This invention relates to the field of oil and fat synthesis technology, specifically to a method for preparing nervonic acid monoglyceride. In this invention, nervonic acid and glycerol are used as raw materials, and an esterification reaction is carried out under microwave assistance to obtain a first mixture containing nervonic acid monoglyceride, nervonic acid diglyceride, nervonic acid triglyceride, unreacted nervonic acid and glycerol, and a catalyst. Glycerol and the catalyst are removed by ethyl acetate extraction to obtain a second mixture. Subsequently, taking advantage of the temperature-sensitive nature of nervonic acid monoglyceride in edible oils, it is separated and purified to obtain nervonic acid monoglyceride. The esterification reaction under microwave assistance not only avoids the corrosion and contamination problems caused by traditional acid catalysts, but also significantly shortens the esterification reaction time, improves synthesis efficiency, and effectively inhibits the isomerization of cis-nervonic acid during the reaction, ensuring the stability of the product configuration.

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.
