Hyperspectral laser-induced fluorescence imaging for assessing apple fruit quality

Recent applications of Chemical Imaging to pharmaceutical process monitoring and quality control

“…Some authors have remarked that conventional chemometric methods such as PCA and PLS may not be suitable for analysing Chemical Images, since these techniques were developed for analysing single spectra [58] and [59]. To overcome the limitations of conventional chemometric approaches, a number of novel chemometric methods have been proposed.…”

Vis/NIR hyperspectral imaging for detection of hidden bruises on kiwifruits

“…X-ray imaging has Supported by the National Natural Science Foundation of China, Grant No. 30771243. been used to inspect internal quality, such as water core, bruise of apple (Shahin et al 1999(Shahin et al , 2002bKim et al 2000), weevil-infested mango (Thomas & Kannan 1995), and rotten onion (Shahin et al 2002a), etc. In the recent years, hyperspectral imaging has been investigated for the estimation of quality and safety of poultry (Liu et al 2003;Park et al 2006Park et al , 2007, fruits (Lu et al 1999;Lu 2003;Mehl et al 2004;Xing & Baerdemaeker 2005;Xing et al 2005Xing et al , 2007Noh & Lu 2007;Qin et al 2009), vegetables (Liu et al 2005;Ariana et al 2006), and milk (Qin & Lu 2007). Lu et al (1999) have studied hyperspectral imaging for detecting bruises on three cultivars of apples in the spectral region between 450 nm and 900 nm.…”

Estimation of Optical Properties in Postharvest and Processing Technology

“…According to the results, 12-13% effect of drought stress was observed compared to the sufficiently irrigated samples. Blue laser (408 nm) induced chlorophyll fluorescence was evaluated on 'Golden Delicious' apples (Noh & Lu, 2007). Fruit firmness, SSC, titratable acid content, skin and flesh color (chroma and hue) were predicted.…”
