“…NIR spectroscopy measures molecular vibrations that, in contrast to midinfrared (MIR) radiation, can be transmitted through quartzbased optical fibers, enabling simple and flexible sampling on the process line. Previous studies have shown that NIR spectroscopy has great potential as an analytical technique for the determination of homogeneity of powder blends (Scotter, 1990;Wargo and Drennen, 1996;Muzzio, Robinson, Wightman and Brone, 1997;Luner, Majuru, Seyer and Kemper, 2000;ElHagrasy, Morris, D'Amico, Lodder and Drennen, 2003) and quantification of lactose content (Kaffa, Norris, Kulscár and Draskovits, 1982;Baer, Frank, Loewenstein and Birth, 1983;Buckton, Yonemochi, Hammond and Moffat, 1998;Laporte and Paquin, 1999;Lane and Buckton, 2000;Tarkosova and Copikova, 2000;Hogan and Buckton, 2001) in various food systems. NIR spectrum provides characteristic information on the internal constituents of the sample, so it has been widely used in dispensation, such as component analysis of Chinese herbal plants Angelicae gigantis radix (Woo et al, 2005), rhubarb (Zhang and Tang, 2005), licorice (Wang et al, 2007), Panax species (Chen et al, 2011), and Lonicera japonica (Wu et al, 2012), as well as a content detection of active pharmaceutical ingredients (APIs) in tablets (Paris et al, 2006;Jamrógiewicz, 2012 andPorfire et al, 2012).…”
