    Oil blending has been recognized as one of the most potent solution in producing vegetable oils with good storage stabilities and optimum fatty acids compositions. This study was conducted to identify the best oil blends in terms of physicochemical properties between canola, olive and palm olein oil. Canola and olive oils were blended at different ratios of 80:20, 60:40, 50:50, 40:60, and 20:80. Palm olein is stable against rancidity and oxidation thus the above blends were mixed with 20% palm olein. The 80:20 canola: olive blend shows the best properties after being mixed with 20% palm olein compared to other blends. It passed the cold stability test and has significantly the lowest cloud point of 6.0oC (p

    Cocoa beans are rich in numbers of beneficial bioactive compounds such as phenolics and
    phytosterols, which benefits to human being. The suitable extraction method is needed to
    produce high quality and quantity of cocoa butter and other bioactive compounds. There are
    many extraction method to extract these compounds such as Soxhlet extraction, supercritical
    fluid extraction, ultrasound extraction method and others. The objective of this study is to
    determine the effectiveness of the different extraction methods producing high yields of cocoa
    butter, lower oxidative value, stable phytosterols and antioxidant content. The cocoa beans were
    subjected to different extraction methods such as Soxhlet extraction (SE), Ultrasonic extraction
    method (USE), Supercritical carbon dioxide (SCO2
    ) and Supercritical carbon dioxide with cosolvent
    (SCO2
    -Ethanol). Cocoa butter extracted using SCO2
    -Ethanol has significantly (p
