“…Graded samples from each seedlot were dehulled in a Tangential Abrasive Dehulling Device (TADD, model 4E-220, Venables Machine Works Ltd., Saskatoon, Saskatchewan) with eight cups and a 128-grist abrasive surface as described by Oomah, Reichert, and Youngs (1981). Grain hardness (grams of matter removed per 100 g of whole grain) was measured by 1-min decortication of 20-g samples.…”

Effects of kernel size on grain sorghum [Sorghum bicolor (L.) Moench] quality were studied in an experiment designed to separate effects of kernel size from seedlot. The study utilized three sieve fractions of varying kernel diameter ( > 3.35, > 2.80 and > 2.36 mm) from six seedlots. Chemical composition, physical characteristics, milling characteristics, pasting properties, and cooking qualities were determined for each kernel size fraction. Large kernels lost less relative mass during 1 min of decortication, were higher in protein concentration, and lower in ash. Milling yields were higher from large kernels, and flour from large kernels had higher water absorbance, brighter white color, and larger particle size. Kernel size effects on Rapid Visco Analyzer (RVA) properties were not consistent. These results suggest that within the sorghum seedlots studied, an increase in kernel size is associated with an increase in sorghum quality as defined by the parameters measured in this study. #

Relationships Among Grain Sorghum Quality Factors

1998

Correlations among grain sorghum quality factors (proximate composition, physical properties, and water absorption properties) were evaluated. Samples of 46 commercial hybrids (24 and 22 from crop years 1993 and 1994) were analyzed for starch, protein, crude free fat, test weight, absolute density, 1,000 kernel weight, percent kernel abraded, water absorption index, initial water absorption rate, and moisture saturation point. Test weight, absolute density, and percent kernel abraded were positively correlated among themselves (r > 0.5). Protein was negatively correlated with both test weight and absolute density (r < ‐0.5), while moisture saturation point showed negative correlations with test weight, absolute density, 1,000 kernel weight, and percent kernel abraded (r < ‐0.4). Principal component factor analysis through the covariance matrix explained 95% of the total variation of quality factors among hybrids (two factors), and, through the correlation matrix, 85% of the total variation (five factors). Water absorption rate decreased with increasing starch content of grain sorghum kernels as water absorption rate increased and amount of water for saturation decreased with softening of kernels.

“…Abrasive dehulling is a front-end method of removing the outer layers of flaxseed, thereby reducing its fibre content and improving its functional and nutritional properties. A prototype Tangential Abrasive Dehulling Device (TADD) was developed (18) and further refined (19). The TADD has been used to assess hardness characteristics of sorghum (18,19), wheat, corn (20) and grain amaranth (21), the dehulling quality of legumes (cowpea, pigeon pea and mung bean) (22), seed coat breakage of field pea (23) and the removal of saponin from quinoa (19).…”
