Fourteen commonly available types of cane and palm sugar were analysed for antioxidant activity using
cyclic voltammetry. Five of the sugars, dissolved in phosphate buffer, showed anodic current peaks which
were indicative of antioxidant activity. The rank order of these sugars was: gula anau > gula merah > China
rock honey sugar > soft brown sugar > raw sugar. Gula anau is an unrefined palm sugar, while the other
four are from sugarcane. Soft brown sugar and raw sugar are coated brown sugars. The China rock honey
sugar contained chrysanthemum flowers, and its antioxidant properties appear to be due to these flowers
and not to the sugar per se. Pure white sugar, other rock sugars and rock honey sugars (all refined from
cane) as well as gula Melaka, an unrefined rock sugar from palm trees, had no observable antioxidant
activity. It is concluded that, from a nutritional point of view, using gula anau as a sweetener or ingredient
in foods or drinks has an added benefit owing to its antioxidant content
