Objective of this work was to study possibility for prediction of total soluble solids (TSS) from total of 400 lychee fruits by using near infrared spectroscopy (NIRS) technique in transmittance mode (wavelenagth regions of 650-955 nm) and interactance mode (wavelength regions of 600-1100 nm). Calibration and prediction models were constructed using Partial Least Square Regression (PLSR). The best prediction was obtained from model developed from transmittance spectra. Prediction model for Chakaphat variety having a multiple correlation coefficient R of 0.940 and root mean square error of prediction (RMSEP) of 0.500 performed better than the prediction model for Kimjeng variety with R of 0.829 and RMSEP of 0.489. The prediction model for the combined varieties exhibited R of 0.936 and RMSEP of 0.358. This feasibility study indicated that transmittance NIRS could be used to accurately determine total soluble solid content in intact lychee without destruction.
