Abstract
The preparation includes one step of adsorption with adsorbent and features that supercritical fluid extraction with CO2 or propane as supercritical fluid and the repeated two stage separation before adsorption. The preparation process in simple and can remove fish smell of fish oil completely while maintaining the original state of natural nutritive matters, raising the content of EPA and DHA in oil fish. The fish oil is high in quality.
Description
The present invention relates to a kind of fish oil, particularly relate to a kind of preparation method of high-grade fish smell-eliminating fish oil.
Omega-3 polyunsaturated fatty acids in the fish oil is that human body can not the synthetic biologically active substance, and its feature lipid acid timnodonic acid (EPA) and docosahexenoic acid (DHA) have prevention and treatment cerebral thrombosis, atherosclerosis, improvement memory, improve effects such as IQ.Therefore, the fish oil goods that are rich in EPA and DHA are rare natural health-care products, also are the essential nutrition of biological children's phase.But existing product has stench flavor, has not only influenced human consumer's acceptability, and the material of the stench flavor of some tool is to the toxic effect of human body, thereby has limited its range of application.At present, both at home and abroad, mainly adopt absorption method, water vapor deodorization method and molecular distillation method to the removing of the stench flavor of fish oil material, but these methods to take off raw meat, deodorising effect all good inadequately.
The preparation method who the purpose of this invention is to provide a kind of high-grade fish smell-eliminating fish oil, it can remedy the above-mentioned deficiency of existing method.
A kind of preparation method of high-grade fish smell-eliminating fish oil comprises a kind of adsorbent step of using, and it is characterized in that earlier fish oil being carried out supercritical fluid extraction before absorption, then separates, and circulates with this.
Method of the present invention is simple, and is easy to operate, the stench flavor material in the fish oil can be removed fully, kept the original form of the natural nutrient substance of fish oil again, also improved the content of EPA and DHA in the fish oil simultaneously, the quality height of product, and quality is good.
Below by embodiment the present invention is described.
3kg is contained EPA and DHA change in the extraction kettle greater than 30% ethyl ester type fish oil, carry out supercritical fluid extraction under 35 ℃ and 18MPa pressure, used supercutical fluid is CO
2, the stench flavor material that extracts carries out flash trapping stage under the condition of 45 ℃ and 8MPa pressure in the flash trapping stage still, enter the secondary separating still then, and carries out secondary and separate under 45 ℃ of conditions with 6MPa pressure, at last the CO that comes out from the secondary separating still
2By the adsorption column of gac is housed, further remove CO again
2In the material of residual a small amount of stench flavor.CO by this adsorption column
2After cooling, pump into extraction kettle again and carry out supercritical CO
2Extraction circulates with this, and its flow is 200kg/h, and extraction finishes after 1 hour.The fish oil that stays in the extraction kettle is high-grade fish smell-eliminating fish oil.
Used CO of one step of extraction in the present embodiment
2Can use propane instead.The optimum temps of extraction is 35～120 ℃, and optimum pressure is 4～30MPa; The optimum temps of flash trapping stage is 40～80 ℃, and optimum pressure is 4～8MPa; The isolating optimum temps of secondary is 40～80 ℃, and optimum pressure is 2～6MPa.Used sorbent material is gac, silica gel, molecular sieve or diatomite.
Claims (4)
1. the preparation method of a high-grade fish smell-eliminating fish oil comprises a kind of adsorbent step of using, and it is characterized in that earlier fish oil being carried out supercritical fluid extraction before absorption, then separates, and circulates with this.
2. the method for claim 1 is characterized in that the used supercutical fluid of described supercritical fluid extraction is CO
2Or propane; The optimum temps of extraction is 35～120 ℃, and optimum pressure is 4～30MPa.
3. the method for claim 1 is characterized in that the described flash trapping stage that is separated into separates with secondary, and the optimum temps of flash trapping stage is 40～80 ℃, and optimum pressure is 4～8MPa; The isolating optimum temps of secondary is 40～80 ℃, and optimum pressure is 2～6MPa.
4. the method for claim 1 is characterized in that described sorbent material is gac, silica gel, molecular sieve or diatomite.
