Abstract:
This study was carried out to determine the blood glucose responses of pumpkin nugget
in healthy adult. Fourteen healthy adults' subjects had participated in this study. Two
types of pumpkin nugget namely pumpkin nugget (PN) and pumpkin nugget incorporated
with 30% minced chicken (PC) were tested. The subjects were required to go through the
study protocol on three separate occasions in duplicate, for glucose reference, PN and PC
after an overnight fasting. Capillary blood samples were taken immediately before (0
min) and at 15, 30, 45, 60, 90, and 120 min after consumption of the test food. It was
found that the blood glucose response (BGR) of PN reached the peak value was 0.9
mmol/L at time 45 minutes mean while the BGR of PC was 1.1 mmol/L at time 30
minutes. The BGR of PN for male was 1.2 mmol/L at time 30 minutes and for female was
0.9 mmol/L at time 45. Hence, it was found that BGR of PC reached the peak value for
male was 1.0 mmol/L at time 45 minutes meanwhile female was 1.2 mmol/L at time 30
minutes. The iAUC of PN (85.99 ± 11.693) was significantly lower than that of PC
(I 06.99 ± 8.79b).The study found that there was no significant difference (p>0.05) in the
BGR of male subjects and female for blood glucose response for the same test meal at
different time intervals, blood glucose response for different test meal at the same time
intervals, comparison of blood glucose response between gender for PN and PC. The GI
of PN (43.87 ± 5.50) was not significantly different from that of PC (44.66 ± 5.99). This
study shows that replacing 30% pumpkin puree with minced chicken lowered the iAUC
of pumpkin nugget but did not change its glycemic index.
