研究了高光谱成像(HSI)系统(380-1000 nm)对即食香肠在35℃下储存5天内三磷酸腺苷(ATP)含量的非侵入性估计。根据回归系数值选择了10个重要波长(385、390、395、505、580、670、745、780、855和955 nm)。用全波长和最佳波长建立的预测决定系数(r(P)(2))分别高达0.8324和0.8606。通过R统计开发的化学成像，首次显示了香肠中ATP含量的浓度和位置。将HSI和多变量分析相结合，可以量化和可视化ATP在贮藏过程中的动态变化，在加工肉类行业的实时检测中具有很大的潜力。
A hyperspectral imaging (HSI) system (380-1000 nm) was investigated for non-invasively estimating adenosine triphosphate (ATP) content in ready-to-eat sausages during 5 days storage at 35 degrees C. A set of pretreated combinations were carried out on preprocessing the spectra to improve the performance of partial least squares regression (PLSR). According to the regression coefficient values, ten important wavelengths (385, 390, 395, 505, 580, 670, 745, 780, 855, and 955 nm) were selected in this study. PLSR models developed using full wavelengths and optimal wavelengths showed the prediction coefficient of determination (r(p)(2)) up to 0.8324 and 0.8606, respectively. The concentration and location of the ATP content in sausages were for the first time displayed via chemical imaging developed by R statistics. Combining HSI and multivariate analysis can quantify and visualize ATP dynamic changes during storage and a great potential in the processed meat industry for real-time inspection.
