關(guan)于-電子鼻(氣味分析系統)檢測豬肉氣味差異研(yan)究中(zhong)的應用(yong),在此列出幾(ji)個案例:
電子鼻(氣(qi)味分(fen)析(xi)系(xi)統)用于肉(rou)質鑒別方面的應用
肉質鑒(jian)別:由不同(tong)肉樣品(pin)傳感器響應(ying)雷達(da)圖(tu)可知,1-6個(ge)樣品(pin)的雷達(da)圖(tu)有所不同(tong)。對于(yu)1-4號豬肉樣品(pin)而(er)言(yan),其氣味差異主要體現在S3、S4、S7這幾個(ge)傳(chuan)感(gan)器上(shang),對于整(zheng)個(ge)1-6號肉樣品而言其氣味差(cha)異主要體(ti)現在S2、S3、S4、S5、S6、S7。在(zai)圖中(zhong)DI值為92.28%,說明主(zhu)成(cheng)(cheng)分(fen)分(fen)析法的整體區分(fen)效果很好(hao),主(zhu)成(cheng)(cheng)分(fen)1和主(zhu)成(cheng)(cheng)分(fen)2的總貢獻率(lv)為98.55%,可以代表樣(yang)品(pin)全部信(xin)息(xi)。圖(tu)中,各樣(yang)品(pin)的重復性較好。此外,樣(yang)品(pin)1-4聚集在一(yi)起(qi),5,6號樣品分別在各自的區域,也與實際結(jie)果(1-4號(hao)為(wei)同一(yi)種(zhong)(zhong)(zhong)類,5號(hao)為(wei)一(yi)種(zhong)(zhong)(zhong)肉(rou),6號(hao)為(wei)一(yi)種(zhong)(zhong)(zhong)肉(rou))一(yi)致,所(suo)以電子鼻可(ke)用于肉(rou)品(pin)(pin)種(zhong)(zhong)(zhong)的(de)區分。建立肉(rou)的(de)模型(xing)后,對(dui)未(wei)知樣(yang)品(pin)(pin)進(jin)行檢驗(yan):從判(pan)別函數分析結果可(ke)以看(kan)出,預測樣(yang)品(pin)(pin)X為(wei)3號(hao)樣(yang)品(pin)(pin),樣(yang)品(pin)(pin)Y為(wei)5號(hao)樣(yang)品(pin)(pin),預測準(zhun)確率100%。
后(hou),電子鼻(氣(qi)味(wei)分析系統)含有多元數理(li)統(tong)計系統(tong):對(dui)象整體(ti)品質差異的區分(fen)檢驗(PCA)、原(yuan)產(chan)地保(bao)護產(chan)品以及品牌產(chan)品真偽(wei)辨(bian)識(SIMCA、PLS-DA)、產品(pin)品(pin)質等級評(ping)定(DFA)、樣品感官屬(shu)性以及理化指(zhi)標的(de)快(kuai)速反演(PLS)、產品貨架時間的評價(PCA、PLS);算法多樣:含有Euclidean Dis歐氏距離(li)、CORRELATION相關系數、MAHALANOBIS馬氏距離(li)、DP dis個體識(shi)別率、DI dis區分指(zhi)數、Scores Dd得(de)分值分離度、Eigenvalue Dd特征值分離度等算(suan)法(fa),可(ke)對肉制品產品氣味,例如電子鼻(bi)(氣味(wei)分析系統)檢測豬肉氣味差異研究,產生重要(yao)作用(yong)。
