The ash contents in BF-substituted noodles (30BFG and 30BFN)
were significantly (p < 0.05) higher than those of the control (conG
and conN). The ash content depends on the quality of the flour
(Kim, 1996) and thus corresponds to the higher mineral content
(especially potassium) in BF which contributed to the significant
higher ash content in BF noodles.
After addition of 10% oat b-glucan to noodles, the contents of
crude protein, crude fat and ash were found to increase as compared
to noodles without oat b-glucan. These results indicated that
oat bran contributed certain amounts of protein, fibre and fat to
the noodles.
