Abstract
The present invention relates to a method for extracting oyster oil. The method comprises the following steps that fresh oyster meat shelled is minced, processed by vacuum freeze drying and pulverized into powder; then the powder is extracted by using a supercritical fluid extraction method under the conditions of a certain temperature, pressure, flow speed, etc., by using a carbon dioxide extracting agent with an additional modifying agent, namely ethanol. The method has the advantages of simple technology, easy operation, rapid extraction speed, high extraction rate, cyclic usage of the extracting agent and low energy consumption; the extracted oyster oil is a good raw material for extracting EPA and DHA, and active protein, taurine, complex carbohydrate, etc., can be also processed and extracted by the extracted meat residue.
Description
The present invention is a kind of method of extracting oyster oil, belongs to halobiontic deep process technology, particularly the processing technology of oyster.
Lipid content in the Oyster is about 11.5 grams/100 gram dry powder, wherein contain abundant omega-3 unsaturated fatty acid, the DHA (docosahexaenoic acid) docosahexenoic acid (DHA) and the timnodonic acid (EPA) that particularly it has often been said account for 1/4th of fatty acid content, but also contain many saturated fatty acids, account for 1/3rd.Therefore, the oyster oil that extracts also needs reprocessing, and the content that reduces its saturated fatty acid just can meet the high request of modern grease healthcare products.Except that containing abundant omega-3 unsaturated fatty acid; also contain many chemical ingredientss in the Oyster with medical treatment and health nutrient value; as protein, taurine, compounding sugar and multivitamin etc., in the process of extracting oyster oil, should not destroy these chemical ingredientss.The available technology adopting pure carbon dioxide extracts (referring to the clear 61-78899 of Japanese Patent: カ キ meat オ イ Le manufacture method, the i.e. manufacture method of Oyster oil) as extraction agent, but extraction rate slow (about 11 hours), extraction yield low (being about 47%).
Purpose of the present invention is exactly in order to overcome the existing shortcoming that oyster oil technology extraction rate is slow, extraction yield is low of extracting, a kind of other chemical ingredients that has medical treatment and health nutrient to be worth that can extract at a lower temperature, not destroy in the Oyster of research invention, extraction rate is fast, the method for the extraction oyster oil that extraction yield is high.
The present invention realizes by following technical proposals: mashed with the dumpling meat machine fresh oyster hinge of will shelling, vacuum lyophilization 9～12 hours, with meat mincer it is ground into dry powder again, the oyster dry powder that crushes is extracted with supercritical fluid extraction, extraction agent is the carbonic acid gas that has added the properties-correcting agent dehydrated alcohol, the weight percent content of properties-correcting agent ethanol in carbonic acid gas is 2～8%, the addition of properties-correcting agent is controlled by the properties-correcting agent compression pump, extraction temperature is 35～50 ℃, and extracting pressure is 250 * 10
5～400 * 10
5Pascal (250～400bar); When pressure rises to predetermined pressure 250 * 10
5～400 * 10
5Pascal (250～400bar) time, first static extracting 8～12 minutes, promptly the constant voltage static extracting is 8～12 minutes, and extraction agent was with the flow velocity dynamic extraction of 1～2ml/ (gram oyster dry powder minute) 30～120 minutes then; The preferred temperature of extraction should be 40～50 ℃, and the preferable pressure of extraction should be 300 * 10
5～400 * 10
5(300～400bar), extraction products therefrom oyster oil sprays in the collector through the decompression throttling valve pascal; Extract oyster oil Oyster slag afterwards and also can further process extraction active protein, taurine and other active substance of compounding sugar.
The present invention compared with prior art has following advantage and beneficial effect: (1) technical process of the present invention and operating process are simple, easy to operate, and rate of extraction is fast, the extraction yield height.Carbonic acid gas can be recycled, and energy consumption is low, and is pollution-free; (2) oyster oil that extracts is to extract EPA and DHA good raw material.Meat slag after the extraction can also be reprocessed extraction active protein, taurine and compounding sugar etc. wherein; (3) the present invention is suitable for the leading portion engineering of oyster comprehensive utilization deep processing.
Embodiments of the present invention can be operated by the described method and technology scheme of top specification sheets, just can implement the present invention preferably.The contriver has a lot of successful embodiment through research and the arduous test of long period, only tabulates in shown in the table 1 for 4 embodiment below.Present method technological process is simple as seen from Table 1, and is easy to operate, and rate of extraction is fast, only is about 40 minutes under preferable condition, and extraction yield is up to about 90%.Table 1
