Sugarcane and rice bran are the most important sources of commercial policosanol (PC) wax which exhibits a cholesterol lowering bioactivity. Both defatted rice bran (DRB) as agriculturalwaste and rice bran oil (RBO) retain a varying but significant amount of PC wax. Non-centrifugal cane sugar (NCS) has been consumed worldwide, and possesses various health benefits. It is mostly produced in hardened block form, which is not convenient for use compared with granular form. We aimed to increase PC contents of the granular sugar by adding wax extracted from DRB and RBO and to investigate the toxicity of the products. The results showed that thetotal PC contents including long chain aldehyde of products were increased to the maximum level of 147.97 mg/100 g. DRB is promising source of policosanol (6,044.7 mg/100 g). The main volatile components of developed sugar product was aldehyde and alcohol compounds. The 28 day toxicity evaluations of the developed sugar revealed no adverse effects.
