Lipase　is　widely　used　in　the　food　industry,　but　its　catalytic　efficiency　is　limited　by　the　insufficient　enzyme-substrate　contact.　To　address　this　issue,　chitosan-zein　complex　particles　immobilized　lipase　(CZPs-lipase)　and　the　corresponding　Pickering　emulsion　catalytic　system　(PEC)　were　fabricated.　The　results　showed　that　the　incorporation　of　zein　increased　the　three-phase　contact　angle　of　the　particles　and　decreased　the　particle　size,　facilitating　lipase　immobilization.　However,　the　reduced　zeta-potential　of　the　particles　was　unfavorable　for　the　lipase　immobilization　by　electrostatic　adsorption.　As　a　compromise,　the　maximum　immobilized　lipase　activity　was　obtained　at　a　chitosan:zein　mass　ratio　of　1:2　(CZPs(1:2)-lipase).　In　addition,　the　PEC　stabilized　by　CZPs-lipase　had　a　significantly　(P　＜　0.05)　smaller　particle　size　than　that　stabilized　by　chitosan-lipase　particles.　Consequently,　after　120　min　of　reaction,　the　hydrolysis　rate　of　p-nitrophenol　palmitate　in　the　PEC　stabilized　by　CZPs(1:2)-lipase　was　1.66　and　3.67　times　that　of　the　free　lipase　emulsion　and　the　free　lipase　biphasic　catalytic　system,　respectively.　Meanwhile,　after　180　min　of　reaction,　the　hydrolysis　rate　of　corn　oil　and　soybean　oil　in　the　PEC　reached　75.68　+/-　1.85　%　and　96.27　+/-　2.26　%,　respectively,　significantly　(P　＜　0.05)　higher　than　that　in　the　free　lipase　emulsion.　After　five　cycles,　the　relative　hydrolysis　rate　remained　at　approximately　85　%.　This　efficient　PEC　has　considerable　potential　for　applications　in　the　food　industry.
