Abstract
Methods and solutions are disclosed for the quantification of mixed-linkage beta-glucan in plant biomass samples. Improved alkaline pretreatment, enzymatic hydrolysis, and glucose measurement parameters are provided that increase the accuracy, precision, and sensitivity of mixed-linkage beta-glucan assays.
Claims20
A method of accurately quantifying a concentration of mixed-linkage beta-glucan in a plant biomass sample, the method comprising:
- contacting the plant biomass sample with an alkaline mixture thereby generating a pretreated sample, wherein the alkaline mixture comprises a metal hydroxide at a concentration between 0.2 N and 1 N, the metal hydroxide comprising sodium hydroxide or potassium hydroxide;
- hydrolyzing the mixed-linkage beta-glucan in the pretreated sample to generate glucose;
- measuring the concentration of glucose in the pretreated sample;
- and
- transforming the measured glucose concentration to a calculated mixed-linkage beta-glucan concentration, wherein the calculated mixed-linkage beta-glucan concentration accurately quantifies the concentration of mixed-linkage beta-glucan in the plant biomass sample.
