Abstract
The invention relates to a preparation method of water melon seed oil, which belongs to the natural product extracting technique in the food and medicine field. The method of the invention comprises the processing steps: the cryodrying, the cooling and the hardback removal of water melon seeds are carried out after the sorting and classification, and then the water melon seeds which go bad, change color and have hardback are then removed, then the small granule water melon seed kernels are hardened, tempered and added with 3 percent to 12 percent of water at the temperature of 60-80 DEG C; the water melon seed kernels are cold-squeezed for two times; after two times of cold squeeze, the crude oil is filtered for two times respectively by a plate filter and a bag filter, finally, a twice press cake is powdered, the screening granularity is controlled within 50-90 meshes; after twice filtration, the crude oil is exacted by using supercritical carbon dioxide, and the unsaturated fatty acid in the residual oil of the twice press cake is purified, therefore, the finished water melon seed oil can be obtained. The water melon seed oil prepared by the method of the invention is natural and is free from pollution; in addition, the nutrient content thereof is not changed, a large great deal of unsaturated fatty acid is included and the product has high purity quotient and excellent quality.
Description
Technical field
The present invention relates to a kind of natural product extracting technique of food and medicine field, particularly a kind of preparation method of water melon seed oil.
Background technology
Contain a large amount of unrighted acids in the watermelon seed oil, its effect to human body mainly contains: the special dietary material that 1, is the control cardiovascular and cerebrovascular disease: (1) promotes cholesterol metabolic, prevents that lipid is in liver and arterial wall deposition; (2) can improve serum middle-high density lipoprotein content, certain effect be arranged reducing blood fat; (3) can reduce hematoblastic agglutinability, reduce the generation of thrombus; (4) blood vessel after inflammatory reaction takes place, can impel lipid on arterial wall calmness and cause atherosclerotic generation, and polyunsaturated fatty acid can be strengthened leukocytic effect at the damage surface of blood vessel, thereby the reduction inflammatory reaction delays the angiosclerotic process of vascular injury site; (5) polyunsaturated fatty acid can promote human defensive system's function, makes fatty acid profile in the blood towards the favourable direction of health is developed, thereby helps preventing that other from can cause and increase the weight of the generation of cardiovascular and cerebrovascular disease.2, help brain nourishing and eyesight improving: unrighted acid is an important substance of forming brain cell and cranial nerve, is the essential thing that brain cell and cranial nerve grew, kept normal operation; It can also promote the formation of neutral net, improve cardio and vascular function and blood supply in brain situation, make the self-nutrition system of brain be able to perfect, and can be to playing tangible repair because of factor atrophys such as age, dead brain cell, therefore, particularly DHA is most important to mental processes such as memory, thinkings for unrighted acid.
Summary of the invention
