Zusammenfassung:To provide a method for evaluating in non destructive manner, quality of laver.SOLUTION: There is provided a laver quality evaluation method comprises: a step (step S11) for radiating excitation light to laver; a step (step S21, 22) for detecting Raman scattering light of the laver with respect to the excitation light, detecting first Raman scattering light detected in a wave number area selected from 500 cm-1 to 1700 cm-1, and second Raman scattering light detected in a wave number area selected from 2500 cm-1 to 3300 cm-1; a step (step S31) for calculating a Raman scattering light relative strength ratio related to a strength ratio between the first Raman scattering light and the second Raman scattering light; and a step (step S41) for evaluating quality of the laver, on the basis of the Raman scattering light relative strength ratio.SELECTED DRAWING: Figure 2 【課題】海苔の品質を非破壊で評価する方法を提供する。【解決手段】海苔に、励起光を照射する工程(ステップS11)と、前記海苔の前記励起光に対するラマン散乱光を検出するものであり、500cm-1〜1700cm-1の範囲から選択される波数領域で検出される第一のラマン散乱光と、2500cm-1〜3300cm-1の範囲から選択される波数領域で検出される第二のラマン散乱光とを検出する工程(ステップS21,22)と、前記第一のラマン散乱光と前記第二のラマン散乱光との強度比に関するラマン散乱光相対強度比を算出する工程(ステップS31)と、前記ラマン散乱光相対強度比に基づいて、前記海苔の品質を評価する工程(ステップS41)とを、有する海苔の品質評価方法。【選択図】 図2
