The invention discloses compound lipase and application thereof. The compound lipase comprises Novozym435 lipase, candida rugosa lipase and wild DF15 lipase according to the mass ratio of (4-6):(5-8):(2-3). The Novozym435 lipase, the candida rugosa lipase and the wild DF15 lipase are mixed, so that the enzymolysis time is shortened, the enzymolysis efficiency and the enzymolysis degree are improved, and furthermore, the flavor components of zymolyte are enriched. Butter zymolyte prepared from the compound lipase is more mellow and richer in fragrance, the sour and greasy smell is proper, the milk fragrance and the fat fragrance are extremely harmonized, and the compound lipase has an obvious effect on milk type essences such as flavoring butter essences.
