This invention discloses a method for preparing functional almond milk beverages using a bio-enzymatic process and the resulting product. The invention removes hydrocyanic acid from almonds through a coupled cooking and soaking process, significantly reducing harmful substances. It utilizes a nonionic surfactant, imprinted lipase, to enhance enzyme activity and thus improve reaction efficiency. By controlling the rate of glycerol injection into the system, glycerol is made as compatible with oils as possible, reducing the viscosity of the reaction system and preventing glycerol from adhering to the lipase surface. The yield of diglycerides is increased by using a lipase G50 to esterify monoglycerides in the glycerol hydrolysis products, reducing the generation of harmful substances in subsequent molecular distillation. Continuous enzymatic hydrolysis of almond meal with multiple enzymes restrictively degrades macromolecules in the almond meal, releasing polyphenols and generating antioxidant peptides, thereby improving the free radical scavenging ability and stability of the almond protein paste.
