Ganoderma lingzhi spore oil is a kind of health oil with pharmacological activities. Encapsulation of G. lingzhi spore oil by spray‐drying and freeze‐drying methods using soy isolated protein and malt dextrin as wall material for improving spore oil stability was carried out. Single factor experiment was employed to obtain the optimal conditions. The results showed that the optimal technology for encapsulation was: soy isolated protein and malt dextrin in the ratio of 1:1, solid content of 20%, homogeneous pressure of 30MPa, and core and wall materials in the mass ratio of 4:1. The mobility and solubility of microcapsules prepared by spray‐drying and freeze‐drying were good and there were no significant difference. However, structures of two kinds of microcapsules were different. Spray‐drying microcapsules were spherical with closely‐knited surface, no crack but with some dents. Encapsulation efficiency of spray‐drying microcapsules was higher, reaching 90.84%. Freeze‐drying microcapsules were porous and loose, with flake‐like structure.Therefore, spray‐drying is a better method to prepare G. lucidum spore oil microcapsules.
