摘　　要：为比较和分析不同品种的甘蔗蔗汁及其制成红糖的抗氧化活性,探讨其作为功能性食品成分的潜力,本研究以14份甘蔗品种为材料,采用传统工艺熬制成红糖,测定甘蔗汁及其所制成红糖的总多酚、黄酮、DPPH自由基清除能力、ABTS自由基清除能力、总还原力、铁离子还原力(FRAP),并对其进行描述性分析、相关性分析及基于熵权TOPSIS法的抗氧化活性综合评价(该方法通过构建评价模型客观赋权并计算各样本与理想解的接近度)。研究结果表明,甘蔗品种对蔗汁及红糖的抗氧化活性有显著影响,甘蔗汁中总多酚含量在382.99~1130.46 mg/kg之间,总黄酮含量在385.40~1032.35 mg/kg之间,总多酚含量与总黄酮含量、DPPH自由基清除能力、ABTS自由基清除能力、总还原力、FRAP共5项之间全部均呈现出极显著正相关性。熵权TOPSIS法评价结果显示,F172、粤糖93159和新台糖16号品种所制成的红糖在抗氧化能力和营养品质上综合表现最优。本研究可为甘蔗及红糖的功能化开发提供科学依据。This study aimed to compare and analyze the antioxidant activities of sugarcane juice and its derived brown sugar from different varieties,exploring their potential as functional food components.Fourteen sugarcane varieties were processed into brown sugar using traditional methods.The total polyphenols,flavonoids,DPPH/ABTS free radical scavenging rates,total reducing power,and ferric reducing antioxidant power(FRAP)were measured in both sugarcane juice and brown sugar.Descriptive analysis,correlation analysis,and entropy weight TOPSIS-based comprehensive evaluation(a method involving objective weighting through model construction and proximity calculation to ideal solutions)were conducted.Results demonstrated significant varietal effects on antioxidant activities,with total polyphenol content in sugarcane juice ranging 382.99~1130.46 mg/kg and total flavonoids 385.40~1032.35 mg/kg.Highly significant positive correlations(P<0.01)were observed between total polyphenols and all five parameters:total flavonoids,DPPH/ABTS scavenging rates,total reducing power,and FRAP.The entropy weight TOPSIS evaluation revealed that varieties F172,Yuetang93159,and Xintaitang16 exhibited optimal comprehensive performance in both antioxidant capacity and nutritional quality.This research provides scientific evidence for the functional development of sugarcane and brown sugar.
