Abstract

The invention discloses a low-temperature cold pressing process of flaxseed oil. The process comprises the following steps: (1) selecting and airing flax seeds, wherein plump flax seeds with no mildewand no insect erosion and with normal color and smell are selected; (2) carrying out screening by air separation or magnetic separation: carrying out air separation or magnetic separation on the selected flax seeds through a fan or a magnetic separator, removing soil and other impurities, and reducing the impurity content to 1% or below; and (3) cleaning and rinsing the flax seeds, performing reduced pressure drying at a temperature less than 65 DEG C to enable the water content in a range of 3%-5%, and performing irradiation under ultraviolet light for 15-30 minutes. The process provided bythe invention improves the purity and transparency of the flaxseed oil, ensures the edible safety, and removes excess pigment, oxides, trace metals, polycyclic aromatic hydrocarbons and pesticide residues in the oil under a vacuum condition, the product quality reaches a high level, and moreover the flaxseed oil can be directly eaten as food or be added into other products as nutrient enrichment for a certain health-care effect.

Description

technical field [0001] The invention specifically relates to a low-temperature cold pressing process of linseed oil, which belongs to the technical field of food. Background technique [0002] Flaxseed is pressed to produce linseed oil, which has attracted much attention recently because it is rich in a-linolenic acid, a nutrient required by the human body. a-linolenic acid, also known as "brain gold" and "vegetable fish oil", is an essential fatty acid for the human body. It cannot be naturally produced in the human body, but can only be taken from the outside. It has the functions of dissolving cholesterol, lowering blood fat, lowering blood acid, and lowering blood sugar. , lower blood pressure and other effects; can prevent cardiovascular disease, two-way regulation of blood pressure, blood lipids, brain, anti-aging and promote the normal development of the human body. The traditional extraction method of linseed oil is: linseed-selection-steaming-pressing-semi-refined-...
