- Material disintegration is the primary step in beta-glucan determination in cereal grains. This study investigated the effect of disintegration approach on beta-glucan content, determined by an enzymatic method in mature kernels of barley and oat. Milling with a coffee grinder was found to be relevant only for pre-disintegration and homogenization of the grain (4.6% and 3.2% beta-glucan content was found in barley and oats, respectively). Ball milling appeared to be the most efficient approach for reducing material particle size, but resulted in samples with underestimated beta-glucan content (4.6% and 3.3% in barley and oats, respectively). Grinding with mortar and pestle in liquid nitrogen and repeated centrifugal milling were found to be the optimal disintegration methods for barley kernels (5.2% and 4.7-4.8% beta-glucan content, respectively). Grinding with mortar and pestle (either in dry state or in liquid nitrogen) and single centrifugal milling were the optimal disintegration methods for oat kernels (3.6-3.9% and 3.3-3.4% beta-glucan content, respectively).
