The principal objective of current study was to evaluate the potential of near infrared reflectance spectroscopy (NIRS) as a non-destructive method for the prediction of the amylose and protein contents of un-hulled and brown rice in broad-based calibration models. The average amylose and protein co...

근적외선 분광분석법을 이용한 정량분석을 위해 우선적으로 얻어야 하는 것은? | NIRS을 이용한 정량분석을 위해 우선 원시 spectrum을 파일로 작성한 후 검량 식을 얻어야 한다. 검량 식은 원시 spectrum을 4가지 수 처리(math treatment)방법을 통하여 spectrum을 영역별로 중첩에서 생기는 noise와 bias를 최소화하였다. | |
근적외선 분광분석법의 이점은? | Infrared reflectance spectroscopy(NIRS; 근적외선 분광분석법)에 의한 분석방법은 시료를 비 파괴적으로 신속하게 정성 및 정량적인 분석이 가능하기 때문에 다량의 시료를 짧은 시간 내에 분석할 수 있어, 선진국에서는 쌀의 식미 평가를 NIRS 분석용 프로그램을 이용한 자동화시스템의 개발(7,8) 등 다양한 방법에 의한 가능성을 시도하고 있다(9-11). | |
쌀의 미질을 결정하는 중요한 이화학적 특성으로 보고된 요소는? | 쌀은 현미상태에서도 영양 성분이 주식에 가깝게 단백질, 지질, 탄수화물이 고루 분포되어 있으며, 기능성 성분도 다량 함유되어 있으며(1), 단백질 함량(2,3) 및 아밀로스(4,5)는 쌀의 미질을 결정하는 중요한 이화학적 특성으로 보고되었다(6). |
