摘要:
为了实现霉变稻谷脂肪酸含量无损、快速检测,该文研究应用可见/近红外光谱技术检测霉变稻谷的脂肪酸含量。考虑到直接选用霉变稻谷可见/近红外光谱数据构建脂肪酸含量预测模型存在建模费时、预测失准等问题,研究提出了霉变稻谷脂肪酸含量的可见/近红外优化校正模型。研究中通过光谱-理化值共生距离(sample set partitioning based on joint x-y distance, SPXY)算法结合偏最小二乘法初步分析了不同校正集样本预测霉变稻谷脂肪酸含量的差异;利用连续投影算法(SPA)提取了反映霉变稻谷脂肪酸含量变化的特征波段;采用偏最小二乘法(partial least square, PLS)和多元线性回归法(multivariable linear...
摘要(英文):
Fatty acids were stable metabolites and easily accumulated in paddies mould process which could better express mould extend of paddies. To achieve the non-destructive and rapid detection in fatty acid contents (FAC) for mould paddies, the detection of FAC for mould paddies was studied using the Visible/Near-infrared reflectance(Vis/NIR) spectral technology. The variety C liang-you 34156 late rice was used as paddy samples, which was obtained from Hunan Agricultural University. The mould paddy cultivating test and FAC determination experiments were carried out from October 15, 2014 to January 3...
