Abstract
Wheat quality characteristics play a vital role in processing and trade. Many techniques have been
introduced to evaluate wheat quality. Near Infrared (NIR) is one of the suitable techniques that have an
advantage of rapid response over other techniques. But investigations are needed to check its reliability on
determining important quality parameters. The study therefore has been designed to evaluate the efficiency
of NIR in comparison with standard techniques. Thirty samples of wheat (including 11 varieties and 19
composite samples) were analyzed. Samples were widely varied in test weight (72.4-79.9 kg/hL) and wet
gluten contents (15.4-31.5%) but showed narrow ranged moisture contents (10.8-13.3%). The NIR values
were significantly related to the referenced values for test weight, wet gluten content and moisture with the
correlation coefficients of 0.96, 0.83 and 0.73, respectively. Three consecutive measurements of test weight,
moisture and gluten contents by using NIR and referenced methods shown to have average repeatability of
0.2%, 0.3%, 2.4% and 0.1%, 0.7%, 1.5% respectively. The information is useful for maintaining the quality of
wheat intended for milling and ultimate products.
