Abstract:
A part of ingested high‐amylose starch was indigestible and appeared in feces in both humans and mice. Starch from ordinary corn was not found in feces of either humans or mice. Fecal high‐amylose starch was birefringent, showed no microscopic evidence of enzymic corrosion and had the red polarization color characteristic of high‐amylose starch. The amylose content of fecal starch in both humans and mice was in the range 40 to 49% compared with an initial value of 70% in the amylomaize meal. Depending on the amount of amylomaize eaten (in baked muffins), human feces contained from 6 to 11% of high‐amylose starch. Approximately 11% of the high‐amylose starch ingested with 70 g of amylomaize meal (in baked muffins) appeared in the stool.
