METHOD FOR MEASURING REDNESS OF RED PEPPER PASTE TO OBJECTIVELY SHOW REDNESS OF RED PEPPER PASTE BY USING EXTINCTION DEGREE OF RED PIGMENT IN RED PEPPER PASTE

摘要

PURPOSE: A redness measurement method of red pepper paste is provided to objectively show the redness of the red pepper paste by measuring the extinction degree of a red pigment inside the red pepper paste and by calculating the redness of the red pepper paste with an ASTA(Astaxanthin) unit. CONSTITUTION: A red pepper paste sample is mixed with a silica powder and dried. A red pigment of the red pepper paste is extracted by soaking the mixed material of the red pepper paste sample and the silica powder in a solvent solution. The solvent solution containing the red pigment of the red pepper paste is filtered and the filtered solution is made in a constant volume. The extinction degree of the filtered solution is measured. The redness of the red pepper paste is measured from the measured extinction degree of the filtered solution. Thereby, the redness measurement method of the red pepper paste is usefully used for a production, the quality management and the quality evaluation of the red pepper paste.
