摘要:

为了解不同产地百香果黄果的功能品质，为百香果大健康产品的开发、产业化应用提供参考。以贵州5个栽培产地的百香果黄果为研究对象，对百香果黄果果汁的主要功能成分和抗氧化活性进行分析研究。结果表明，5个产地样品中Vc、总黄酮、总多酚、总多糖和总花青苷含量分别在74.85~192.79 mg VcE/100g、16.06~51.85 mg RE/100g、61.32~86.92 mg GAE/100g、68.69~144.80 mg GE/g和0.12~1.23 mg CyGE/100g之间；对DPPH、ABTS和羟基自由基清除率分别在89.01~97.03%、89.14~95.59%、96.30～99.31%之间。不同产地百香果受地区气候、平均气温、年降雨量、年日照情况的影响，果汁主要功能成分含量差异显著，且Vc含量、总多糖含量、抗氧化性能均较高，对DPPH自由基和羟基自由基的清除作用趋势相同。相关性分析得出，百香果果汁中Vc、花青苷、黄酮、多酚主要可加强对DPPH自由基、羟基自由基的清除，而多糖主要可加强对ABTS自由基的清除。综合分析，相比黔南地区，黔东南地区产的百香果黄果主要功能成分含量高，抗氧化能力强，是用于开发功能性食品和保健食品的良好材料。

Abstract:

To understand the functional quality of yellow (Passi?ora edulis f. flavicarpa) passion fruit from different habitats, and provide reference for the development and industrial application of passion fruit health products. The yellow passion fruits from five cultivation habitats in Guizhou were selected as the research objects to analyze the main functional components and antioxidant capacity of the juice. The results showed that the contents of Vc, total flavonoids, total polyphenols, total polysaccharide, and total anthocyanin ranged from 74.85 to 192.79 mg VcE/100g, 16.06 to 51.85 mg RE/100g, 61.32 to 86.92 mg GAE/100g, 68.69 to 144.80 mg GE/g, and 0.12 to 1.23 mg CyGE/100g, and the scavenging rates of DPPH, ABTS and hydroxyl free radicals were ranged from 89.01 to 97.03%, 89.14 to 95.59%, and 96.30 to 99.31%, respectively. The contents of main functional components of passion fruit juice from different habitats showed significant differences, which were affected by the regional climate, average temperature, annual rainfall and annual sunshine. The contents of Vc and polysaccharide and the antioxidant activity of passion fruit juice from different habitats were all high, and the scavenging effects on DPPH radical and hydroxyl radical were similar. The correlation analysis showed that Vc, anthocyanin, flavonoids and polyphenols in the juice of passion fruit could mainly strengthen the scavenging of DPPH and hydroxyl free radical, and polysaccharide could enhance ABTS free radical scavenging. Comprehensive analysis: compared to the passion fruit produced in southern Guizhou, the content of active components in southeast Guizhou is higher and antioxidant ability is stronger. It is a good material for developing functional food and health food.
