A combination of two specifically different pigments, phycoerythrine and chlorophyll, gives the laver shining black color. This shining black color is the dominant factor in deciding tile quality of the dried product of laver (dried laver). Therefore, this experiment was carried out to know the effect of tannic acid as a pigment fixing agent. Raw laver, Porphyra spp., was treated with tannic acid solutions to prevent dissolution of biliproteins especially phycoerythrine in to the fresh water. This danger is mostly revealed when the chopped and shredded lavers are suspended in fresh water before the laver sheets are finally made. The influence of mechanical damage with different diameters of chopper plate on dissolution of the pigment was also mentioned. Theresultsobtainedareasfollows: 1. When the raw laver not yet chopped was stored for 3 days at $1\~5^{\circ}C$ in a dark place, the contents of chlorophyll and phycoerythrine decreased. 2. In the organoleptic test (Table 2,3,4),: the dried laver with a good coloration and surface gloss was obtained from a chopper plate with 7 mm or 3 mm. 3. A tannic acid solution of $0.02\%$ and $0.004\%$ appeared effective In preventing dissolution of phycoerythrine.
