Abstract

This study investigates the effects of a variety of heat processes on the prebiotic properties of taro starch. The taro starch is treated by the annealing process (24 hours, 50oC), the heat moisture treatment (HMT, moisture 25%, 3 hours, 110oC), and the autoclaving (15 minutes, 121oC) - cooling (24 hours, 4oC) cycles with 1, 2, and 3 cycles. The results show that all treatments improve the prebiotic properties of taro starch. The modified taro starches (MTS) significantly increases their slow digestibility starch (SDS) and resistant starch (RS) content, while the in-vitro digestibility, very rapid digestible starch (VRDS), rapid digestible starch (RDS) are relatively decreased. However, the autoclaving-cooling two cycles (AC-2C) results in the MTS with the best prebiotic properties as shown by its high RS content, low digestibility, high prebiotic effect, high prebiotic index as well as prebiotics activity towards pathogenic bacteria. The AC-2C modified taro starch is very prospective to be used as a prebiotic candidate.
