Abstract

Taro (Colocasis esculenta) tubers have high contents of oxalate (341-364 mg/100 g as oxalic acid on dry basis). Consumption of high oxalate foods can cause irritation of the mouth and increase the risk for renal calcium oxalate formation and affect Ca absorption. In this study, effects of blanching (with or without NaCl) and EDTA treatments (soaking and blanching) on oxalate contents of taro were investigated. Blanching of taro with NaCl decreased oxalate (as oxalic acid) contents by up to 37.2%. However, the best method for decreasing oxalate was blanching with EDTA (0.1mM), which reduced oxalate content by up to 80%.
