Areca taro was processed using microwaving, frying, boiling, and steaming. Electron microscopy, color, texture, X-ray diffraction, Fourier transform infrared spectroscopy, pasting properties, water mobility, and flavor quality analyses were used to observe the areca taro. The experimental results showed that areca taro hardness and chewiness decreased after processing (P < .05). The peak viscosity of areca taro after boiling and steaming increased, whereas it decreased after microwaving and frying. Processing also decreased the setback, improved the stability of the cold paste, and made aging more difficult (P < .05). After different heat treatments, the bound water content of areca taro decreased, whereas the semi-bound and free water contents increased. Additionally, the relative crystallinity and short-range-ordered structures reduced under all treatments. Furthermore, fried and steamed areca taro had higher sensory scores, owing to their moderate aroma, hardness, and viscosity.
