浅谈蜂蜜的质量检测及注意事项 [内 容 摘 要] 蜂蜜是由蜜蜂采集植物蜜腺分泌的汁液酿成。其主要成分为单糖、双糖和多糖。此外，还有少量的蛋白质、氨基酸、有机酸、维生素、色素、芳香物质等。其中以单糖（果糖、葡萄糖）为主要成分约占总成分的65%以上，其次是双糖中以蔗糖占绝对优势。成熟的蜂蜜中蔗糖平均含量不超过5%，而更多的则在1%—3%左右。蜂蜜中果糖和葡萄糖因其有还原性，所以称之为还原糖。近几年来蜂蜜造假猖獗，蜂蜜国家标准钟明确规定，蜂蜜中不得添加或混入任何糖类、带糖类物质，不得添加或混入任何防腐剂、澄清剂、增稠剂等异物，并规定了对蜂蜜质量的检测方法和判定原则。本文就此对蜂蜜的质量检测及注意事项进行简要谈述。 [关键字]: 蜂蜜 质量检测 注意事项 |

[abstract] Honey is brewed by bees via collecting secretion juice from nectaries of plants. Its main components are monosaccharides, disaccharides and polysaccharides. Moreover, there is still a minor amount of proteins, amino acids, organic acids, vitamins, pigments and aromatic substances. Among all these components, the monosaccharides (fructose and glucose) as one of the main components take about more than 65% of the total composition, and followed is the predominant sucrose in disaccharides. The average content of sucrose in the mature honey is not more than 5% and about 3%-5% in most cases. Both fructose and glucose in honey are reductive, which results in their being called as reductive sugars. In recent years, manufacturing of counterfeit honey has sharply increased and become widespread. The national standard of honey clearly defines that no sugars of any kinds and substances that contain sugars are allowed to be added to or mixed with honey, nor do preservatives, clarifying agents, thickeners and the other exotic substances. In addition, the standard also defines the quality testing methods and judgment doctrines. This paper will briefly discuss the quality testing of honey and items to be noticed.
