Ultrasonic modification of starch - Impact on granules porosity
1Department of Analysis and Evaluation of Food Quality, University of Life Sciences in Lublin, Skromna 8, 20-704 Lublin, Poland.
Abstract:
Rice, corn, wheat, and potato starch granules suspended in water or ethanol were treated with ultrasounds at frequency of 20kHz and power 170W for 30min. Porosity of starch was investigated in terms of specific surface area (SBET), average pore size and pore size distribution using low-temperature nitrogen adsorption method. The significant increase of SBET was noted for all the studied starches sonicated in water and for potato starch modified in ethanol. Ultrasonic treatment influenced the average diameter of mesopores (2nm
