为比较不同加热温度和处理方式对灰枣活性成分和抗氧化活性影响,分别对60℃热风干燥、80℃巴氏杀菌、110~140℃烘烤、100℃隔水蒸制及100℃煮制灰枣的总酚、总黄酮、总原花青素、单体酚、三萜酸含量和抗氧化活性进行测定。结果表明,灰枣...为比较不同加热温度和处理方式对灰枣活性成分和抗氧化活性影响,分别对60℃热风干燥、80℃巴氏杀菌、110~140℃烘烤、100℃隔水蒸制及100℃煮制灰枣的总酚、总黄酮、总原花青素、单体酚、三萜酸含量和抗氧化活性进行测定。结果表明,灰枣经60℃热风干燥、80℃巴氏杀菌、100℃隔水蒸制和100℃煮制后,其活性成分含量和抗氧化活性下降。110~140℃烘烤灰枣活性成分含量随温度升高呈现上升趋势,经140℃烘烤后,其总酚、总黄酮、总原花青素和总三萜酸含量分别达到341.3、473.8、659.3和560.4 mg UAE/100 g m_(d)。烘烤处理增强了灰枣的抗氧化活性,经130℃烘烤灰枣DPPH·清除能力为62.97 mmol TE/100 g m_(d),ABTS^(+)·清除能力为47.96 mmol TE/100 g m_(d)。经130和140℃烘烤后,灰枣中活性成分含量较高,抗氧化活性较强,因此烘烤也是较为合适的灰枣加工方式。展开更多
