Indonesia’s palm oil production in the period of 2013-2014 is increased by 6.65% (Directorate General of Plantation, 2013). A total of 6.2 million tons of CPO per year will be processed into cooking oil cooking oil to meet the needs of Indonesia, of the amounts in its processing into cooking oils requires bleaching earth with the mount 124,000 tons per year. Spent Bleaching Earth (SBE) in the bleaching process will absorb 90-98% carotene contained in the CPO so that the colors produced cooking oil becomes clearer. After the bleaching process, SBE will then be disposed of as waste cooking oil processing, although there are still a lot of carotene contained therein. As known carotene is a natural pigment that gives color orange, yellow-orange and red-orange. Based on the research that has been done by Qomariyah (2009) and Puspita (2009), the carotene content in the SBE around 2.1598 ppm. Natural pigments such as carotenoids can be used as a safe food coloring.
Meanwhile in Indonesia case of food safety related to food coloring is often the case. The use of dyes commonly used in children’s snacks. Example of non-food coloring that is often misused is Rhodamine B and methanyl yellow. The second dye is non-food dyes are carcinogenic if used in the long term. To overcome the problem of the use of harmful food dyes are increasing, then the recovery process from waste SBE carotene pigment to be used as a food coloring.
The process of recovery of waste SBE carotene is performed using a solvent commercial cooking oil or Refined Bleached Deodorized Palm Oil (RBDPO). The use of solvents in the form of cooking oil is based on one of the properties carotene slightly soluble in oil and also to correct previous research that did carotene recovery process using an organic solvent such as petroleum ether, n-hexane or acetone are not safe to eat because it was feared there would be residue solvent in the extract. Therefore, using cooking oil as a solvent, it is expected the resulting extract is safe for consumption.
This work is the result of the Student Research Agricultural Technology, Faculty of Agriculture, University of Brawijaya, Malang. Result of this study was Carotene Dye (Karodye) which is the result of natural food colorant carotene recovery of waste spent bleaching earth. Carotene dye is natural and do not contain toxic compounds have the potential to be applied to foodstuffs in both scale food industry and households in Indonesia so as to assist the government in an effort to reduce cases of the use of synthetic dyes in food, dyes Karodye relatively affordable because the raw materials used This is a waste for utilization can be said to be rare, the use of waste as a dye spent bleaching earth can help the government in reducing the amount of waste CPO processing. In addition, carotene dye produced according to standards and quality has proven not to contain toxic because of the research done with ingredients and food grade process regulated in such a way so as not to produce a compound food processing byproducts that are harmful if consumed, so it can be applied in foodstuffs.
Profits, advantages, and benefits derived from this Karodye are as follows:
Can reduce the amount of waste spent bleaching earth growing year has increased, due to equipment design UB staff is much cheaper than the imported equipment as desired capacity and product quality standards.
• Dye Carotene is a natural food dye.
• The quality meets the quality standards of food dyes, proved to have done assay total carotene and beta-carotene, free fatty acids and peroxide according mentioned in SNI.
• Price carotene dye is relatively low because the pigment carotene extracted from spent bleaching earth from waste cooking oil industry.
• As one of alternative solutions to waste problems of spent bleaching earth in Indonesia
• As one alternative to reduce the use of synthetic dyes in the food industry and the people of Indonesia
• Provide a new innovation for palm oil companies in order to utilize the waste spent bleaching earth so as to create a new product in the form of food coloring.
