The particle size distribution of the bentonite was not affected to any great extent by acid activation (Önal and Sarıkaya 2007b). Alkali-refined soybean oil (SO) and cottonseed oil (CSO) used for bleaching were acquired from a vegetable oil plant and used as received (Marsa, Istanbul, Turkey). Analytically pure H 2 SO
This study examined the bleaching process parameters that contribute greatly to the refining of palm oil using low cost, natural and eco-friendly adsorbent. Activated plantain peel ash was utilized to provide the concept for the adsorptive analysis. The process parameters studied include; temperature, contact time and adsorbent dosage. A …
All adsorbents (Table 1) reduced the colour of degummed crude palm oil.The highest colour removal was observed with LOM. The reason of the enhanced carotene adsorption is probably the interaction between the nuclei of LAS and carotene as shown in Fig. 2 b, bentonite with its hydrophilic surface was not very effective in bleaching of …
Palm oil contains some impurities which, if not removed, will impair the quality of the oil. The aim of this work is to develop and optimize a model that will enhance the bleaching efficiency of palm oil using acid activated 'Ngwulangwu' clay. Central Composite Design was used to optimize these process conditions (time, temperature and clay dosage) on …
