Abstract
ABSTRACTThe extensive hand labor required in peeling Chinese waterchestnut corms has dicouraged their production in this country. After cutting the apical and basal ends from the corms, the peel was removed by softening in hot alkali, followed by wet brushing. The lignaceous pigmentation which stains the corms during peeling was decolorized by treatment with hydrogen peroxide. A nomograph to optimize peel softening in terms of alkali concentration, time and temperature is presented. This nomograph shows solutions to the equation 6.76 = [0.038 (°F) ‐ (6.51/% NaOH) ‐ (9.81/min of treatment)].
