ABSTRACT

This study examined the effects of storage time, packaging condition, and their interaction on the nutritional and proximate quality of ground egusi over a three-month period. Ground egusi was stored in opaque and transparent hermetically sealed glass containers and analyzed at Months 1, 2, and 3 for minerals, vitamins, and proximate composition using Atomic Absorption Spectrophotometry (AAS), High-performance Liquid Chromatography (HPLC) and standard methods outlined by the Association of Official Analytical Chemist (AOAC), respectively. Results showed that storage time significantly influenced all measured parameters (p





Keywords: transparent, opaque, properties, vitamins, oxidation.
