The aim is to optimize the extraction process of tilapia fish head oil which is extracted by supercritical CO2(SC-CO2) from tilapia fish head. The signal factors were chosen by single-factor experiments and the optimal extraction conditions of tilapia fish oil by SC-CO2 were optimized by response surface method. Then, the quality and fatty acid composition of tilapia fish head oil were analyzed. The results showed that the optimum conditions were: extraction pressure 36 MPa, extraction temperature 41°C and extraction time 3.1 h, which were better than cooking method, alkali hydrolysis method and enzymic method. The extraction rate under the optimal extraction condition by SC-CO2 was 79.5%, and the iodine value, POV and acid value were 5.36±0.15 mg/kg, 4.27±0.33 mmol/kg and 139.0±8.9 g/100 g resp. The contents of saturated fatty acid(SFA), mono-unsaturated fatty acid(MUFA) and poly-unsaturated fatty acid(PUFA) were 27.85%, 41.74% and 30.41% resp. The tilapia fish head oil was rich in fatty acid, which indicated excellent nutritional value and functionality. This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Related Products of 1731-94-8).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 1731-94-8
