Abstract:

This study aimed to compare effects of different drying processes such as hot air drying, extrusion drying, vacuum freeze drying and spray drying on retention rate, particle shape, crystal structure, iodine absorption curve, color, water absorption, water solubility of banana resistance starch. For retention and quality of banana resistance starch, vacuum freeze drying, low temperature hot air drying (50 ℃) and spray drying processes are superior to high temperature hot air drying (100 ℃). Moreover, extrusion drying caused the most obvious damage to banana resistance starch and its crystal structure, and the product color was also the deepest.

Key words: banana, resistance starch, retention rate, drying
