Methods for lye peeling taniers (Xanthosoma spp.) were studied. Both medium- and large-size tubers could be peeled with high efficiency in 15% lye at 200° F (93° C), at a dipping time ranging from 6.5 to 10 min. Preheating the tubers in water for 30 min at 150, 160, and 170° F (66, 71, 97° C) increased peeling losses without effectively controlling the browning reaction. Tubers stored at room temperature (80° F; 26.7° C) remained in good processing condition 10 days. When stored for 25 days, suberization of wounds and decay caused high trimming losses. The main changes in chemical composition during storage were a decrease in moisture and starch content and a slight increase in acidity. An increase in shear-press force values was observed to take place concurrently with the decrease in moisture content.
