Leren (Calathea allouia) tuber is very palatable with high carbohydrate content, protein, fiber, minerals, essential amino acids but low levels of lipids. However, it's quickly decomposed during post-havest. Chitosan has been demonstrated to be an eco-friendly alternative to synthetic fungicides for the management of post-harvest diseases on horticultural crop products. Objective of this study focused on the efficacy of chitosan coating in different concentrations (0.05, 0.1, 0.15, 0.2 and 0.25) onleren tubers during six months of storage at ambient temperature. In every two month-interval, treated leren tubers were randomly sampled to estimate weight loss (), firmness (), decay percentage and soluble solid (oBrix). This study was conducted in 2019 in Labone Scientific Co. Ltd, Vietnam. Our results showed that 0.2 of chitosan coating could effectively preserve the physico-chemical attributes of leren tubers during six months of storage. Chitosan had a potential as a substitute for synthetic fungicides to reduce post-harvest losses in leren tubers.
