A study was conducted to look at the effect of chitosan coating
at low concentration
on appearances, colour measurement, pH, fruit firmness, total soluble solid and
weight loss of tomatoes. 11 was carried out at Post Harvest Laboratory, Department
of Agrotechnology and Food Science University Malaysia Terengganu. The fruits
coated with chitosan solution at concentrations of 0% as control, 0.25%, 0.5% and
1.0% held at ambient conditions of for 12 days. The experimental design was a
Completely Randomize Design (CRD). The fruits coated with 1.0% chitosan was the
best rather than others. The fruits coated with 1.0% chitosan solution gave its effect
(P<0.05) on weight loss, fruits total soluble solid, pH, appearances and hue angle.
The fruits coated with 1.0% chitosan solution gave no significant effect on fruit
firmness. From the result it can be concluded that chitosan coating is able to extend
the storage life of tomatoes and prevent the fruits from decay.
