Abstract
Production of fresh pineapple fruit is dominated by the MD2 clone, while the GP3 clone is used as canned fruit. To be promoted as fresh fruit, the GP3 has some defects, namely less sweet taste and sensitive to internal browning (IB) disorders. The clones need fruit coatings, and the two might response differently. This study aimed to study the effects of chitosan-based fruit coating mixed with palm stearin and Aloe vera gel on the fruit qualities of the two clones, as well as to seek the potential of GP3 clone as a fresh fruit. The study used 2 x 4 factorials. The first factor was two clones (GP3 and MD2). The second factor was fruit coatings (control, chitosan, palm stearin + chitosan, and Aloe vera gel + chitosan). The fruits were stored at 7 ºC. The results showed that the GP3 began the incidence of IB disorders on the 21st day, much more earlier than the MD2 which was on the 35th day. The MD2 showed a ºBrix of 16.82% and vitamin C of 391.45 mg/L which were significantly higher than the GP3. Meanwhile, the GP3 showed 0.60% acidity which was significantly higher than the MD2. Fruit coatings mixed with the natural ingredients were able to maintain ºBrix and acidity values, especially in the MD2. These indicated that the GP3 should not be considered as an option for fresh fruit consumption, especially because of its sensitivity to IB and lower sweetness compared to the MD2 clone.
