本发明公开了一种香蕉可溶性固形物含量的可见/近红外光谱无损检测方法，针对已知可溶性固形物含量的香蕉样品，用可见/近红外光谱仪采集香蕉样品表面的光谱信息，获得各种样本的光谱代表信息后，还需对光谱信息进行预处理；将香蕉光谱数据导入The Unscrambler X 10.1中，进行样本光谱数据的预处理；利用导数矫正法进行特征波长的提取，基于一阶微分提取的特征波长段对应的光谱数据建立多元线性回归模型，记录该模型下的衡量指标，最终选定特征波段为1230nm‑1440nm；建立数学模型后，需要有各项指标对模型的准确性、可靠性、稳定性和预测能力作出衡量和评价。本发明可以更加客观、准确实现香蕉可溶性固形物含量的快速检测，从而实现香蕉采摘期的快速无损判定。
