A comparison of the decay of both TBZ-treated control and chitosan-treated fruit (Fig. 1) indicated that decay in citrus fruit coated with chitosan alone and dipped in TBZ alone was significantly reduced (p < 0.05). However, 0.1% LMWC inhibited control decay in citrus fruit by more than 20%, as compared to that associated with TBZ. The TBZ-treated control did not differ significantly from the fruit treated with 0.1% HMWC, according to Duncan’s multiple range test.
