Abstract

The invention relates to a method for extraction of Cornus walteri seed oil by combination of superhigh pressure treatment and subcritical double solvent extraction. The method comprises 1, crushing Cornus walteri seeds, drying the crushed Cornus walteri seeds and carrying out pretreatment at a temperature of 30-40 DEG C under pressure of 300-350 MPa, 2, carrying out extraction on the Cornus walteri seeds pretreated by the step 1 in a subcritical fluid at a temperature of 120-180 DEG C under pressure of 3-7MPa to obtain extract, and 3, carrying out cooling and demulsification on the extract obtained by the step 2, carrying out standing layering, and taking a liquid in the upper layer, wherein the liquid in the upper layer is Cornus walteri seed oil. The superhigh pressure pretreatment is carried out prior to the subcritical fluid extraction and is carried out at a temperature of 30-40 DEG C under pressure of 300-350MPa for 10-15min so that lipoxidase and polyphenol oxidase in Cornus walteri seeds are passivated and even loses activity, microbes on Cornus walteri seeds are killed and a color, a fragrance, a taste, nutrients such as vitamins and local flavor substances of the food are not influenced and a recovery rate is obviously improved.

Description

technical field [0001] The invention relates to a method for extracting fenugreek seed oil, in particular to a method for extracting fenugreek seed oil with ultra-high pressure combined with subcritical dual solvents, and belongs to the technical field of oil plant extraction. Background technique [0002] As a kind of woody oil with an oil content of 35-38%, its tree species are resistant to salt and alkali, drought, high survival rate of seedlings, and the full fruit period can reach 60 to 70 years. It can be used as edible oil or biodiesel. To a large extent, the pressure on my country's oil market has been eased. There are many types of fatty acids in hairy bean oil, mainly including linoleic acid, oleic acid, palmitoleic acid, palmitic acid, stearic acid, etc. Among them, unsaturated fatty acids are rich in content, accounting for more than 70% of the total fatty acids. In recent years, my country's edible oil market is mainly occupied by herbal oils such as soybeans, r...
