Abstract
The invention relates to a supercritical extraction method of pumpkin seed oil, which comprises the following steps: cleaning, drying, pulverizing, supercritical extraction and molecular distillation. The method has the advantages of low operating temperature, short heating time, higher separation degree and higher product yield, and can prevent oil from oxidation and rancidity due to high temperature. The molecular distillation can lower the acid number of the oil. The method achieves the goals of efficient extraction and separation, no impurity and high extraction product purity. The method has the characteristics of simple operating technique and short extraction time, lowers the cost and enhances the production efficiency.
Description
Technical field
The present invention relates to the extracting method of Semen Cucurbitae oil, especially a kind of supercritical extraction method of Semen Cucurbitae oil.
Background technology
Pumpkin has another name called pumpkin, meal melon, Chinese squash etc., belongs to Curcurbitaceae annual herb plant.The nutritive ingredients such as the nutritive value of pumpkin is very high, is rich in amino acid, carotene, VB, VC, N.F,USP MANNITOL, pumpkin element, have promote insulin secretion, hypoglycemic, reduce the dietary function of cholesterol.In recent years.Along with people's deepening continuously to pumpkin nutrient value recognization, cultivated area and the consumption of pumpkin sharply expand, and create a large amount of Semen Cucurbitae, and Semen Cucurbitae are rich in grease, just the very good material of development functionality edible oil.
Semen Cucurbitae is the seed of cucurbitaceous plant pumpkin, and in flat ellipse, seed coat is thicker, removing seed coat, the endosperm that visible green is poor, inside has two pieces of yellow plump midnights.Pumpkin seed oil length, up to about 50%, also contains rich in protein, vitamin A in addition.Main component in fatty oil is linolic acid, oleic acid, the glyceride such as stearic acid, and Semen Cucurbitae oil, as a kind of quality plant oil, is particularly suitable for hypertension, diabetes patient.If extract grease by conventional press method, there is processed oil color and luster comparatively dark, protein contained in grouts after squeezing can variability, and the shortcoming that in grouts, residua content is high, if with the lixiviate of hexane kind solvent, then have the more unmanageable shortcoming of the problem of solvent residual in product.
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 Semen Cucurbitae oil is now developed.
Summary of the invention
The object of the invention is, in order to overcome deficiency of the prior art, a kind of supercritical extraction method of Semen Cucurbitae oil to be provided, to achieve efficient extraction, separation, inclusion-free, the object that extracted products purity is high, operating procedure is simple, and extraction time is short, reduce cost, improve production efficiency.
The present invention to achieve these goals, adopts following technical scheme: a kind of supercritical extraction method of Semen Cucurbitae oil:
