Abstract

A total of 51 accessions of Gabing San Fernando (GSF) (Xanthosoma sagittifolium (L.) Schott, Melet), also known as new cocoyam, yautia, and tannia collected from 27 provinces in the Philippines, were characterized for their nutritional and anti-nutritional value. Nutritional characterization included proximate analysis, determination of starch content and calculation of food energy content, and quantification of oxalate. Proximate composition showed the following ranges: moisture, 53.34-81.01%; fat, 0.28-0.71%; protein, 2.07-6.18%; ash, 0.69-2.13%; and % nitrogen free extract, 13.31-39.11%. Starch content ranged 77.34-93.82% (dw basis) and food energy content, 322.53 to 395.26 (kcal 100/g). Oxalate, the anti-nutritional factor of GSF, ranged 78.69 to 222.13 (mg 100/g). Food energy content of the GSF accessions had high positive correlation with the starch content (R2=0.9852). GSF and cassava showed comparable amounts of fat and crude fiber. On the other hand, GSF showed superior energy and protein content, 121% and 334%, respectively, compared to cassava.
