Single Kernel Characterization of Wheat Varieties in Relation to Milling Quality

Abstract

Single kernel characterization system swiftly measures important physical characteristics of wheat grain and provides forecast for milling quality. Two wheat varieties were tested from SKCS for physical grain parameters. Wheat variety AS 2002 showed higher mean score for kernel weight (32.79mg/kernel), kernel diameter (2.77mm) and seed length (6.47mm) than Inqulab 91 (30.04mg/kernel, 2.65mm and 5.93mm repectively for kernel weight, diameter and length). Kernel density (1.61 mg/mm 3 ) and SKCS hardness index (85.65) was comparatively greater in Inqulab 91 than AS 2002 (1.54mg/mm 3 , 75.51, respectively). AS-2002 exhibited higher break (139.50g/kg), straight grade flour (681g/kg) yield and milling score (83.28) as compared to Inqulab 91 (107.50g/kg) break, (658.50g/Kg) SGF and (75.19) whereas reduction flour higher in Inqulab 91 (551g/kg) than AS 02 (541.50g/kg). Mean scores for moisture content, ash content, fat content, protein content, crude fiber and NFE ranged from 9.52 to 12.10, 0.84 to 1.14, 1.95 to 3.75%, 9.54 to 13.25%, 0.12 to 7.53% and 63.29 to 76.78% respectively in different milled fractions of both wheat varieties. Break flour yield showed significant correlation with physical grain characteristics like TKW (r=0.97), kernel diameter (r=0.99), milling score (r=0.99), seed length (r=1.00) and SKCS kernel weight (r=0.92) whereas SKCS hardness (r=-0.60) and kernel density (r=-0.54) were negatively associated with break flour. Wheat variety with greater TKW, SKCS KW, kernel diameter and seed length yield more break flour and higher milling score. However, such wheat variety had less SKCS hardness and kernel density.

Comparison of Physicochemical Properties and Metabolite Profiling Using 1H NMR Spectroscopy of Korean Wheat Malt

“…The hardness index by the SKCS was significantly lower for the AZ (27.39) than for the JK (64.29) or the KK (57.51). Based on the hardness index, the SKCS categorizes wheat kernels as hard (above 50) or soft (below 50) wheats [ 23 ]. The JK and KK can be classified as hard wheats, while the AZ is a soft wheat.…”

Physicochemical, rheological, and sensory evaluation of selected Pakistani wheat varieties

“…There is an increasing trend toward bakery products in the modern age, mostly made from wheat flour like pizza, bread, rusk, butter puff, etc. The various wheat varieties differ in protein content, α‐amylase activity, ash, moisture, and qualitative tests like the Zeleny test; their usage depends on their physicochemical composition in the products mentioned above (Iqbal et al., 2015).…”

“…From nutrition viewpoint, TD-1 and Benazir-13 had highest protein content, but these may find their potential application for bread making. Above all, AARI-11 having lower protein content acquired eminent interest and it is supported by the fact that, (Iqbal et al, 2015;Amjad et al, 2010). A wide range for wet gluten and dry gluten in wheat flour was observed from 24.68 to 36.40% and from 7.12 to 11.84%, respectively.…”
