The method describes how to determine the β-glucans in wort or Congress wort by means of a colorimetric method.
Applicable for all (laboratory) worts
The colorimetric method may be used for the determination of high molecular weight β-glucan in wort; it is based on the photometric evaluation of a β-glucan color complex. The soluble β-glucan from barley reacts with a buffered solution, forming a color complex within 30 minutes. The absorbance of the β-glucan color complex is measured at 550 nm.
