Abstract A complete study on the microbiological and physico-chemical properties of yatei honey (Tetragonisca fiebrigi) was carried out, focusing on the quality standards that are necessary for its commercialization. The results showed that physico-chemical and microbiological parameters of T. fiebrigi honey differed from standard values of Apis mellifera, but not from other stingless bees honey from South America. Yatei honey showed the presence of fecal contamination (Escherichia coli), and a seasonal influence in microbiological parameters, acidity, pH, sucrose and diastase activity. On the other hand, three preservation treatments were carried out and evaluated for 90 days in T. fiebrigi honey: refrigeration, pasteurization and dehumidification. Pasteurization and dehumidification of yatei honey eliminated fecal contamination while in refrigerated honey E. coli survived in time (8–90 days), unlike the samples kept at room temperature (

yateí (Tetragonisca fiebrigi) 蜂蜜的特性和保存处理：除湿、巴氏杀菌和冷藏

摘要 对亚特蜂蜜 (Tetragonisca fiebrigi) 的微生物和理化特性进行了完整的研究，重点研究了其商业化所需的质量标准。结果表明，T. fiebrigi 蜂蜜的理化和微生物参数与Apis mellifera 的标准值不同，但与来自南美洲的其他无刺蜜蜂蜂蜜没有区别。Yatei 蜂蜜显示存在粪便污染（大肠杆菌），以及微生物参数、酸度、pH、蔗糖和淀粉酶活性的季节性影响。另一方面，在 T. fiebrigigi 蜂蜜中进行了 90 天的三种保存处理并进行了评估：冷藏、巴氏杀菌和除湿。
