The flavour and fragrance industry is a key part of the worldwide specialty chemicals industry, yet most technical recruits have minimal exposure to flavours and fragrances before recruitment. The analytical chemistry of flavour and fragrance materials presents specific challenges to the analytical chemist, as most of the chemicals involved are highly volatile, present in very small amoun 606 $aFlavor$xAnalysis 606 $aFlavoring essences$xAnalysis 606 $aFlavor$xBiotechnology 615 0$aFlavor$xAnalysis. 615 0$aFlavoring essences$xAnalysis. 615 0$aFlavor$xBiotechnology. 676 $a664/.07 701 $aGoodner$b Kevin$01841131 701 $aRousseff$b Russell$01841132 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911018885003321 996 $aPractical analysis of flavor and fragrance materials$94420758 997 $aUNINA
