This study conducted chemical and physical hazard analysis on the acidity, peroxide value, color removal, and limit criteria of metal detector of roasted laver. The Hunter color L- and a-value of roasted laver was higher than the control, and the b-value was higher at $400^{\circ}C$. The limit criteria establish by metal detector was determined to a sensitivity of 60 because it detected 100% in a sensitivity of 60 to Fe and Sus. The acidity and peroxide values increased with increasing temperature. These results confirmed that roasted laver is safe when roasted to $300^{\circ}C$ for 5 seconds.
