By further comparing the materials used, the Laywoo-D3 has an extremely good adhesion and no vitreousness occurs when printing, while an adequate substrate for better adhesion is required for the PLA material.
The system was originally developed to measure wheat quality characteristics, such as protein, hardness, vitreousness, fungal damage, toxin levels, and sprout damage from the NIR spectrum.
High protein concentration, along with a translucent, amber-yellow color, are referred to as kernel vitreousness (Abaye et al., 1997).
Proximate and physiochemical analyses (including PSI and vitreousness) were conducted using Near Infrared Reflectance spectroscopy which was carried out using a Foss 6500 NIR spectrophotometer (FOSS NIRSystems, Inc, Maryland, USA).
Notwithstanding the inherent problems associated with using a hard wheat to produce a bright noodle product and the existence of a environment, which favors the production of spring wheat with high grain protein, ash content, and kernel vitreousness, we suggest a breeder for the U.S.
His current projects include using NIRS to detect wheat color class, durum vitreousness, scab and vomitoxin.
(2001) suggested that environmentally induced variations in grain protein content, hardness, vitreousness, and kernel size and shape might all contribute to variation in visual grain color.
The mechanical resistance of endosperm is often expressed in terms of endosperm vitreousness. However, several authors have shown the intrinsic semolina value of the endosperm to be affected in clearly different ways, depending on the degree of starchiness of the endosperm (caused by yellow berry) (Matveef, 1963, Dexter and Matsuo, 1981).
