摘要: 面条的质地是衡量面条品质的重要指标。本研究以108份不同马铃薯添加量的面条为样本,研究了马铃薯面条硬度与质地之间的关系。利用高光谱成像技术获取面条图像,并在此过程中分析纹理。建立了基于最小二乘法的校准和交叉验证模型。以72个面条为训练样本建立模型,以36个样本验证校准模型。校准模型和交叉验证模型的测定系数(R2CR2cv)分别为0.877和0.842,交叉验证模型的校准均方根误差(RMSEC)和交叉验证均方根误差(RMSECV)分别为11.405和13.166。预测集的确定系数(R2P)为0.988,预测均方根误差(RMSEP)为3.585。结果表明,该方法具有较强的鲁棒性和稳定性,可作为检测面条硬度的无损检测技术。

Abstract: The texture is an important index that indicates the noodle quality. In this research, the relationship between hardness and texture with respect to potato noodles was demonstrated by using 108 noodle samples with different amounts of potatoes. Noodle images would be captured by hyperspectral imaging technology and textures would be analyzed during that process. A calibration and cross-validation model were established based on the least squares regression method. 72 noodles as training samples were used to establish the model and the other 36 samples were used to verify the calibration model. The coefficient of determination (R2C and R2cv) values of the calibration model and cross-validation model were 0.877 and 0.842 while the root mean square error of calibration (RMSEC) and root mean square error of cross-validation (RMSECV) values were 11.405 and 13.166. The coefficient of determination (R2P) of the prediction set was 0.988 and the root mean square error of prediction (RMSEP) was 3.585. Results showed that the proposed determination method of potato noodle hardness was of high robustness and stability and could be used as a non-destructive detection technology for detecting the noodle hardness.
