Abstract: Glycemic Index GI has recently gained attention as a possible tool for controlling appetite and managing weight and blood glucose levels. The current study was undertaken to determine the GI value of pulav mix that is commercially available in India. Glycemic index was calculated using glucose as the reference. The instant wheat rice pulav mix was fed to 20 selected subjects and their blood sugar responses are measured using standard blood glucose meter (One Touch Horizon) to see the effect of the test food on release of glucose. The blood sugar response to pulav mix is then compared with their response to eating pure glucose. There was a significant elevation in the post-prandial blood glucose levels upon the consumption of standard glucose and Pulav mix (t value: 4.109; p<0.001), but the elevation was more pronounced with the administration of standard glucose when compared to Pulav mix. Further the post-prandial blood glucose levels were lower in different time intervals with the administration of Pulav mix (p<0.05). Thus the mean iAUC of Pulav mix (20.90) was found to be lower when compared to standard food (37.20). The in-vitro digestibility of the test meal was conducted by using enzymatic method. The in-vitro digestibility of the test meal was found to be 68 which was within the range of medium GI. Thus the test meal which can be classified as medium glycemic food is suitable breakfast item for diabetic patients, patients with coronary heart disorders and a good breakfast for reducing weight.
