Process method for removing benzopyrene in grease

The invention relates to a process method for removing benzopyrene in grease. The grease is eluted by adopting DNA (deoxyribonucleic acid) aqueous solution; the benzopyrene in the grease is intercalated with DNA; DNA is dissolved in water, so that the benzopyrene intercalated with the DNA is brought into the water; oil cannot be dissolved in water, so that after standing, separation is carried out to obtain the grease of which the benzopyrene is removed. Currently, removal on the benzopyrene in the grease mainly adopts an adsorption method, such method can also adsorb aroma components in the grease when adsorbing the benzopyrene, and resolving and processing after adsorption are very difficult. According to the process method disclosed by the invention, the adsorption method for removing the benzopyrene is improved; by improvement, grease loss is effectively reduced, a removal effect is improved, and post-processing difficulty is reduced; meanwhile, the process method has the advantages of convenience for use
