Beta-amylolysis

Figure 6.5 Gel permeation chromatogram of isoamylase-treated potato amylose on Toyopearl HW-75F. Potato amylose (50 mg in 5 ml ) was incubated at 45°C with 5.5 U of Pseudomonas isoamylase in 20 mM acetate buffer (pH 3.5) for 2.5 h. An aliquot (1 ml.) was applied to the column — and , carbohydrate concentration and beta-amylolysis limit, respectively, of the isoamylase-treated amylose ., carbohydrate...

The iodine affinities, blue values, max, beta-amylolysis limits and branch chain length distributions are similar for the starch samples harvested at different stages (7 to 30 days DAF) of development of waxy rice grains,331 japonica rice328 and indica rice.332 The gelatinization temperature of maize starch increases from 12 to 24 DAF, but is reduced at 36 DAF.333...
