Correlation between Non-destructive Quality Evaluation Parameters and Spectral Reflectance of Apple

사과의 분광반사(分光反射) 특성(特性)과 비파괴(非破壞) 품질평가인자(品質評價因子)와의 상관관계(相關關係) 구명(究明)

Optical properties of fruits can provide information for nondestructive quality evaluation. An attempt is made here to develop an optical method for quality evaluation of apple using the spectral reflectance of its surface. Optical fiber was used to transmit light conveniently from light source to sample and sample to detector. Spectral reflectances of two types of Fuji variety-one of which was exposed to the sunlight directly (non-bagging) and the other was wrapped with bag (bagging) - were investigated from the wavelength ranging of 400nm to 700nm. The relationships between reflectance characteristics and quality indices such as chlorophyll content, anthocyanin content, and soluble solids were analyzed.
