Abstract
The challenge of maintaining shelf life will be faced when entering the market share of fresh pineapple. One way that can be used so that the fruit can survive during storage is by coating the fruit. Currently the use of coating materials is still very dependent on imported products. The objective of this study was to study the responses of two pineapple clones of GP3 and MD2 applied with 5 coating materials as post-harvest treatments, consisting of StaFresh 2952, OE6012, palm stearin, chitosan and the control without coating. All treatments were stored at 7oC and observed at days of 0, 7, 14, 21, 28 and 35. The results showed that the GP3 clone was more susceptible to Internal Browning (IB) disorders and this IB began to appear on day 14, much more earlier than the MD2 clone. The GP3 clone showed a Brix value of 13.9% and a vitamin C of 52 ppm which were significantly lower compared to the MD2 clone with a Brix value of 16.4% and a vitamin C of 586 ppm. From the results, the GP3 clone was considered not suitable as a fresh pineapple. The coatings were not able to prevent the IB disorders and to affect respiration rate, but they had significant effects on fruit weight loss, with StaFresh 2952 treatment consistently reduced weight loss by 11.8% until 35 days of shelf-life.
