This may be formed of cellulose acetate products, i.e., wood pulp. The cellulose acetate products can be heat sealed to offer gas barrier properties and can be tailored to achieve a range of moisture barrier properties. Alternatively, such products made from whole grain cereals, or zein, a corn gluten product.

Since the 1970s, NIR spectroscopy has provided the means to test wheat at delivery to handlers, merchants, or direct to the mill. For ground wheat, protein may be determined with three or four fixed filters 2180, 2100 (1940 required for corrected moisture basis), and either 1680 or 2230 nm. In countries with wheat grading systems, such as Australia, Canada, and the US, segregation is carried out on the basis of load-by-load NIR testing of growers deliveries at country silos. Nowadays, this is almost exclusively by whole grain instruments, the most popular of which is the FOSS Infratec. This type of instrument is calibrated with tens of thousands of samples and development of a model based on artificial neural networks (8, 9). 

Moisture is routinely measured concurrently with protein. Measurement may be made on ground wheat with two or three fixed filters (1940, 2230, and/or 2310 nm) or on whole grain as described above. Under ideal laboratory conditions, the standard deviation of differences between NIR and reference moisture values should be 0.25% or better. It is essential to record the NIR spectral data and determine the oven moisture contents of the calibration samples as close as possible in time, ideally on the same day. 

A moisture meter measuring the dc conductance in a circuit was developed from the Wheatstone bridge [83]. Because the electrical properties of whole grain are preferentially affected by the moisture content of the surface layers, the kernel is ground before the test. In a test cell, the meal is compressed against... 

The starch plasticization is obtained by gelatinization of the grains in low moisture conditions leading to the melting of the starch grains. This is the key phenomenon in the transformation of the whole corn plant. The plasticized starch forms a continuous matrix in which the defibrated fibers are embedded, as showed schematically in Figure 5.22.
