荔枝在不同红外辐射源下真空干燥优化试验（Optimization Test of Litchi Vacuum Drying under Different Infrared Radiation Sources）
荔枝 红外辐射源 真空
2009/5/22
通过不同红外辐射源真空干燥荔枝试验以及干燥工艺品质试验，表明果肉与辐射源光谱匹配显著影响干燥速率，真空度、辐射热流密度的匹配影响干燥速率及干燥品质；采用辐射源SZ、辐射距离120mm、加热/缓苏时间15min/15min、真空度0.02MPa的干燥工艺，干燥速率与干果品质综合评价最优。
脐橙VC含量近红外光谱消噪小波优化（Wavelet Optimization for Near-infrared Spectra Denoising of Vitamin C Content of Umbilical Orange）
脐橙 近红外光谱 小波基
2009/5/22
运用db1～db10等10个小波基4尺度分解对120个赣州脐橙样品的近红外光谱进行消噪处理，分别建立了各种小波消噪光谱的脐橙维生素C(VC)含量的PLS模型。通过PLS模型预测精度比较表明：所有db小波基变换都能有效消除脐橙VC近红外光谱噪声，PLS模型预测精度均高于不处理光谱建立的模型预测精度。其中，消噪效果最好的小波基是db5，模型预测值与实测值的相关系数R达到0.9427、内部交叉验证均方差...
