    摘要:

    為了探討高光譜圖像技術(shù)對不同儲存時間和取樣部位的牛肉顏色檢測的可行性,采集具有代表性的牛肉后腿,、里脊和背脊共82個牛肉樣品的高光譜圖像,,并測量其亮度、紅度,、黃度和飽和度等顏色參數(shù),。選取感興趣區(qū)域獲取樣品代表性光譜,通過選擇適宜的譜區(qū)范圍和預處理方法,,建立并評價了預測各顏色參數(shù)的偏最小二乘校正模型,。對于亮度、紅度,、黃度和飽和度,,校正集的相關(guān)系數(shù)分別為0.80、0.91,、0.91和0.93,,校正標準差分別為2.23、1.18,、0.82和1.12,,預測集的相關(guān)系數(shù)分別為0.92、0.88,、0.87和0.89,,預測標準差分別為1.66、1.45,、0.80和1.27,。研究結(jié)果表明,高光譜圖像技術(shù)可用于快速無損檢測不同儲存時間下,、不同部位的牛肉顏色,。

    Abstract:

    In order to explore the feasibility of hyperspectral imaging technique to estimate beef color parameters under different storage time and sampling positions, hyperspectral images of 82 representative beef samples were acquired. Color parameters, including brightness (L*), redness (a*), yellowness (b*) and saturation (C*) were also determined. Their representative spectra were obtained by selecting regions of interest (ROIs). By comparing and choosing appropriate spectral regions and pretreatment methods, optimum partial least squares (PLS) calibration models of each beef color parameters were established and evaluated, respectively. As for L*, a*, b* and C*, the correlation coefficients of calibration were 0.80, 0.91, 0.91 and 0.93, and root mean square errors of calibration were 2.23, 1.18, 0.82 and 1.12, respectively. The correlation coefficients of prediction were 0.92, 0.88, 0.87 and 0.89, and root mean square errors of prediction were 1.66, 1.45, 0.80 and 1.27, respectively. The results showed that hyperspectral imaging technique could be used to rapidly and non-destructively analyze beef color parameters under different storage time and sampling positions.
