In this paper a fast non-destructive analytical method to measure various nutrients in the intact strawberry--Near infrared Spectrometry(NIRs)was introduced.Using this method the contents of six nutrients including sucrose,glucose, fructose,citric acid,malic acid and vitamin C were determined simultaneously.The multiple correlation coefficients between these values and those obtained on high performance liquid chromatography (HPLC) were 0 9920, 0.9914, 0.9888, 0.9954, 0.9949 and 0.9980,respectively. The standard'errors of calibration were 0.021, 0.035, 0.065,0.044, 0.029,0.727, respectively.These results showed that NIRs had a similiar accuracy to HPLC. However since it is faster and non-destructive,and dose not require any sample preparation and expensive chemicals, NIRs can be favourably introduced and applied to the nutrient analysis and quality determination of the intact strawberry.
