Abstract:
This study was aimed to determine whether fenugreek seed powder and fenugreek seed
extract could reduce the glycemic response when added to chapati. Through sensory
analysis, 7.5% fenugreek powder incorporated chapatti and 10% fenugreek extract
incorporated chapatti was found acceptable to taste. 9 healthy human subjects were
given glucose (reference food, twice), chapatti (0 %, 7.5 % fenugreek seed powder and
10 % fenugreek seed extract) on 5 different occasions after 10-12 hours fasting. All the
test food contained 50 g carbohydrate. Finger prick blood samples were collected at 0,
15, 30, 45, 60, 90 and 120 min after the start of the meal using glucometer.
Addition of 7.5 % fenugreek powder lowered the glycemic index of chapati by
29.8% and glycemic load by 46.72%. Addition of 10% fenugreek seed extract lowered
the glycemic index by 2.9% and glycemic load by 12.9%. The glycemic index of
chapati with 7.5% fenugreek seed powder (50.71±10.83) is significantly different (p
<0.05) than that of control (72.24±6.04). But there is no significant difference (p >0.05)
in glycemic index of chapati with 10% fenugreek extract (70.14±8.98) and control.
Glycemic load of fenugreek powder incorporated chapati (7.31±1.56) and fenugreek
extract incorporated chapati (11.94±1.53) is significantly different from that of control
(13.72±1.14). This present finding indicates that glycemic response of chapati can be
improved by incorporating fenugreek seed.
