淀粉乳液形成过程主要影响因素的耗散粒子动力学模拟与实验
Dissipative Particle Dynamics Simulation and Experiments of Main Influence Factors of Conformation of Starch Emulsion
摘要
Abstract
With cyclohexane as oil phase, amylose as aqueous phase, meanwhile Span60 and Tween60 as emulsifiers influence factors of conformation of starch emulsion were investigated by dissipative particle dyna mics ( DPD) simulation. It is shown from DPD simulations that the system becomes equilibrated after 6000-step simulation, the size of micro particle decreases firstly and then increases with the increase of the content of emulsifiers, but increases with the increase of starch content and the decrease of the content of cyclohexane. The parameters of forming the stable starch emulsion system are 7 < oil-water ratio =≤20 and 9%< content of emulsifier ≤ 18 % . The results show that the sizes of the microspheres decrease with the increase of the content of emulsifier( from 11 % to 15% ) , but increase when content of emulsifier higher than 15% . The experimental results are consistent with the simulation results.关键词
