Abstract.
The Most citrus fruits are compromised each year due
to post-harvest fungal infections. To reduce fungal infections, packing centers use fungicide solution mixtures to prevent
infections that occur during harvest and then during storage. The most common
fungal pathogens of citrus are commonly treated with the fungicides imazalil, Pyrimethanil due to their effectiveness in
controlling these pathogens at low cost and ease of handling. However, little
is known about how it alters tissues in citrus physiology. In this study we
will investigate the behavior and retention of imazalil and pyrimethanil in the tissues of the red
grapefruit fruit (peel and core before washing and after washing with hot water
and simple dish detergent).
This work demonstrates a viable approach for
assessing the quality of citrus fruits, and we can even proceed to thoroughly
wash each fruit before consumption, as we remove a quantity of residue.
This work demonstrates that the treatment
affects the citrus tissues and the substances migrate throughout the pulp,
although the treatment was applied to the peel.
Washing, which is the first step in food
processing on a domestic and industrial scale, helps to reduce pesticide
residues on the fruit surface. In this study, the effectiveness of washing the
peel was also investigated. Although many chemicals are applied to citrus to
prevent certain diseases or control pests, there is little literature available
on how these treatments alter the physiology of the fruit. Usually, the
packaging only analyzes the level of treatments on
the products.
