    table it was found that the calcium oxalate content in fresh tuber were 0.14% in elephant foot yam‚ in karunai kizhangu 0.25% and in taro 0.20 percent respectively. The processed (soaking the tubers in citric acid followed by blanching‚ drying & roasting) tuber flour was subjected to determine the presence of calcium oxalate. It was found that elephant foot yam flour had 0.05%‚ karunai kizhangu flour contained 0.09% and in taro flour had 0.08 percent calcium oxalate. The reduction in acridity was noticed
