Chemical composition, iron bioavailability, and antioxidant activity of Kappaphycus alvarezzi (Doty).

摘要: Kappaphycus alvarezzi, an edible seaweed from the west coast of India, was analyzed for its chemical composition. It found that K. alvarezzi is rich in protein (16.24% w/w) and contains a high amount fiber (29.40% carbohydrates (27.4% w/w). showed vitamin A activity 865 μg retinal equivalents/100 g sample. contained higher quantity unsaturated fatty acids (44.50% total), which relative percentage oleic acid 11%, cis-heptadecanoic 13.50%, linoleic 2.3% 37.0% saturated (mainly heptadecanoic acid). also to be good source minerals, viz 0.16% calcium, 0.033% iron, 0.016% zinc, are essential various vital biological activities. Bioavailability iron by vitro methods efficiency intestinal conditions than stomach conditions. Ascorbic influenced bioavailability iron.
