Chitosan-based fruit coating as postharvest treatments on two pineapples (Ananas comosus L. Merr) clones

Abstract Production of fresh pineapple fruit is dominated by the MD2 clone, while GP3 clone used as canned fruit. To be promoted fruit, has some defects, namely a less sweet taste and sensitivity to internal browning (IB) disorders. The clones need coatings, two might get responded differently. This study aimed effects chitosan-based coating mixed with palm stearin Aloe vera gel on qualities clones, well seek potential 2 x 4 factorials. first factor was (GP3 MD2). second coatings (control, chitosan, + chitosan). fruits were stored at 7 °C. results showed that started show incidence IB disorders 21st day, weeks earlier than MD2. °Brix 16.82% vitamin C 391.45 mg/L, which significantly higher GP3. Meanwhile, 0.60% acidity, These indicated should not for consumption, mainly because its lower sweetness compared clone. chitosan treatment, added or stearin, value other treatments.
