在(zai)(zai)(zai)肉品(pin)(pin)評價(jia)過(guo)程(cheng)中(zhong),氣(qi)(qi)味(wei)(wei)(wei)是(shi)一個很重要的(de)(de)評價(jia)指標(biao),其直接相關于(yu)(yu)肉制品(pin)(pin)的(de)(de)安全控(kong)制。氣(qi)(qi)味(wei)(wei)(wei)是(shi)揮發(fa)性的(de)(de)風味(wei)(wei)(wei)物(wu)質刺激鼻腔(qiang)嗅覺感(gan)受器而產生。在(zai)(zai)(zai)肉品(pin)(pin)工業中(zhong),電(dian)子(zi)鼻(氣(qi)(qi)味(wei)(wei)(wei)分(fen)析系統)主要對(dui)肉類(lei)食品(pin)(pin)的(de)(de)揮發(fa)性氣(qi)(qi)味(wei)(wei)(wei)進行(xing)(xing)識別(bie)和分(fen)類(lei),終對(dui)產品(pin)(pin)進行(xing)(xing)質量分(fen)級和新鮮度(du)判別(bie)。此(ci)外(wai),電(dian)子(zi)鼻(氣(qi)(qi)味(wei)(wei)(wei)分(fen)析系統)也被應(ying)用(yong)于(yu)(yu)肉品(pin)(pin)加(jia)工生產線上連續監測中(zhong),用(yong)于(yu)(yu)工廠在(zai)(zai)(zai)加(jia)工過(guo)程(cheng)中(zhong)肉制品(pin)(pin)的(de)(de)安全控(kong)制。除了肉品(pin)(pin)的(de)(de)安全度(du)控(kong)制外(wai),對(dui)于(yu)(yu)某(mou)些傳統干腌火(huo)腿制作過(guo)程(cheng)中(zhong)藥經過(guo)一段時間較長(chang)的(de)(de)成(cheng)熟期,才可(ke)以行(xing)(xing)程(cheng)*的(de)(de)口感(gan)和風味(wei)(wei)(wei),此(ci)時電(dian)子(zi)鼻(氣(qi)(qi)味(wei)(wei)(wei)分(fen)析系統)也可(ke)用(yong)于(yu)(yu)判斷某(mou)些肉制品(pin)(pin)成(cheng)熟期。電(dian)子(zi)鼻(氣(qi)(qi)味(wei)(wei)(wei)分(fen)析系統)在(zai)(zai)(zai)豬肉氣(qi)(qi)味(wei)(wei)(wei)檢測方面的(de)(de)應(ying)用(yong),例(li)如:

1.電子鼻(氣味分(fen)析系(xi)統)用于不同處(chu)理的新鮮豬(zhu)肉的區分(fen)檢測

2.電子鼻(氣味(wei)分析系統)用于豬(zhu)肉風味(wei)的分析

3.電子(zi)鼻(氣(qi)味(wei)分析(xi)系統)用于火腿腸的(de)(de)肉質摻假的(de)(de)判斷(duan)分析(xi)

4.電子鼻(氣味分析(xi)系統(tong))用于豬肉(rou)原料肉(rou)對(dui)肉(rou)制品風味的(de)影(ying)響(xiang)

5.電子鼻(氣味(wei)分析系(xi)統)在發酵肉(rou)制(zhi)品(pin)品(pin)質檢驗(yan)中的應用

6.電子鼻(氣味分析系統)在金華火腿品質檢測(ce)中的應用及原料(liao)肉與(yu)火腿香精的替代(dai)性使用

7.電子(zi)鼻(bi)(氣味分析系統(tong))在(zai)宣(xuan)威火腿品質檢(jian)測(ce)中的應用

8.電子(zi)鼻(氣味分(fen)析系統)在肉類變質鑒別中的(de)應用

9.電子(zi)鼻(bi)(氣味分析系統)在揮發性(xing)鹽基氮檢測中的應用

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S3S4S7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%。
