中文摘要:

      目的 评价川西北草原药花蜂蜜的品质。方法 利用高效液相色谱法、微波消解-原子吸收分光光度法等技术分析川西北草原药花蜂蜜的营养成分、酶活性、总酚酸含量和有害物质残留等, 将分析结果与其他种类蜂蜜和国家卫生标准进行比较评价。结果 草原药花蜂蜜含有多种微量元素、维生素和氨基酸。淀粉酶、蔗糖转化酶、葡萄糖氧化酶活性较高, 分别为21.4 mL/(g?h)、57.9 mg/(g?h)、17.2 μg/(g?0.5 h)。总酚酸含量接近40 mg/100 g, 当蜂蜜加入量为200 μL时, 其超氧阴离子自由基和脂质过氧化抑制率分别为65%和77%。铅、农药、抗生素均未检出, 羟甲基糠醛、菌落总数、总大肠菌群数等指标值均远远小于国家卫生标准。结论 草原药花蜂蜜不仅有较高的营养价值和药用价值, 并且安全性高, 属于优质蜂蜜。

英文摘要:

      Objective To evaluate the quality of the medicinal flower honey from Sichuan northwestern grassland. Methods The nutrient compositions, enzymatic activities, total content of phenolic acid, and the harmful residues of the medicinal flower honey from Sichuan northwestern grassland were analyzed by multiple approaches including high performance liquid chromatography (HPLC), microwave digestion-atomic absorption spectroscopy and etc. The results were compared with national health standards in China and other types of honeys. Results The results indicated that the medicinal flower honey from Sichuan northwestern grassland contained multiple microelements, vitamins, and amino acids. The activities of amylase, sucrose invertase and glucose oxidase of the honey were high with the values of 21.4 mL/(g?h), 57.9 mg/(g?h), and 17.2 μg/(g?0.5 h), respectively. The total content of phenolic acid in honey was close to 40 mg/100 g. When adding 200 μL of the honey, the inhibition rates of superoxide anion free radical and lipid peroxidation were up to 65% and 77%, respectively. The hazardous substances including plumbum, pesticides and antibiotics were not detected in this kind of honey. Furthermore, the values of the hydroxymethyl furfural (5-HMF), aerobic bacterial count, and total coliform group were far lower than those of national health standards in China. Conclusion The honey has high nutritional and medicinal values with high safety, and is a kind of quality honey.
