Abstract

The objective of this research was to analyze the effects of packaging methods and storage duration on the characteristics of pressed generic nata de coco. The research method employed a Factorial Ramdomized Block Design (FRBD) with two treatment factors : packaging method (A1 = vacuum, A2 = non-vacuum) and storage duration (B1 = 1 week, B2 = 2 weeks, B3 = 3 weeks, B4 = 4 weeks) at cold and room temperatures. Each treatment was conducted with three replications. The observed parameters included chemical characteristics (moisture content and pH), physical characteristics (texture, weight loss, degree of expansion upon rehydration and water absorption) and sensory characteristics using paired comparison tests for texture and aroma. The result indicated that packaging method significantly affected pH at both cod and room temperature storage. Storage duration significantly influenced moisture content at room temperature and pH at both room and cold temperatures. The interaction between packaging method and storage duration showed no significant effect on moisture content, pH, texture, water absorption, degree of expansion upon rehydration and weight loss for both storage conditions. The best result were obtained from treatment A2B4 (non vacuum, 4 weeks storage), demonstrating that the pressed generic nata de coco packaged in nylon plastic without vacuum could last for 4 weeks at both room and cold temperatures. Keywords : generic nata de coco, packaging, pressing, storage
