The mucilage is a mixture of proteins, glycoproteins and polysaccharides. It is mucous and the viscosity is sensitive to heat and pH. When high concentration of salt is added, the viscosity of the mucilage is significantly suppressed. The yam mucilage shows good emulsion stability in our preliminary studies. The emulsion properties of yam mucilage will be studied including emulsion stability, particle size of the oil dispersion, protein load and rheological behaviors of the emulsion. The effects of drying on the emulsion ability will also be investigated. A model system similar to mayonnaise production will be conducted in this study.山藥多醣黏質乳化沙拉醬yamDioscoreamucilage glycansemulsionsalad dressing山藥黏質之乳化特性及其在分散油滴型產品之應用
