香菇多糖基凝胶面膜的制备及其性能研究

Study on preparation and performance of lentinan-basedgel facial mask

以香菇多糖、凝胶基质为原料,制备了食用菌补水面膜,通过正交试验得出面膜较优配方,并研究其感官、质构、LF-NMR、流变、抗氧化和皮肤水分测试.结果表明:筛选的羧甲基纤维素钠(CMC-Na)为最佳凝胶基质;单因素和正交试验得出香菇复合多糖凝胶面膜的最优配方包括:CMC-Na 3.3 g,香菇多糖1 g,甘油4 mL,山梨醇2 g,山梨酸钾1 g, VC 1 g,去离子水100 mL.香菇多糖凝胶面膜的弹性和对照组无显著性差异,粘聚性以及凝胶强度高于对照组,其凝胶强度为18.142 g;香菇多糖凝胶面膜与对照面膜中均含有自由水;流变分析表明香菇多糖面膜凝胶的粘性模量高于对照组;香菇多糖面膜凝胶的抗氧化能力高于对照组,并且DPPH自由基清除率随着面膜质量浓度增大而增大,最佳浓度为5 mg/mL;保湿率高于芦荟胶面膜,但略低于睡眠面膜,在2 h时保湿率最佳值是99.46%;面部皮肤水分含量结果表明,香菇多糖面膜凝胶对不同的人都有显著的保湿效果,试用者的面部皮肤水分含量从28.314%提高至33.472%.香菇多糖凝胶面膜的开发为最大限度地发挥香菇多糖的价值提供了一个全新的思路.

In this paper,an edible mushroom hydration mask was prepared with mushroom polysaccharide and gel matrix as raw materials,and the better formulation of the mask was prepared through orthogonal experiments,and studied its sensory,textural composition,LF-NMR,rheology,antioxidant and skin moisture tests.Results reveal that CMC-Na is the optimal gel matrix.The ideal formulation,determined through single-factor and orthogonal tests,includes:CMC-Na 3.3 g,lentinan 1 g,glycerin 4 mL,sorbitol 2 g,potassium sorbate 1 g,VC 1 g,deionized water 100 mL,the lentinan facial mask gel demonstrates higher cohesiveness and gel strength without significant differences in elasticity,with a gel strength of 18.142 g.Both lentinan and control masks exhibit free water.Rheological analysis reveals slightly higher viscous modulus in the lentinan gel.The lentinan facial mask gel outperforms the control in antioxidant capacity and the DPPH free radical scavenging rate increased with the increase of mask mass concentration,with the optimal concentration of 5 mg/mL;and exhibits better moisturizing than aloe gel facial mask,though slightly less than sleeping facial mask,with the optimal value of moisturizing rate of 99.46%at 2 h.Skin moisture content analysis demonstrates lentinan′s substantial moisturizing effects across diverse individuals,and the moisture content of facial skin of the trial participants increased from 28.314%to 33.472%.The development of lentinan gel facial mask introduces a fresh perspective for maximizing lentinan′s value.
