Abstract
The prevalence of diabetes and obesity have risen in Malaysia due to increase consumption of food with high sugar content or high glycemic index food. Sugar act as a significant basic ingredient in a food product by imparting the sweetness and the function of sugar. The objective of this study was to determine the in vitro glycemic response and sugar composition on selected types of commercial sugars in Malaysia. Eight types of commercial sugar samples were analyzed using HPLC to determine the sugar composition. While the estimated glycemic response of all sugar samples was determined using the in vitro method and indicated as dialyzable glucose concentration at 120 minutes. The in vitro method used about 0.25g total carbohydrate available carbohydrate of the sugar samples, which was determined by clegg anthrone method. All sugar samples contained a high amount of sucrose content compared to fructose and glucose, which was highest in icing sugar (99.84% ). Palm sugar had the highest fructose ( 1.50%) and glucose (2.19%) content compared to other types of sugar samples. The dialyzable glucose concentration was highest in sugar in sachet (3.47mg glucose) but lowest in sugar with stevia (0.49mg glucose). There was no significant correlation between the estimated in vitro glycemic response and sugar composition of selected types of sugar samples. These results might be influenced by the sources of sugar, the processing of raw sugar and the polyphenol compounds in the raw sugar. In general, the study indicated that sugar composition on a selected type of sugar sample does not affect the glycemic response. Further studies related to the glycemic index of these sugars are needed especially using in vivo method to achieved a more presentable and reliable data.
