| 摘 要： | 利用红外光谱法对天津产地玫瑰香葡萄酒识别鉴定,提出了用支持向量机(SVM)算法对干白葡萄酒红外光谱图进行分析,详细介绍了干白葡萄酒谱图的预处理过程,包括基线校正、消除噪声、标准归一化和去除异常样本点。选取了不同产地的玫瑰香原酒样品511个、贵人香原酒样品438个、霞多丽原酒样品307个、白玉霓原酒样品29个、白羽原酒样品44个、龙眼原酒样品31个、泽香原酒样品79个,针对不同分类将80%样品谱图用SVM建立分类模型,并用剩余20%样品谱图对这些模型进行验证,实验结果表明该方法行之有效,不同葡萄品种干白葡萄酒模型正确率、识别率和拒绝率达到97%以上,不同产地玫瑰香干白葡萄酒正确率、识别率和拒绝率达到98%以上。该方法可以对天津产地玫瑰香葡萄酒进行定性识别鉴定。 |
