中国谷子蛋白质氨基酸组成的研究

Study on Protein Content and Amino Acid Composition of Chinese Foxtail Millet

对具有代表性的416份中国谷子品种的研究结果证明,绝大多数品种蛋白质含量为10—13.99%,平均含量为11.73±1.40%.谷子品种的粳糯性及适口性与蛋白质没有内在联系.谷氨酸、丙氨酸、脯氨酸及天冬氨酸是中国谷子氨基酸的主要组成部分.本文还研究了中国谷子蛋白质氨基酸的相互关系。

Determination of the protein content of 416 typical varieties of Chinese foxtail millet (Setaria italica Beauv.) indicated that the protein content in the most varieties rangs from 10% to 13.99% ,av. 11.73±1.40%.The variance coefficient is 11.92% in the varieties.The protein content has no relationships with nonglutinous-glutinous property and palatability.In Chinese foxtail millet, the main composition of amino acid arc glu-tamic acid, alanine, proline and aspartic acid.The correlatiou analyses and the path analyses of protein and amino acid indicated that glutamic acid, proline and arginine arc main amindo acid in affecting on protein.
