The SDS sedimentation method seems unable to differentiate between eastern Canadian wheats of different remix loaf volumes especially when they have a high grain protein concentration (GPC), and is thus not suitable for use in predicting wheat strength. The sodium dodecyl sulphate (SDS) was applied to six sets of composite …
SDS-sedimentation test was conducted according to the method of Ram and Singh (2004). The levels of sulfhydryl-groups and disulfide-bonds were measured as described by Hou et al. (2017). The level of damaged starch (DS) was determined using Method 76-33.01 (AACC, 2007).
The SDS sedimentation assay was shown to be highly robust and reproducible, with ANOVA (analysis of variance) model R2 values greater than 0.98 (individual time points). …
in 1978/79 the SDS-sedimentation test and declared it to be superior to the Zeleny test in predicting baking qual- ity. More recently, Graveland et al. [7] studied the rela- tionship between the amount of SDS-insoluble gel pro- tein and the SDS-sedimentation volume and their corre- lation with bread-making quality.
Makro and mini SDS sedimentation tests had 0.96 correlation value for 90 whole-grain durum wheat samples and 0.81 for 57 whole-grain bread wheat samples. The correlation between mini SDS and wheat ...
Sodium dodecyl sulfate (SDS)-sedimentation volume (SSV) is a comprehensive indicator for indirectly testing wheat quality and one of the important tests to evaluate the gluten strength of flour and is closely related to the processing and baking quality of flour (Axford et al., 1978; Peña-Bautista, 2002; He et al., 2004).

The ability of the sodium dodecyl sulfate (SDS) sedimentation test of Axford et al. (1978) to predict quality characteristics of Canadian bread wheats has been assessed. With appropriate modifications, the test had sufficient "inherent" sensitivity to differentiate Canadian bread wheat lines, obtained from three years of Co-op tests, on the basis of …
Analyte: Sedimentation Value - SDS test. Matrix: Durum Wheat. Year of Approval: 1990. Scope: Applicable to durum wheat wholemeal. Principle: The swelling capacity of the gluten proteins of durum wheat wholemeal affects the rate of sedimentation of a meal suspension in the SDS medium. Better quality gluten gives rise to slower …

The modified macro SDS (sodium dodecyl sulfate) sedimentation test (MSDS) was performed using 3.0 g white flour, according to Williams, El-Haramein, Nakkaoul, and Rıhawi (1986, pp. 13–16). Accordingly; the whole-wheat flour (0.5 mm) was weighed into a 100 ml plastic test tube, and 50 ml of bromophenol blue solution (0.02%, …
Sedimentation tests have long been used to characterise wheat flours and meals with the aim of predicting processing and end‐product qualities. However, the use of the sodium dodecyl sulfate (SDS) sedimentation test for durum wheat (AACC International Approved Method 56–70) has not been characterised for hexaploid wheat varieties with …
