| titleOfInvention | A kind of extraction method of unsaturated fatty acid |
| abstract | The invention provides an extraction method of unsaturated fatty acid, which belongs to the technical field of chemical technology. The extraction method includes the first urea inclusion on the fish oil raw material: mixing the fish oil raw material with an ethanol solution and urea, then cooling down, and separating solid and liquid to obtain a first filtrate; leaving the first filtrate to stand for stratification to obtain an unsaturated The first lower layer of crude fatty acid extract. Among them, the cooling adopts the method of vacuuming. By using vacuum to volatilize part of the ethanol to cool down, the cooling time is significantly faster than that of the traditional process. After part of the ethanol is evacuated, the utilization rate of urea is improved, thereby improving the efficiency of the entire extraction process and saving energy. |
