Description
Technical field
The present invention relates to vegetable oil preparing technical field, it is more particularly related to which a kind of be rich in high content insatiable hunger
With the production method of the vegetable oil of aliphatic acid.
Background technology
With the rapid development of economy, living standards of the people are increased substantially, nutrition and peace are more focused in the selection to food
Entirely.In terms of grease, because unrighted acid has the healthcare functions such as regulation blood fat, cleaning thrombus, so rich in unsaturation
The grease of aliphatic acid is increasingly liked by the people.
(not double bond containing aliphatic acid turns into saturated fatty acid, all animal oil to aliphatic acid in addition to saturated fatty acid
Except being all saturated fatty acid, fish oil) it is exactly unrighted acid.Unrighted acid is one kind fat for constituting body fat
Acid, aliphatic acid needed by human.Unrighted acid is divided into monounsaturated fatty acids and many insatiable hungers according to the difference of double bond number
With two kinds of aliphatic acid.In food fat, monounsaturated fatty acids has oleic acid, and polyunsaturated fatty acid has linoleic acid, leukotrienes, flower
Raw tetraenoic acid etc..Human body can not synthesize linoleic acid plus linolenic acid, it is necessary to be supplemented from meals.Different from saturated fat, many insatiable hungers
It is in a liquid state at room temperature state with fat, and is still liquid when refrigeration or freezing.Monounsaturated fatty acid, such as
Found in olive oil, liquid, but will be hardened when refrigeration at room temperature.
Safflower seed oil and grape-kernel oil in such as vegetable oil contain abundant unrighted acid, its be mainly oleic acid and
