Technical Abstract: Dry beans are a rich source of basic nutrients. However, oligosaccharides including raffinose, stachyose and verbascose, in beans are present at levels that cause gastro-intestinal discomfort and limit their consumption. The objective of the research was to determine the optimum conditions that reduce the concentration of oligosaccharides in black and pinto bean flours by enzymatic treatment. Oligosaccharide concentrations were determined by HPLC coupled with refractive index detection. Flours treated with Beano® in tablet or liquid form, at 55 degrees Celsius and reduced pH, resulted in a reduction of 54-76 and 61-85 percent of total oligosaccharides, respectively. Production of nutritious, value-added bean products with low concentration of oligosaccharides will improve dry beans' consumer acceptability.
