β-Glucan Assay Kit (Yeast & Mushroom) 

β-Glucan (Yeast & Mushroom) Assay Kit is suitable for the measurement and analysis of 1,3:1,6-β-glucan and α-glucan in yeast and mushroom  preparations.

New, improved procedure.

Several acid and enzyme-based methods for the hydrolysis of β-glucan were compared and the best option was the method using H2SO4. For most samples, similar β-glucan values were obtained with both the optimized HCl and H2SO4 procedures. However, in the case of certain samples, specifically Ganoderma lucidum and Poria cocus, the H2SO4 procedure resulted in significantly higher values.

Colourimetric method for the determination of Yeast and
Mushroom β-Glucan in yeast, mushroom, foodstuffs and
other materials

Principle:
                                                              (12 M H2SO4, 0°C, 2 h)
(1) 1,3:1,6-β-Glucan + 1,3-β-glucan + α-glucan + H2O →
                                                                        soluble glucan


                         (1 M H2SO4, 100°C, 2 h)
(2) Soluble glucan + H2O → D-glucose + laminarisaccharides (trace)

                  (exo-1,3-β-glucanase + β-glucosidase)
(3) Laminarisaccharides + H2O → D-glucose

                              (glucose oxidase)
(4) D-Glucose + H2O + O2 → D-gluconate + H2O2

                                                                                (peroxidase)
(5) 2H2O2 + p-hydroxybenzoic acid + 4-aminoantipyrine →
                                                                        quinoneimine + 4H2O

                       (amyloglucosidase)
(6) α-Glucan + H2O    →    D-glucose
