Title

ALPHA AMYLASE ACTIVITY AND SPROUTING DURING SHORT TERM STORAGE OF TARO CORMS

Pages

  1053-1063

Abstract

 The objective of this study was to investigate taro [COLOCASIA ESCULENTA (L.) Schott] corm quality as determined by changes in starch morphology and degradation during storage after harvest. Starch is the major nutrient component of taro corms and its quality in corms that are stored as planting material or consumption has not been fully explained. Scanning ELECTRON MICROSCOPY was used to examine the changes that occur to the surface morphology of STARCH GRANULES in corms of taro LANDRACEs, Dumbe-dumbe, Mgingqeniand Pitshi, stored at cool (12oC) and ambient (20oC) temperatures. Alphaamylase activity and sprouting were used as indicators of changes in the STARCH GRANULES, and hence corm quality, during storage in polyethylene bags, card boxes, and mesh bags. The degradation of STARCH GRANULES, alpha amylase activity, and sprouting increased over storage time and varied with LANDRACEs, storage material, and temperature. Overall, there was 23% more alpha-amylase activity and 67% more sprouting at 20ºC compared with 12oC. With respect to storage material, polyethylene bags showed the highest alpha-amylase activity (0.18 EU 0.1 g-1) followed by card boxes (0.15 EU mg-1 0.1 g-1) and mesh bags (0.14 EU mg-1 0.1 g-1). A similar, but more pronounced, trend was observed for sprouting. The findings have implications for selection of storage material for food and propagule storage.
