Description
Technical field
The present invention relates to the Vegetable oil lipoprotein production technical field, specially refer to a kind of supercritical CO that utilizes
2Abstraction technique extracts the method for wax gourd seed oil.
Background technology
The wax gourd seed is the kind benevolence of Curcurbitaceae Benincasa wax gourd, since ancient times, is usually used in whitening and skin-protecting and phlegm heat cough, lung carbuncle, and acute appendicitis, gonorrhoea, under the band, beriberi, oedema, treatment of diseases such as stranguria.Its pharmaceutical use sees Shennong's Herbal the earliest: " make us the good color in happy pool, beneficial gas is not hungry.Obey for a long time, it is anti-old to make light of one's life by commiting suicide, the sliding clean as jade of the face that makes us "; Thereafter, the classics of TCM such as " cuisine canon ", Compendium of Material Medica have also been put down in writing its effect such as light spot of losing weight.The contained main lipid acid of wax gourd seed is linolic acid, oleic acid, stearic acid and palmitinic acid, also contains lipoid, phytosterin compound and triterpene compound etc.
Lipid extracting method commonly used is mainly milling process, solvent method and aqua method.The characteristics of milling process are that required equipment is few, and technology is simple, and adaptability is strong, and is solvent-free residual.But its oil yield is low, subsequent disposal is complicated, and high temperature steams the thermo-sensitivity composition of frying in the easy destruction oil plant.The characteristics of solvent method are to realize serialization, automatization easily, and labour intensity is low, production efficiency is high, and oil yield is higher relatively, but have dissolvent residual, oil complicated component, purity lower.The characteristics of aqua method are can extract fuel-displaced and protein simultaneously, but can produce a large amount of milk sap in the oily process of system, badly influence free oil separating, and yield is lower, and the purity of oil is lower.Zhou Qing etc. (Zhou Qing, Jiang Hao, high clouds etc., wax gourd seed water extract Study on antioxidation, trace element and health research, 2010,27 (5), 22-23) once adopted aqua method to carry out the extraction of wax gourd seed, its yield only is 17%.
Summary of the invention
The present invention is in order to overcome the deficiency of conventional grease extractive technique, a kind of environmental friendliness to be provided, and extraction and separation process is easy, the extracting method of free of contamination wax gourd seed oil.
Following technical proposals of the present invention realizes:
(1) the wax gourd seed is carried out peeling, drying, pulverize, the 10-40 order sieves;
(2) the wax gourd powder of seeds behind the crushing screening is adopted supercritical CO
2Extraction process extracts, and wherein, the consumption of entrainment agent dehydrated alcohol is 0-5%V/VCO
2(be liquid anhydrous ethanol and liquefaction CO
2Volume ratio), extracting pressure is 25-40MPa, supercritical CO
2The temperature of extraction is 35-55 ℃, extraction time 30-90min.
The drying temperature of wax gourd seed is a room temperature after the middle peeling of step (1), and be 2 weeks time of drying.
Supercritical CO
2In the extraction process, comparatively preferred condition is as follows: the consumption of entrainment agent dehydrated alcohol is 3%V/VCO
2, the granularity of wax gourd powder of seeds is 40 orders, extracting pressure is 30MPa, supercritical CO
2The temperature of extraction is 40 ℃, extraction time 60min.
The present invention has following technique effect:
The extracting method of wax gourd seed oil of the present invention adopts supercritical CO
2Extraction process, its principle are to utilize the supercritical flow volume density to change along with the variation of its pressure and temperature, and then influence its dissolving power, reach the purpose of dissolving extract.Therefore, adopt supercritical CO
2Abstraction technique environmental friendliness, extraction and separation process are easy, no solvent residue, product purity is higher, quality is better, with short production cycle, and, make extraction yield up to 49.59g/100g by to the determining of processing condition such as temperature, pressure in the leaching process.
