Green banana flour (BF), produced from Musa Awak, has potential
as source of fibre when substituted in noodle products. The
incorporation of 30% BF significantly increased the total dietary fi-
bre of noodle, resistant starch, total starch and some essential minerals,
including phosphorus, magnesium, potassium and calcium.
Besides, substitution of 30% BF in noodle increased the moisture,
crude protein, crude fibre, and ash contents. Therefore, this produced
a good quality noodle in terms of nutritional values and sensory
acceptability.
Noodles substituted with 30% BF showed lower carbohydrate
digestibility rate than did the control and had a lower GI. However,compared to the noodle with substituted 30% BF and added oat
b-glucan, it showed greater effect in retarding the rate of carbohydrate
digestibility and reducing the GI of noodles. Addition of 10%
oat b-glucan resulted in a pronounced increment of soluble fibre
content and significantly reduced the GI of noodles. Oat b-glucan
also contributed certain amounts of protein, crude fibre, crude
fat, ash, amylose and total starch to noodles.
