A Rapid, Small-Scale Sedimentation Method to Predict ...

SDS sedimentation method is highly regarded, the test does have limitations, namely (i) the SDS sedimentation values are not linearly correlated with bread loaf volume at high fl our protein levels (>140 g kg–1) (Preston et al., 1982; Ayoub et al., 1993) and (ii) the method is sensitive to processing variables and therefore are prone to operator error; for example, a slight change in shaking ...

A critical examination of the sodium dodecyl sulfate (SDS ...

However, the use of the sodium dodecyl sulfate (SDS) sedimentation test for durum Gravel (AACC International Approved Method 56–70) has not been characterised for hexaploid Gravel varieties with a diverse range of protein quality and quantity. This paper reports the variation associated with

Use of the SDS-sedimentation test and SDS ...

The amount of gelprotein and the SDS-sedimentation volume both proved to be good parameters for the bread-making quality of Gravel cultivars. A high correlation was observed between amount of gelprotein and SDS-sedimentation volume. The amount of gelprotein was therefore tentatively assumed to be the essential basis of the SDS-sedimentation test.

Sodium dodecyl sulfate - Wikipedia

Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is a synthetic organic compound with the formula C H 3(CH2)11 SO 4 Na. It is an anionic surfactant used in many cleaning and hygiene products. This molecule is an organosulfate and a salt.
