3.3. Effects of chitosan coating on total soluble solids, titratable acidity, and ascorbic acid
The titratable acidity and contents of total soluble solids and ascorbic acid decreased (Table 1), which was consistent with decline in eating quality. The fruit treated with 2% chitosan had a higher ascorbic acid content than either of the other treatments or the control, which can be attributed to low respiration (Fig. 1).
