METHOD FOR DETECTING AKAME LAVER

摘要

PURPOSE:To provide a method for detecting AKAME laver (not genuine laver) which can agree with the paneller's (inspector's) judgment. CONSTITUTION:A reflectance of a wavelength in a vicinity of 470nm and 630nm of dry laver is measured to obtain a ratio of the reflectances of these two wavelengths, and it is compared with a calibration curve that is the evaluation criterion to detect AKAME laver.
