中文摘要:

      目的 分析中蜂枇杷蜜与意蜂枇杷蜜的理化指标及其抗氧化活性。方法 以江苏中蜂枇杷蜜与意蜂枇杷蜜为研究对象, 对其理化指标和总酚酸、总黄酮含量进行测定, 采用DPPH??和ABTS+自由基清除试验测定其抗氧化活性。结果 中蜂枇杷蜜和意蜂枇杷蜜的理化指标均符合GH/T 18796—2012《蜂蜜》, 中蜂枇杷蜜和意蜂枇杷蜜之间的水分、淀粉酶值、葡萄糖、果糖、蔗糖、麦芽糖、乳糖、灰分均存在差异性; 中蜂枇杷蜜的总酚、总黄酮、清除DPPH?自由基能力和ABTS+自由基能力均显著优于意蜂枇杷蜜; 枇杷蜜中总黄酮与清除ABTS+自由基能力均存在良好线性关系, 枇杷蜜中总酚与清除DPPH?自由基能力和ABTS+自由基能力均存在良好线性关系。结论 通过对中蜂枇杷蜜与意蜂枇杷蜜的理化指标及其抗氧化活性的检测, 为中蜂枇杷蜜与意蜂枇杷蜜鉴定与检测提供理论依据, 为枇杷蜜产品的开发提供理论支撑。

英文摘要:

      Objective To analyze the physicochemical characterization and antioxidant activity of the loquat honey produced by apiscerana and apismelliferaligustica. Methods Takikng Loquat honey in Jiangsu as the research objects. it physical and chemical indicators, contents of total phenolics and total flavonoid. Their antioxidant activities were determined by DPPH??and ABTS+ free radical scavenging experiments. Results The physical and chemical indicators of loquat honey produced by apiscerana and apismelliferaligustica in Jiangsu were confromed GH/T 18796—2012 honey. There were differences in water, amylase value, glucose, fructose, sucrose, maltose, lactose and ash between loquat honey produced by apiscerana and apismelliferaligustica; the total phenolics, total flavonoids, DPPH? and ABTS + free radical ability of loquat honey produced by apiscerana were significantly better than those of loquat honey produced by apismelliferaligustica. The total flavonoids and ABTS+ scavenging ability of loquat honey produced by apiscerana were significantly better than those of loquat honey produced by apismelliferaligustica. There was a good linear relationship between DPPH? and ABTS+ free radical scavenging ability. Conclusion Through the detection of physical and chemical indexes and antioxidant activity of loquat honey produced by apiscerana and apismelliferaligustica, which provides theoretical basis for the identification and detection of honey, and provides theoretical support for the development of loquat honey products.
