Abstract: Acidproof microencapsulated oil powder was prepared by spray-drying technique on the basis of a screening and testing research on the formula of emulsifier, and its partial performances were tested and evaluated. The results showed that in the medium at pH 2, the emulsion stability of reverted emulsion of the prepared microencapsulated oil powder is good, no layer phenomenon and phenomenon of particle hanging on wall, and the embedding rate reaches 97.5%.

Key words: oil power, emulsifiers, particle size, acid resistance
