,
reduce tomato economic losses caused by decay after harvest.
