Product development of osmotically dehydrated banana peels. (musa sapientum)

Abstract

This research aimed to investigate the suitable method to product osmotically dehydrated banana peels and determine its shelf life as well as consumer acceptation. It was found that the proper method was the slow osmotic dehydration process with 30, 40 and 50% of syrup (sucrose solution). This method led to the highest appearance, color and flavor scores as accessed by the consumer. Therefore, the slow osmotic dehydration process was selected for further study relating to the ratio between salt and malic acid (3:2, 3:3 and 2:3 of syrup weight). The result show that no differences in appearance, color, flavor and texture scores were found among treatments, however the sample treated with salt and malic acid in the ratio of 3:3 obtained the highest taste score. Thus, the suitable process to produce the osmotically dehydrated banana peels was slow process with salt and malic in the ratio 3:3. According to the shelf life study, the sample (100g) packed in metallic foil still compiled with Thai community standard of fruit and vegetable products during 12 weeks of storage under 25-30 °C. In addition, the consumers also accepted the selected osmotically banana peel product.
