Results showed that the
use of pre-treatments reduced the vitamin C degradation with sodium metabisulphite registering the
highest reduction and the control samples the lowest reduction. Furthermore, pre-treatments
significantly affected (p<0.05) affected sensory quality attributes in different ways. However, texture
was not affected by the use of pre-treatments. Pre-treated fruit samples had better colour than the
control samples. It was further found out that control samples had higher scores in taste and flavour
with the exception of pineapples, where the pre-treated samples had a higher score than the control
samples.
