| Summary: | Palm oil is one of Indonesia’s and the world’s more important commodities, as it is used
in many industries, from food to cosmetics and transportation. As the demand for palm
oil products increase, new ways of processing palm oil are needed. In response to this
growing concern, a new standard of processed palm oil, Industrial Palm Oil (IVO) was
introduced.
Traditionally, most CPO produced is processed into Refined Bleached Deodorised Palm
Oil (RBDPO), a highly refined, clear, and odourless product fit for use in many consumer
applications. However, much of the beta-carotene is removed in this application due to
consumer tastes; IVO does not require the removal of beta-carotene. The removal of betacarotene stems from the bleaching process, which uses bleaching earth (BE) typically
made of bentonite. The state-of-the-art for BE today is acid-activated BE, where bentonite
is activated by immersion in mineral acid under high temperatures and low pressure. This
removes a lot of the beta-carotene.
This paper aims to develop a bentonite-based adsorbent by activation using an activating
agent, namely hydrochloric acid, and potassium hydroxide. The performance of the
adsorbent will be analysed by measuring certain key properties of the IVO, such as
phosphorus, iron, chloride and alkali metal content, using UV-Vis spectrophotometry,
atom absorption spectrophotometry and ion exchange chromatography techniques. The
adsorbent properties will also be analysed using isotherm adsorption.
Results show KOH-activated bentonite as a promising alternative to acid-activated
bentonite. While performance in other key areas is comparable, KOH-activated bentonite
manages to retain more carotene than HCl-activated bentonite, while having a positive
correlation between carotene retention and activation concentration. |
