本計畫選用校園午餐常見漁獲物 (鯖魚、白帶魚、吳郭魚) 及三章一 Q 政策所希望 推行 進入校園漁獲物 (虱目魚),來進行測定。四種漁獲物生鮮狀態品質指標 (VBN 值在 10.19~17.60mg/100g 之間;TBA 值在 0.42~0.71mg/kg 之間;Histamine 值 在 0.71~6.02ppm 之間;K 值在 3.18~12.2% 之間;Torrymeter 值在 9.30~14.24 之間),顯示漁獲物品質皆處於良好的狀態。隨著儲存的過程中,VBN、K 值有上升 趨勢,而 Torrymeter 值有下降趨勢。此外利用近紅外光 (NIR) 檢測技術與品質指 標數值結合,可以得知各品質之標相關係數 (VBN 介於 0.51~0.94 之間;TBA 介於 0.62~0.87 之間;Histamine 介於 0.32~0.83 之間;K值介於 0.70~0.93 之間 ;Torrymeter 值介於 0.80~0.97 之間),表示有潛力利用該方法對於漁獲物品質進 行測量及分析。另外從 Matlab 分析結果得知,以 VBN 25mg/100g 為界線,可以有 良好的辨識率 (81%)。

研究報告摘要(英)


This project selects common catches (mackerel, whitefish, and talipi) during school lunch and milkfish that are expected to be implemented by the three chapter one Q policy for determination. Four quality indicators for the fresh state  (VBN value is between 10.19~17.60mg/100g; TBA value is between 0.42~0.71mg/kg; Histamine value is between 0.71~6.02ppm; K value is between 3.18~12.2%; Torrymeter value is between 9.30~14.24), indicating that the quality of the catch is in good condition. With the storage process, the VBN and K values have an upward trend, while the Torrymeter value has a downward trend. In addition, using near-infrared light (NIR) detection technology combined with quality index values, we can know the standard correlation coefficient of each quality (VBN is between 0.51 and 0.94; TBA is between 0.62 and 0.87; Histamine is between 0.32 and 0.83 The value of K is between 0.70~0.93; the value of Torrymeter is between 0.80~0.97), indicating the potential to use this method to measure and analyze the quality of the catch. In addition, according to the results of Matlab, with VBN 25mg/100g as the boundary, a good recognition rate (81%) can be obtained.
