Analysis of physicochemical characterization and antioxidant activity of loquat honey produced by apiscerana and apismelliferaligustica

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.
