红脚艾营养成分分析与评价

Nutritional Components Analysis and Assessment of Artemisia Verlotorum Lamotte

目的:对红脚艾营养成分及食用安全性进行分析与评价,以期为红脚艾的开发利用提供科学依据。方法:参照食品安全国家标准等测定方法,对红脚艾的营养成分、食用价值和毒理性进行分析评价。结果:红脚艾中主要营养成分排序为膳食纤维(59.6 g/100 g)>蛋白质(18.9 g/100 g)>灰分(10.0 g/100 g)>可利用碳水化合物(6.0 g/100 g)>脂肪(5.5 g/100 g),且可利用碳水化合物中未检测出总糖。红脚艾中含有Na、Zn、Ca、Fe、Mg、K、Mn等多种矿物质元素,其中Ca含量最高,达1.25×104 mg/kg。红脚艾蛋白质中含有16种常见氨基酸,7种为必需氨基酸,必需氨基酸占总氨基酸的40.97%,功能性氨基酸占总氨基酸的53.6%。红脚艾对大鼠的急性经口毒性指标为LD 50>5100 mg/kg体重,分级为实际无毒。结论:红脚艾安全无毒,为高膳食纤维、低糖低脂、高钙食品,在保健食品开发利用中具有广阔的应用前景。

Objective:In order to provide scientific basis for the development and utilization of Artemisia verlotorum Lamotte,this paper analyzed and evaluated its nutritional components and edible safety.Methods:According to the national standards of food safety,the nutritional components,edible value and toxicology of Artemisia verlotorum Lamotte were analyzed and evaluated.Results:The order of the main nutritional components in Artemisia verlotorum Lamotte was:Dietary fiber(59.6 g/100 g)>protein(18.9 g/100 g)>ash(10.0 g/100 g)>available carbohydrate(6.0 g/100 g)>fat(5.5 g/100 g),and no sugar was detected in available carbohydrate.There were many mineral elements such as Na,Zn,Ca,Fe,Mg,K,Mn existed in the Artemisia verlotorum Lamotte,of which Ca content was the highest,up to 1.25×104 mg/kg.There were 16 kinds of common amino acids in the protein,7 kinds of which were essential amino acids.Meanwhile,the essential amino acids accounted for 40.97%of the total amino acids,and the functional amino acids accounted for 53.6%.The oral acute toxicity index for Artemisia verlotorum Lamotte to rats was LD 50>5100 mg/kg body weight,which indicated that the acute toxicity of this herbal plant was classified to actually non-toxic.Conclusions:Artemisia verlotorum Lamotte is safe and non-toxic.It is a kind of food with high dietary fiber,low sugar,low fat and high calcium.It has a broad application prospect in the development and utilization for healthy food industry.
