ABSTRACT: Mushrooms are recognized as sources of β-glucan. The aim of this study was to purify β-glucan from oyster mushrooms (Pleurotus pulmonarius) by alkaline extraction. The extracted β-glucan was added to a cracker recipe and the sensory, physical and estimated glycemic index of the final product were evaluated. Optimum extraction parameters were determined to be 80˚C, 90 minutes and 30% KOH. The β-glucan crackers had a glycemic index ranging from 88.07 to 67.32, while glucose had a glycemic index of 100. Based on the sensory study, it can be concluded that crackers enriched with β-glucan and possessing functional qualities may meet consumer expectations.
