The results associated with fruit firmness as influenced by chitosan coatings showed
that maximum fruit firmness was retained in fruits treated with Crab Chitosan 200 kGy
(T3) followed by the fruits treated with unirradiated Crab Chitosan and minimum fruit
firmness was noticed in untreated control fruits (T1). The data presented revealed that
there was a similar decreasing trend in fruit firmness in all treatments towards the end of
storage. Minimum firmness was calculated after 6 weeks of storage while maximum,
recorded at the time of harvest (Fig. 1b).
