Analysis of the nutritional composition in different plant parts of yacon

Abstract

Abstract: The sugar, crude fat, amino acids and mineral elements from different parts of Smallanthus sonchifolius were analyzed. The content of sugar in root, stem and leaf were very high, accounting for 73.20%, 16.66% and 14.24%, respectively, especially the content of FOS in root was abundant, reached 58.86%; the total content of amino acid in root was 259.82 mg/100 g and the vitamin was 3.54 μg/g; the content of crude protein and mineral element in leaf and stem were also very high. Therefore, the stem and leaf of S. sonchifolius were not only the sources of protein for human, but also good forage for domestic animals, which showed a potential to develop and utilize.
