We recommend that the smallest differentiating absorbance ΔA should be at least 0.04 with GOPOD Reaction. This is the equivalent of approximately 0.35% of β-glucan in powder samples, when the streamlined method is followed as described in the data booklet. If the procedure (B) for cooked, toasted or extruded cereal products is used the limit of detection is 0.1%.
