长茎葡萄蕨藻营养成分分析

Analysis of Nutrient Composition of Caulerpa lentillifera

[目的]分析长茎葡萄蕨藻营养成分。[方法]选用深圳某养殖场不同生长期的长茎葡萄蕨藻,测定其蛋白质和氨基酸含量组成,分析主要营养成分。[结果]不同生长期的长茎葡萄蕨藻中氨基酸含量无明显差异;长茎葡萄蕨藻中蛋白质含量为235.8 g/kg(以干重计)、氨基酸含量为204.7 g/kg(以干重计);其中氨基酸含量较高的为呈味氨基酸Glu、Asp、Gly,氨基酸组成符合世界卫生组织推荐的理想蛋白模式谱,长茎葡萄蕨藻的必需氨基酸总量高于FAO/WHO氨基酸模式谱,其SRC值为70.3。[结论]长茎葡萄蕨藻含有丰富的营养价值,具有良好的食用及相关应用前景。

[Objective]To analyze the nutritional components of Caulerpa lentillifera.[Method]The protein and amino acid contents of Caulerpa lentillifera in different growth periods from a farm in Shenzhen were determined,and the main nutrient components were analyzed.[Result]There was no significant difference in amino acid content of Caulerpa lentillifera in different growth stages.The protein content of Caulerpa lentillifera was 235.8 g/kg(dry weight),amino acid content was 204.7 g/kg(dry weight),the amino acid ratio was reasonable and the variety was complete.The amino acid composition with higher content was flavor amino acid Glu,Asp,Gly,the amino acid composition was in accordance with the ideal protein model,the total essential amino acid content of Caulerpa lentillifera was higher than that of FAO/WHO amino acid model,the SRC value of Caulerpa lentillifera was 70.3,and it has high nutritional value and utilization ratio.[Conclusion]Caulerpa lentillifera is rich in amino acids and proteins,with high nutritional value and edible value and good application prospect.
