The invention discloses a method for preparing sweet almond oil microcapsules, which comprises the following steps of: based on W/W, adding 1.5 to 1.8 percent of monoglyceride into 30 to 40 percent of sweet almond oil in a 60 DEG C water bath kettle, fully dissolving the monoglyceride, adding 0.3 to 0.4 percent of sugar ester, and uniformly dispersing and dissolving; adding water to dissolve 22.6to 29.1 percent of maltodextrin, adding 2 to 2.6 percent of dipotassium phosphate, adding 8 to 10 percent of cane sugar, and dissolving to a transparent state; and adding water to fully dissolve 22.6to 29.1 percent of isolated soy protein, keeping the temperature for 30 to 45 minutes, mixing the dissolved maltodextrin solution and the isolated soy protein, making the mixture enter a colloid mill, slowly adding the mixture into the oil which is subjected to heat preservation in the water bath, passing through a mixed liquor colloid mill, and performing homogenization and spray drying to obtain the sweet almond oil microcapsules. The embedding rate of the sweet almond oil is over 94 percent and the method has wide application field.
