摘　　要：起云剂又名增浊剂,是一种乳化稳定剂,其作用是在溶液中起到乳化、增稠、稳定作用,使不易相融的水油溶液能够形成混合均匀的胶状分散体,可以防止出现沉淀,并能增加口感。由于海藻酸丙二醇酯含有亲水性及亲油性的基团,添加在饮料及食品中可以起到乳化和增稠的作用,是一种天然的起云剂,在运动饮料、各种果汁饮料、益生菌、乳酸菌饮料、果冻等食品中有很好的应用价值。Clouding agent, also called turbidifying agent, is a type of emulsifying and thickening agent. It can emulsify, thicken and stabilize solution, and form a uniform colloid dispersion for solutions containing oil and water, thereby preventing the formation of precipitate and improving taste. Because propylene glycol alginate （PGA） contains both hydrophilic and hydrophobic groups in its structure, it can function as both emulsifying and thickening agents when added into beverage products, acting as a natural clouding agent. PGA can be widely used in sports drinks, juices, probiotics, lactobacillus, gelly food and many other types of foods and drinks.
