4种浆果成分分析及抗氧化活性研究

Components Analysis and Antioxidant Activities of Four Varieties of Berries

以蓝靛果、越桔、野生蓝莓和蓝莓为研究对象,开展其理化营养品质和抗氧化活性的综合评价研究。结果表明,理化测定方面及主成分分析,蓝靛果Vc(24.86 mg/100 g)、钙(28.32 mg/100 g)、镁(15.84 mg/100 g)、灰分(0.54 g/100 g)、蛋白质(1.27 g/100 g)、粗纤维(1.69 g/100 g)含量最高,氨基酸总量最大(985.10 mg/100 g)、氨基酸种类最多(16种)、且富含7种人体必需氨基酸(缬氨酸、赖氨酸、异亮氨酸、苯丙氨酸、亮氨酸、色氨酸、苏氨酸)。在抗氧化活性物质含量及活性方面,蓝靛果具有最高的总酚含量(313.80 mg GAE/100 g),花青素含量(161.60 mg/100 g);且在ABTS和FRAP实验中表现出了最强的抗氧化活性。4种浆果中,蓝靛果的理化营养品质综合评价最高、抗氧化活性最强,是作为浆果天然抗氧化剂和功能性食品开发的最佳选择。

The physicochemical and nutritional quality,and antioxidant activities of Lonicera caerulea,bilberry,wild blueberry and blueberry were investigated.In the physicochemical components,the highest contents of Vc(24.86 mg/100 g),calcium(28.32 mg/100 g),magnesium(15.84 mg/100 g),ash(0.54 g/100 g),protein(1.27 g/100 g)and crude fiber(1.69 g/100 g)were determined in Lonicera caerulea through physicochemical determination and principal component analysis.In addition,Lonicera caerulea also has the largest content of amino acids(985.10 mg/100 g),with the varieties of amino acids were the most(16 kinds),and it contained 7 kinds of essential amino acids(valine,lysine,isoleucine,phenylalanine,leucine,tryptophan,threonine).In the aspect of antioxidant components and antioxidant activities,Lonicera caerulea had the highest total phenolic content(313.80 mg GAE/100 g)and anthocyanin content(161.60 mg/100 g).Lonicera caerulea has the strongest antioxidant activities in ABTS and FRAP experiments.Among the 4 varieties of berries,Lonicera caerulea has the highest physicochemical and nutritional quality,and the strongest antioxidant activities,which could be better choice for developing natural antioxidants and functional food in the future.
