| 摘 要： | 研究小西瓜内部糖度分布规律的基础上提出了采用平均糖度、最高糖度和最低糖度表征小西瓜糖度的新方法。并采用便携式漫反射近红外分析仪，建立了快速测定小西瓜平均糖度，最高糖度和最低糖度近红外检测方法。最后将近红外检测方法与参考方法精度作了对比，结果表明漫反射近红外测量小西瓜糖度具有可行性。

| Abstract: | In the present paper,the distribution of sugar level within the mini-watermelon was studied,a new sugar characterization method of mini-watermelon using average sugar level,the highest sugar level and the lowest sugar level index is proposed.Feasibility of nondestructive determination of mini-watermenlon sugar level using diffuse reflectance spectroscopy information was investigated by an experiment.PLS models for measuring the 3 sugar levels were established.The results obtained by near infrared spectroscopy agreed with that of the new method established above. |
