| Abstract For this study 47 samples of crude palm oil (CPO) were collected, consisted of what had been used for 4 hours around the city of Salvador-Bahia. To evaluate the quality of CPO were analyzed: Total Polar Compound (TPC; %) by Adsorption Chromatography (AC), Testo 270 and Fricheck; Free fatty acids (FFA; % oleic acid), Color (CIELab); Total Carotenoids (TC; ppm), induction time (IT, h) and fatty acids composition (g 100 g-1). The TPC analysis by Testo 270 and Fricheck showed a poor linear correlation with AC (0.69 and 0.60 respectively). Otherwise 44.70% and 36.95% of samples were completely oxidized, according to CA and IT methods. All samples presented TC (11.01-331.45 ppm) and yellow color predominance. Trans fatty acids, C18:1t in 17.02% and... |

| Abstract Crude palm oil (CPO), refined palm oil (RPO), refined palm olein (RPOL) and refined palm stearin (RPS) were stored in three conditions: kept away in dark (at 20-25 °C, acclimatized environment); in a refrigerator (4-8 °C); and at room temperature (26-32 °C), exposed to natural light. Free fatty acids (FFA; %), peroxide value (meq O2/kg), induction period (h), total carotenoids (ppm) and color measurements (CIELab) were analyzed to determine stability of oils every months until 12 months. All of the crude/refined initial oils were of good quality, except for one sample of CPO. Storage at 26-32 °C and exposure to light intensified the oxidative reactions. The estimated shelf life of CPO, RPO, RPOL and RPS, when stored at 20-25 °C and in the dark,... |

| Cooking oil in Indonesia is considered to be one of the staple food of Indonesian people. In the beginning of 2008, the price of cooking oil in Indonesia has increased significantly. One of the reasons is the increase of Crude Palm Oil (CPO) price in the international market. The objective of this research is to investigate the impacts of international price of CPO on the domestic price of CPO and cooking oil. Three specific objectives are included (1) To test whether international price of CPO and domestic price of CPO and cooking oil are related through cointegration tests, (2) To test the causal relationships between international price of CPO and domestic price of CPO and cooking oil and (3) To analyze how domestic price of CPO and cooking oil food... |
