Abstract

The invention discloses an aqueous enzymatic method for extracting zanthoxylum seed oil. The method comprises the following steps: drying and smashing zanthoxylum seeds, performing enzymolysis, filtering, performing centrifugal separation, performing demulsification in combination with an electrolyte and membrane separation, and then merging an oil fluid to obtain a finished zanthoxylum seed oil product. The zanthoxylum seed oil prepared by adopting the method is yellowish-brown, clear and transparent, and has zanthoxylum seed fragrance; and the extraction rate is 90% to 93%. The adopted method meets the safe and green requirements of oil and fat production, the adopted enzymatic method damages plant cell walls, the reaction condition is mild, the energy consumption is low, the extraction rate is high, the electrolyte is adopted to be combined with membrane separation for demulsification, the operation is simple, the demulsification efficiency is high, the produced zanthoxylum seed oil is high in quality, the oil and fat extraction rate is high, the pollution is little, and the method is beneficial for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of bio-oil processing, and specifically relates to a method for extracting and refining paprika oil, in particular to a method for preparing paprika oil by combining aqueous enzymatic extraction and electrolyte and membrane separation with demulsification technology. Background technique [0002] Zanthoxylum bungeanum has a wide range of planting in my country, especially in Shandong, Sichuan, Shaanxi and other regions. The output of Zanthoxylum bungeanum is large and the quality is good. Wastes are discarded, which not only pollutes the environment, but also wastes resources. Studies have shown that peppers mainly contain fatty acids, volatile oils, amino acids, trace elements, etc. The fatty acids are mainly α-linolenic acid, linoleic acid, palmitic acid, palmitoleic acid, oleic acid and other components, and the content of α-linolenic acid Up to 30% or more. α-linolenic acid (α-inolenic acid), as an esse...
