The feasibility of predicting the sugar content of Okinawan grown pineapples and mangoes was studied using the specific NIR absorption bands. Therefore, components of pineapples and mangoes were mainly water, cellulose and sugar, the calibration curve of predicting the sugar content of pineapples and mangoes have been made using the absorption bands of water, cellulose and sugar. When 4 specific bands at 958, 978, 918, and 844nm were used to predict the sugar content of pineapple, SEP of sugar content of pineapples harvested in 1992, 1993, 1995 and 1995 were 0.66, 0.55, 0.66 and 0.63, and BIAS were -0.26, -0.26, 0.22 and 0.16. Respectively, in the case of mangoes with 4 specific bands at 958, 978, 918 and 878nm, SEP were 0.70, 0.51, 0.64 and 0.47, and BIAS were 0.19, 0.13, -0.16 and 0.16. Good correlation between chemical analysis and NIR values from using absorption bands on water, cellulose and sugar were obtained.
