The apple (Malus domestica Borkh.) fruit is the second most fre-
quently consumed, after bananas and this is attributed not only to
its organoleptic characteristics but also to its long storability and
availability to the markets for many months. Some quality char-
acteristics of apples directed for fresh consumption are size, color,
aroma, freedom from blemishes, total soluble solid and total acid
content. The apple quality is also determined by their phenolic
content, as they provide taste characteristics such as flavour, bitter-
ness and astringency and induce oxidative browning (Bengoechea
et al., 1997; Fuleki et al., 1994).
