Method for extracting macadamia nut oil through enzymatic pretreatment assisted hydraulic squeezing

The invention relates to a method for extracting macadamia nut oil by enzymatic pretreatment assisted hydraulic squeezing, which specifically comprises the following steps of: firstly, removing green peels of harvested fresh macadamia nuts to obtain macadamia nut kernels, cleaning, drying, and removing impurities by an air screen to obtain the macadamia nut kernels; then crushing to obtain nutlet grains; then adding a pectinase solution and a pH buffer solution A, and carrying out enzymolysis in a constant temperature box at 50-60 DEG C for 1-2 hours; after the enzymolysis is completed, fishing out the nutlet grains, and draining off the nutlet grains; adding a cellulase solution and a pH buffer solution B, and carrying out enzymolysis in a constant temperature box at 50-55 DEG C for 1-2 hours; fishing out the nutlet grains, and drying with hot air until the water content is below 9%; and finally, putting the kernels subjected to secondary enzymolysis into a squeezer, and squeezing to obtain macadamia nut cru
