Extraction and characterization of konjac glucomannan from elephant foot yam (Amorphophallus Paeoniifolius)

This scientific research investigates the optimal extraction method for obtaining Konjac Glucomannan from Elephant Foot Yam (Amorphophallus paeoniifolius) and characterizes its properties for potential applications in various industries. The study encompasses sample collection, preparation, extraction, and characterization processes conducted at Universiti Malaysia Kelantan. Konjac glucomannan, derived from the corm of Elephant Foot Yam, is a water-soluble dietary fibre known for its unique properties and potential health benefits. The extraction process involves pre treating the raw material, drying the corm using dry heat, and employing ethanol-based extraction techniques. Various parameters such as solvent concentration, extraction time, and temperature are optimized to maximize yield and quality. Characterization examinations include light microscopy analysis of konjac gel and powder, focusing on structural characteristics and particle size distribution. Additionally, X-ray Diffraction (XRD) is utilized to investigate the crystallographic structure of konjac powder, revealing insights into its structural characteristics. The study observes that the extracted konjac glucomannan exhibits water-absorbing properties, forming a stable gel structure suitable for various applications. Microscopic analysis reveals heterogeneous aggregates with irregular shapes and porous structures, contributing to its functional attributes. Furthermore, the study addresses the presence of calcium oxalate in Elephant Foot Yam and explores cooking techniques to mitigate its potential side effects, ensuring safe consumption. In conclusion, this research contributes to the scientific understanding of konjac glucomannan extraction and its potential applications in food, pharmaceuticals, and cosmetic industries. Additionally, insights into calcium oxalate content and mitigation strategies provide valuable information for safe consumption. Further optimization and research are warranted to enhance extraction efficiency and maximize the utilization of this sustainable resource.
