| Abstract: |
| To study the nutritive value of Macaranga adenantha Gagnep.seed, the 1 000 seeds mass， contents of water,crude fat, crude protein,amino acid composition and content, and five mineral element of Macaranga adenantha Gagnep. seed,and the fatty acid content and composition of the seed oil were determined by the relevant national standards and conventional methods. The results showed that the 1 000 seeds mass，and content of water ,crude oil, crude protein of Macaranga adenantha Gagnep. seed were 25.657 g, 8.70 g/100 g, 2.20 g/100 g and 6.90 g/100 g,respectively. Sixteen kinds of amino acids were detected in Macaranga adenantha Gagnep. seed, and seven kinds of essential amino acids accounted for 38.06% of the total amino acids. The ratio of essential amino acids to non-essential amino acids was 61.44%, and the ratio coefficient score of essential amino acids (SRC value) was 61.83, indicating high nutritional value of Macaranga adenantha Gagnep. seed. Ca and Fe were higher mineral elements in Macaranga adenantha Gagnep. seed，with contents of 7.84×103 mg/kg and 50.60 mg/kg respectively. Fourteen kinds of fatty acids were detected from Macaranga adenantha Gagnep. seed oil, six of which were saturated fatty acids, accounting for 14.26%, mainly palmitic acid (9.21%), and eight kinds of unsaturated fatty acids, accounting for 85.66%, mainly oleic acid (35.60%) and nervonic acid (18.10%). In conclusion, there is a certain economic value and a good prospect of development of Macaranga adenantha Gagnep.seed. |
