The corn hull dietary fiber was decomposed into their components such
as cellulose, hemicellulose-A, -B, -C, -other and lignin by the Siegel
method, and their contents were 16%, 1%, 57%, 14% and 2%, respectivel
y. The components of ordinary corn fiber were insoluble in water, but
several decomposed fractions were able to dissolved. The solubility in
water of hemicellulose-B was well and of hemicellulose-A was slightly
, but other fractions were insoluble. Hemicellulose-A, -B, -C and -oth
er fractions were made up of about 30% of arabinose and 50% of xylose.
Uronic acid contents and solubility in water of each hemicellulose fr
action were mutually related.
