Abstract: The feasibility of non destructive quantitative determination of sugar and acid in intact apple by near infrared spectrometer(NIRS)was investigated.Through examination of the second derivatives of the spectra,we found that 914nm,950nm,897nm,and 912nm are the first characteristic wavelengths of sucrose,glucose,fructose and malic acid,respectively.Compared with the calibration data by high performance liquid chromatography,the results obtained at these wavelengths bear the multi correlative coefficients of 0.997,0.992,0.992,0.996 correspondingly,and the standard errors for the test samples are 0.085,0.057,0178,and 0.021,respectively.This indicates that NIRS is sufficiently precise and reliable for practical use in the quantitation of sugars and acids in intact apples.
