摘要:
分别采用沸水烫漂、蒸汽烫漂和微波烫漂处理碱蓬,测定碱蓬提取液的总酚、总黄酮、3种黄酮单体含量,以及总抗氧化能力,DPPH·、羟自由基(·OH)、超氧阴离子(O2·-)清除能力和还原能力,研究不同烫漂方式对碱蓬活性成分和抗氧化能力的影响。结果显示,在达到相同灭酶效果的情况下,微波烫漂制得的碱蓬样品中总酚、总黄酮、杨梅素和染料木素含量显著高于热水烫漂与蒸汽烫漂样品;不同的烫漂方式对碱蓬提取物的抗氧化能力有明显影响,微波烫漂制得的碱蓬提取液的总抗氧化能力,DPPH·、·OH清除能力以及还原能力显著高于热水烫漂和蒸汽烫漂法处理的碱蓬提取液(P<005),但微波烫漂样品与蒸汽烫漂样品对 O2·-的清除率无显著差异,综合考虑加工成本与产品品质,采用微波烫漂加工碱蓬更为合理。
Abstract:
The influences of blanching methods on the content of active constituents and antioxidant capacities of Suaeda salsa L. were studied by applying boiling water, steam and microwave during blanching. The ethanol extracts of S. salsa were determined for total phenolic contents, total flavone, three kinds of flavonoid monomers, total antioxidant capacity, DPPH·scavenging capacity, hydroxyl radical (·OH) scavenging capacity, superoxide anion (O2·-) scavenging capacity and reducing capacity. The results showed that, in the case of same enzyme deactivation, the total phenols contents, total flavones,myricetin and genistein in the samples subjected to microwave blanching were significantly higher than the samples subjected to boiling water blanching and steam blanching. The antioxidant capacities of S. salsa extracts subjected to microwave treatment exhibited stronger total antioxidant activity, free radical scavenging activity against DPPH· and ·OH, and reducing activity than those subjected to other two blancing treatments. No obvious difference between microwave blanching and steam blanching in O·-2 scavenging capacity was observed. Considering cost and product quality, microwave treatment was recommended for blanching.
