One of the most important problems in storing
apples is skin browning (scald). Apples brown after 2–
4 months of storage. Thus, it is not possible to predict
the intensity of scald and its dependence on the date of
harvest. To prevent scald development, fruits are
treated with chemicals. Previously, diphenylamine was
used for this purpose. Apples were dipped in a solution
of this element. Later, 1methylcyclopropene gas was
applied in order to inhibit ethylene synthesis in fruit
[1]. As a result, apples were kept from ripening, which
also reduced the risk of scald.
