- Abstract
The purpose of this study is to evaluate the effects of different content of carbohydrate and volume (concentration) on glycemic index (GI) of isomaltulose beverage and to provide a reference for the application of solid sports beverage and the development of sports beverage which takes isomaltulose as the raw material. Twenty healthy adult females were selected as research objects. The test was carried out according to the international standard of food GI detection. The objects were given 250 ml (20 g/100 ml), 500 ml (10 g/100 ml), 250 ml (10 g/100 ml) and 250 ml (5 g/100 ml) of isomaltulose beverage which contained 50 g, 50 g, 25 g and 25 g of carbohydrate respectively. Finger blood collected was tested for GI with YSI-1500 glucometer. Totally 1342 blood samples were collected, including the samples used in pre-experiment. GI values of 250 ml (20 g/100 ml), 500 ml (10 g/100 ml), 250 ml (10 g/100 ml) and 250 ml (5 g/100 ml) isomaltulose beverage which contained 50 g, 50 g, 25 g and 25 g of carbohydrate were 33.24 ± 2.15, 32.14 ± 2.47, 38.21 ± 6.14 and 37.55 ± 5.84 respectively; there was no remarkable difference between them. But GI of isomaltulose beverage containing 25 g of carbohydrate was relatively high. It is concluded that, the concentration of carbohydrate has no significant influence on GI. Hence to improve the competitive ability, athletes can select beverage in different concentrations according to their own needs.
