“…Therefore, a calibration model is required to establish the relationship between the component of interest and the spectrum. In fact, a combination of near infrared spectroscopy and calibration model has been successfully implemented in non-destructive SSC assessment of various fruits such as apple (Ventura et al, 1998;Peirs et al, 2003;Liu and Ying, 2004;Alamar et al, 2007;Peng and Lu, 2007;Zou et al, 2007;Fan et al, 2009;Zhu et al, 2009), citrus (Lu et al, 2006;Zude et al, 2008), loquat (Fu et al, 2009) mango He, 2009), mangosteen (Teerachaichayut et al, 2007), melon (Long, 2005;Tian et al, 2007), and pineapple (Pathaveerat et al, 2008).…”
