Abstract

The geographical origin of Tricholoma matsutake mushrooms was studied using near-infrared spectroscopy. Modified partial least-square regression analyses were used to discriminate geographical origin. Two-hundred fifty-six of 259 actual domestic Tricholoma matsutake were classified as domestic produce, Sixty of 81 actual imported mushrooms were correctly classified as imported, while the other 21 imported from North Korea were not clearly classified. The accuracy of geographical origin discrimination was 92.94% The correlation coefficient, standard error of calibration, and standard error of prediction from modified partial least-square regression analysis were 0.84, 15.10% and 18.30% respectively.

근적외선 분광광도법을 이용하여 송이버섯의 원산지 판별을 시험하였다. 259개의 국내산 시료중 256개는 국내산으로 판별하였고(98.84%) 수입산 81개중 60개는 수입산으로 판별하였으나(74.07%) 21개의 북한산은 판별하기가 모호하여 잘못 판정한 것으로 간주할 때 시료 판별의 전체정확도는 92.94%로 나타났다. MPLS에 따른 분석의 경우 상관계수는 0.84, 검량선의 표준오차는 15.10%, 예측 표준오차는 18.30% 이었다.
