Abstract:

Standard curves for determination of menthol responsible for the characteristic aroma of mint flavour, by different methods such as UV absorption spectroscopy, refractive index, near-infrared diffuse reflectance spectroscopy and gas chromatography were established and their linearity was analyzed to select reliable methods for determination of entrapment efficiency of mint flavour microcapsules. Results showed that UV absorption spectroscopy gave a determination coefficient of 0.9317, whereas determination coefficients of other three methods were all over 0.99, indicating a good linear correlation. Therefore, refractive index, near-infrared diffuse reflectance spectroscopy and gas chromatography can provide a relatively accurate determination for entrapment efficiency of mint flavour microcapsules.

Key words: menthol, refractive index, near-infrared diffuse reflectance spectroscopy, gas chromatography, entrapment efficiency
