普鲁兰多糖的吸湿、保湿性及其黏度稳定性
Viscosity Stability and Moisturizing Performance of Pullulan
摘要
Abstract
By comparing hyaluronic acid and glycerin,the moisture absorbing and retaining capacities of pullulan were investigated.Kinetic analysis of moisture absorption process of pullulan was carried out.In addition,the moisture retaining capacity of pullulan with different viscosity and the effects of temperature,pH and Na+concentration on the viscosity stabil-ity of pullulan were examined.Under atmospheric condition of RH 81%,,the moisture absorbing and retaining capacities of pullulan were similar to those of hyaluronic acid,and its moisture absorption process meets the mode of second-order ad-sorption kinetic equation with correlation coefficient higher than 0.99.The optimal concentration for moisture retention was 1,mg/mL(42.7,mPa·s).The viscosity of pullulan has good stability to temperature,pH and ion concentration.This research has provided a theoretical basis for using pullulan as a water-absorbing agent,thickener and stabilizer in food,as well as a moisturizer factor in cosmetics.关键词
