Abstract

Internal and external qualities of mangoes during storage were evaluated by hyperspectral spectroscopy. Green mature mangoes were harvested in Okinawa Prefecture, Japan, and stored for 14 d at 27°C [relative humidity 90%]. Spectral reflectance (380 – 1000 nm), anthocyanin concentration, chlorophyll concentration in skin, and soluble solid content (SSC) in flesh were measured during storage. Anthocyanin concentration and SSC were nondestructively determined with correlation coefficients of 0.88 [root mean square error of cross validation (RMSECV) 2.96 mg·100 g f.w.−1] and 0.73 (RMSECV 0.98%), respectively, using partial least squares regression (PLSR) models. The proposed nondestructive method may be effective for evaluating internal and external qualities of mangoes simultaneously.
