Abstract:

Rice starch microspheres were synthesized by inverse suspension polymerization, with epichlorohydrin as the crosslinker, Span 60 as the emulsifier and soybean oil as the oil phase. Four key factors affecting the synthesis, including starch concentration, oil/water ratio, and amounts of emulsifier and cross-linker, were optimized by orthogonal test design. Results showed that their optimal levels were 25%, 3:1, 0.5 g and 2.0 ml, respectively, and under the conditions the average particle size of the starch microspheres obtained was 13.73 μm.

Key words: rice starch, microsphere, inverse suspension polymerization
