复乳(Multiple Emulsion)是由普通单乳进一步乳化而成的复杂乳剂体系,常见的有W/O/W 型与O/W/O 型等几类。前者由油包水型(W/O)初乳经再乳化而分散于水相所得;后者由水包油型(O/W)初乳分散在油相中制得。近年来,复乳在医药、生化和分离科学中获得日益广泛的应用。例如将激素类、酶类等药物制成复乳,可避免在肠胃道中失活, Multiple Emulsion is a complex emulsion system further emulsified from ordinary single milk, there are several types of W / O / W and O / W / O common. The former is obtained by re-emulsifying and dispersing the water-in-oil (W / O) colostrum in the aqueous phase; the latter is obtained by dispersing the oil-in-water (O / W) colostrum in the oil phase. In recent years, the complex milk in medicine, biochemistry and separation science has been increasingly widely used. For example, hormones, enzymes and other drugs made of complex milk, to avoid inactivation in the gastrointestinal tract,
