The effect of pre-treatment of mackery (Scomber scombrus) on oil recovery and quality was investigated. Fish oil was extracted using the screw expeller press after heat pre-treatment of the fish sample. The effect of cooking temperatures and cooking times was evaluated. It was observed that the oil yield has a positive relationship with cooking temperature. The oil yield increased with increasing cooking temperature at all the cooking times investigated and also increased with increasing cooking time from 5-15 minutes and then decreased for 20 minutes cooking time at all the cooking temperatures investigated. The results revealed that a highest yield of 22.8 % was obtained when the fish was treated at 90 0C cooking temperature for 15 minutes. The lowest... |

Coconut oil yield was found to be dependent on the following processing parameters: post heating moisture content, applied pressure, pressure duration, heating time and temperature to which the samples were subjected using hydraulic uniaxial compression. The highest coconut oil yield obtained was 51.9% at optimum condition. This yield corresponds to an expression efficiency of 81.2% of the total coconut oil content which represented 63.9% by weight of the copra (dried coconut flesh). The highest oil yield was obtained at an expression pressure of 25MPa when samples were conditioned to an initial moisture content of 11.3% w. b. and heated at 120ºC for 15min to obtain a post heating moisture of 7.13% w. b. Increases in oil yield were recorded for... |
