HC Example 2 The goal of the project described here is to use HCA to help tenmne whether near-infrared reflectance spectroscopy (NIR) can be usedx> facilitate the sorting of recycled plastic containers. (This data set is also dismssed in Example 2 of KNN, Section 4.3.1.2.) Waste plastic containers were btained and the reflectance spectra measured in the range 1100-2500 nn. The materials represented in the data set are listed in Table 4.4.

Eventually, rapid methods based on techniques such as near-infrared reflectance spectroscopy (NIRS) are expected to replace chemical methods for routine feed analysis, but bioavailability is expected to continue to be measured in animal studies. 

The indirect methods are characterized by the need to be rapid as well as accurate and be reliable enough to be used in the cotton marketing system. These methods may be divided into the double compression airflow approach and near infrared reflectance spectroscopy (NIRS). Examples of the former (airflow) method are the Shirley Developments Fineness and Maturity Tester (FMT) [575], and the Spinlab Arealometer [576]. The NIRS approaches have been developed and discussed by Ghosh [577] and Montalvo et al. [578]. 

Bilia et al. reported the efficiency of two-dimensional homonuclear H- H correlated spectroscopy and two-dimensional reverse heteronuclear shift correlation spectroscopy in evaluating the composition of phloroglucinols, flavonols and naphthodianthrones in a dried extract of St John s wort. They successfully assigned carbon resonances for these three classes of compounds and also identified shikimic and chlorogenic acids, sucrose, lipid, polyphenols and traces of solvent (methanol) during the extraction process. This rapid technique is an alternative to HPLC, TLC or capillary GC for the analysis of St John s wort preparations. Another report utilized near-infrared reflectance spectroscopy (NIRS) for the... 

Near-infrared reflectance spectroscopy (NIRS) has been used in food industries for the determination of water, proteins, and oil content in food grains and other commodities (Williams and Norris, 2001). NIRS involves measurement of absorption spectra of a test material in the infrared region of 700 2500 nm. Compositional changes in the commodity are then correlated...

A large number of varied analytical procedures have been developed for the determination of alkaloids in tobacco. Only a few of these procedures have been described in detail. Other methods available for the analysis of alkaloids include near-infrared reflectance spectroscopy (NIRS) (McClure and Williamson 1986), lipophilic gel chromatography (Snook and Chortyk 1986), radioimmunoassay (Castro et al. 1979), mass spectrometry (Green et al. 1980), and pyrolysis-gas chromatography (Rosa 1979).

The digestibility of foods may be estimated in the laboratory (in vitro) by incubating them in rumen liquor or various chemical and enzymatic techniques. Near-infrared reflectance spectroscopy (NIRS) is now used routinely to estimate the digestibility of foods for farm advisory work.

This chapter will be about applications. It will avoid the specifics of the chemistry of near-infrared reflectance spectroscopy (NIRS), and of chemometrics. It will attempt to illustrate in one locus the variables that can affect application of NIRS to grains and seeds and their derived products. Over 50 factors associated with the grains and seeds themselves have been identified (1), any of which can interact to complicate the operation. To confuse the picture yet further is the fact that they may interact in different ways, to different degrees, and under different conditions (of temperature, etc.) and may not even interact at all. Application of NIRS to grains and seeds is complicated by the wide-ranging variance in their size, shape, color, density, composition and texture.

Total carotenoid content of com oil could be assessed at 450 nm (Wolf, 1968). In order to strengthen this information several visible absorption spectra of some edible oils are displayed in Figure 6. Near-infrared reflectance spectroscopy (NIRS) technique was used to estimate carotenoids content in maize (Brerma Berardo, 2004).
