The proposed postharvest handling method increases the quality of corn (Zea mays L.) grains

Corn (Zea mays L.) is a potential commodity to support food self-sufficiency in Indonesia. Some regions use corn as an alternative food to substitute rice. However, the quality is still low because of the poor postharvest handling. The objective of the present work was therefore to compare the quality of corn grains produced by the traditional method and the proposed postharvest handling method. The present work investigated the differences in postharvest handling methods in harvesting, drying, grain removal, packing, and storage steps. The observed parameters were moisture, damaged grains, broken grains, and aflatoxin level. Moisture content was measured using a moisture analyser, while damaged and cracked grains were determined after shelling. Aflatoxin levels were analysed using High-Performance Liquid Chromatography (HPLC). Grains subjected to the proposed handling method showed an increased quality. The traditional method resulted in grains with a higher level of water content and aflatoxin level, with damaged and broken grains as compared to the proposed postharvest handling method. The proposed postharvest handling method grains met the Indonesian National and International Standard's requirements for corn grains. (C) All Rights Reserved
