2.4. Cooking property
The cooking properties of noodles were determined as described
in the AACC-approved method (AACC, 1976). Noodles (10 g) were
added to boilingwater (500 mL). After boiling for 10 min, the cooked
noodles were left to stand for 5 min to drain and were thenweighed.
For drying the noodles, cooked noodleswere kept at 40 C overnight.
The cookingwater (10 mL)was put into an aluminum dish and dried
to a constantweight in a 105 C oven. The cooking losswas expressed
as a percentage of solid loss during cooking. In addition, the turbidity
of the collected water was measured at 675 nm. Noodle samples
were prepared in duplicate. Cooking loss (%), water absorption (%),
and swelling index were calculated as follows.
