Analysis of Antioxidant Activity and Mineral Elements in Different Tissues of Passion Fruit
摘要
Abstract
[Objective]The low-value utilization of passion fruit by-products causes environmental pollution and waste of resources.It is crucial to clarify the accumulation of nutrients in purple(TN type)and yellow(QM type)passion fruit juice,peel,and seed in order to achieve green recycling of passion fruit by-product resources.[Method]The semi-inhibitory concentration of DPPH·and ABTS+·,Fe3+ reduction ability,total phenolics,total flavonoids and mineral element contents in different tissues of passion fruit were determined,and the antioxidant capacity,active substances and mineral element contents in different tissues of passion fruit were analyzed by cluster analysis and correlation analysis.[Result]It was found that in different tissues of passion fruit,the DPPH·,ABTS+·scavenging ability,Fe3+ reducing ability,total phenolic and total flavonoid contents of fruit seeds were higher than those of juice and peel,the DPPH·scavenging ability of TN passion fruit seeds was about 37.87 times and 29.06 times of that in juice and peel,respectively.In general,the contents of total phenols and total flavonoids in TN passion fruit were higher than those in QM passion fruit.The contents of mineral elements K,Ca,B,Mn and Fe were the highest in fruit peel and the lowest in fruit seed.The content of K element in fruit peel was 10.16 times of that in fruit seed.The contents of Mg,P,Zn and Cu were the highest in fruit seeds,the content of Zn in fruit seeds was 49.06 mg/kg,which was 3.11 and 3.71 times of that in fruit juice and peel.The content of Cu in fruit seeds was 6.88 and 5.59 times of that in fruit juice and peel.Mg,P,Zn and Cu were the highest in fruit seeds.There was a significant positive correlation between Mg and P,Ca,K and Ca,and a significant negative correlation between K and P(P<0.01).The absorption and metabolism of trace elements B and Mn,Fe,Cu and Zn,Mo were promoted by each other.Major elements K and Ca mainly promoted the absorption and metabolism of B,Mn and Fe,and Mg and P mainly promoted the absorption and metabolism of Cu,Zn and Mo.A large number of elements Mg,P and passion fruit total phenol,total flavonoids content,Fe3+ reduction ability and DPPH·clearance rate,trace elements Cu,Zn,Mo and passion fruit antioxidant capacity have a significant synergistic effect,while K,B has a certain antagonistic effect on passion fruit total phenol,total flavonoids accumulation.[Conclusion]Passion fruit seed has the strongest antioxidant capacity,the highest content of active substances and trace elements,and the content of macroelements in peel is high.The mineral elements Mg,P,Cu,Zn and Mn are synergistic with active substances and antioxidant capacity.The by-products of passion fruit seed and peel can be used as important raw materials for extracting active substances.关键词
