Abstract
The invention is a method for extracting safflower seed oil by supercritical CO2, putting 0.3-0.5mm-sized crushed safflower seeds in the extracting cylinder of a supercritical extractor, and using supercritical CO2 as extractant to make extraction at 20-28MPa and 35-60DEG C; separating after extraction, where primary separation pressure and temperature are 9-14MPa and 35-50DEG C, respectively, and the corresponding product is safflower seed oil; secondary separation pressure and temperature are 5-8MPa and 30-40DEG C, respectively, and the corresponding products are water and safflower seed oil. And it has high extracting speed, the safflower seed oil product has no extractant remaining and has high purity, and the unsaturated fatty acid content can reach above 90%, where the linoleic acid content is about 85%.
Description
Technical field
The present invention relates to the extracting method of a kind of safflower oil, relate in particular to and a kind ofly utilize the CO 2 fluid under the supercritical state to make extraction agent, from the safflower seed, extract greasy method based on linolic acid.
Background technology
Semen Flos Carthami is the seed of feverfew safflower, and China's safflower cultivated area mainly concentrates on Xinjiang at 3～40,000 hectares, is provinces such as Sichuan, Yunnan secondly.Safflower oil is the vegetables oil that extracts from the safflower seed, and its linoleic acid content is the highest in all vegetables oil, contains flavones, vitamin-E isoreactivity material in addition.Linolic acid be unique a kind of needed by human and can not be in vivo synthetic lipid acid voluntarily, be the essential factor of keeping brain and neural function.Long-term edible linolic acid energy vessel softening reduces the absorption of gi tract to cholesterol, and it can be excreted; Simultaneously can antithrombotic and reducing blood-fat, prevent atherosclerosis; Can also prevent canceration in addition and suppress the tumour cell transfer, suppress the abnormalism disease, strengthening immunity prolongs life.Therefore safflower oil is considered to one of best in the world edible oil.
At present, the Semen Flos Carthami oil-producing technique is based on the pre-press for extracting juice-lixiviation process of peeling off.In the expressing process, even use cold-press, the seed intensification of also unavoidably being heated in extrusion process makes the nutritive ingredient deterioration by oxidations such as flavones, vitamin-E of biologically active; In the leaching process, because the introducing of organic extractant such as ethanol, sherwood oil, normal hexane etc., residual inevitably a small amount of organic extractant in the grease of leaching makes product be subjected to Organic pollutants.Can find out that by above factor at present the safflower oil extracting mode has the destruction nutritive ingredient, produce problems such as extraction agent is residual.
When critical temperature Tc (31.1 ℃) that is higher than it respectively when the temperature T and the pressure P of carbonic acid gas and emergent pressure Pc (7.39MPa), be called supercritical co.Supercritical co has very strong dissolving power, can easily regulate solubility property by changing operating parameters, to improve product purity, increases productive rate.The carbonic acid gas critical temperature is low, is specially adapted to separating of thermo-sensitivity and the unstable natural product of chemical.Carbonic acid gas is with low cost in addition, and the inertia noresidue also has anti-oxidation, suppresses effects such as bacterium.
Sun Chuanjing etc. (CN 1102646C) have reported that supercritical co oppositely extracts the result of part medicinal plant oil, but do not relate to raw material safflower seed, also the example of not producing at full scale plant.Still the method that does not have the supercritical carbon dioxide extraction safflower oil in actual applications.
Summary of the invention
The objective of the invention is to provides the preparation method of the safflower oil that a kind of technical process is simple, easy to operate, quality product is high, yield is high at above-mentioned traditional technology weak point.
Major technique feature of the present invention be with nontoxic, be easy to get, cheap carbonic acid gas is extraction agent, extracting safflower oil using under supercritical state, step-down step by step simultaneously realizes that safflower oil separates voluntarily with carbonic acid gas, carbonic acid gas recirculation is used.
The method of extracting safflower oil using of the present invention comprises the steps:
(1) be raw material with the safflower seed, it is crushed to granularity is 0.3-0.5mm;
(2) the safflower seed after will pulverizing places the extractor of supercritical extraction unit, as extraction agent, is 20-28MPa at pressure with supercritical co, and temperature is to extract under 35-60 ℃ the condition;
(3) carry out two-stage decompression separation, flash trapping stage pressure is 9-14MPa, and temperature is 35-50 ℃, separates to obtain safflower oil; The secondary separating pressure is 5-8MPa, and temperature is 30-40 ℃, obtains water and safflower oil.
Protein and amino acid that residue after the extraction is rich in do not change in extraction process, can be made into feed through further processing.
The present invention has passed through the checking of laboratory to the industrial extraction device
Advantage of the present invention:
1. the safflower oil purity height of supercritical carbon dioxide extraction gained, the content of unsaturated fatty acids can reach more than 90%, wherein contains linolic acid about 85%;
2. rate of extraction of the present invention is fast, can finish extraction and sepn process in the short period;
3. do not use organic extractant aborning, no extraction agent is residual in the product;
But 4, disease such as product vessel softening of the present invention, the control heart, cerebrovascular disease and liver cirrhosis
