Abstract
A supercritical extraction method of grape seed oil adopts cleaning, drying, crushing, supercritical extraction and molecular distillation, so the operating temperature is low, the heating time is short, and oil oxidation and rancidity induced by high temperature can be avoided, and the separation degree and the product yield are high; and molecular distillation also can reduce the acid value of oil, so efficient extraction, separation, no impurities and high purity of the extraction product are realized. The method has the advantages of simple operating technology, short extraction time, cost reduction and production efficiency improvement.
Description
Technical field
The present invention relates to the extracting method of raisin seed oil, especially relate to a kind of supercritical extraction method of raisin seed oil.
Background technology
Semen Vitis viniferae is a kind of by product of wine brewing, not only pollute the environment if be not used, and be that the one of resource is wasted, because the grease also containing 13% ~ 15% in Semen Vitis viniferae, in raisin seed oil, unsaturated fatty acid content reaches 90%, wherein linoleic acid content is up to 80%, can compare favourably with safflower oil.Linolic acid is the important source material of synthesis four diluted acid, and has and prevent the effect such as thrombosis, vasodilation.In addition, raisin seed oil also containing more rich physiology oil components, makes it have some physiological functions being different from oil with common edible.As hypotensive, removing cholesterol, nourishing brain cell etc.Now, to be used as the specific nutrition health-care oil of baby, the elderly, working aloft personnel, hyperpietic.In addition process good raisin seed oil and also can be used as makeup, the base-material of medicine.The Semen Vitis viniferae deep processing product of listing are little, this greatly reduces the economic worth of China's Semen Vitis viniferae.
A kind of kiwifruit nut oil and extracting method thereof disclosed in Chinese patent Authorization Notice No. CN1483795, adopt CO_2 supercritical technology, obtained essential oil of low quality, and complex process, extraction time is long, and production cost is high, and yield is low.
In view of the foregoing, a kind of supercritical extraction method of raisin seed oil is now developed.
