| 摘要: |
| 通过对不同海区浒苔及其与紫菜之间的比较，分析评价了江苏海区定生浒苔和漂浮浒苔的营养特性。通过主成分分析可以将江苏浒苔与其他浒苔和紫菜明显区分开，说明江苏浒苔的营养具有区域一致性。江苏浒苔具有高蛋白、低膳食纤维的特点，浒苔中钙、镁含量高于紫菜，磷含量低于紫菜。江苏浒苔的必需氨基酸含量组成适合人体需要，是良好的蛋白质来源。第一限制氨基酸为甲硫氨酸，呈味氨基酸含量达到氨基酸总量的33.6%—42.9%，具有较好的呈味特性。江苏浒苔的铅、铬离子含量较高，食用风险不容忽视。 |

| Abstract: |
| The nutrition characteristics of settled and floating Ulva prolifera of Jiangsu coasts (hereinafter the Jiangsu U. prolifera) were analyzed and evaluated by the comparison of different species from different marine areas. Featured with regional homogeneity, the Jiangsu U. prolifera can be separated from other U. prolifera in the principal component analysis. The Jiangsu U. prolifera had high contents of protein, as well as low dietary fiber content. The Ca and Mg contents were higher, while phosphorus content was lower than those of Pyropia yezoensis. The Jiangsu U. prolifera could be a good protein source for having essential amino acids that suitable for intake and had a good flavor properties as its flavor amino acids content was in high level, 33.6%-42.9% of the total amino acids. However, the food safety risk may be high as in the Jiangsu U. prolifera the lead and chromium ions were high. |
