Study on Ultrasound Assisted Preparation of Nano Rice Starch

Abstract:

Article Preview

Nano rice starch was synthesized by ultrasonic-assisted inverse suspension polymerization, using N,N-methylenebisacrylamide (MBAA) as the cross-linker, span 80 as the emulsifier and soybean oil as the oil phase. The effects of starch concentration, oil/water ratio, ultrasonic power and ultrasonic time on adsorption of methylene blue were studied separately. The optimal conditions were obtained as followings: starch concentration 2%, ultrasonic power 320W, ultrasonic time 30min and oil-water ratio 8:1. Under above conditions, the average diameter of the prepared nanoparticles tested by particle size analyzer was 96.2 nm.
