The Effect of NaOH Concentration on The Physical and Chemical Properties of Jerbung Shrimp (Fenneropenaeus Merguiensis de Man) Waste Powder

Abstract

This research was conducted to determine the effect of NaOH concentration on the physical and chemical properties of shrimp waste powder. This research used a Completely Randomized Design (CRD) with NaOH concentration treatment consisting of 5 levels (1%, 1.25%, 1.5%, 1.75% and 2%) and 4 repitition. The data obtained were analyzed statistically using analysis of variance and followed by Duncan's New Multiple Range Test (DnMRT) when necessary. The research shows that the NaOH concentration has a significant effect on the ash content, protein content, L* and b* values, but has no significant effect on the water content, fat content, solubility and a* values. The best characteristics of shrimp waste powder is obtained using NaOH 1.5% which produces powder with 4.22% water, 39.27% ash, 18.37% protein, 12.43% fat, solubility of 4. 04%, L* value 48.37, a* value 10.92 and b* value 21.47.
