In Chile, honey is produced from several native species with interesting biological properties. Accordingly, those attributes are present in Chilean honeys owing to the presence of phenolic compounds inherited from specific floral sources. In recent years, the exported volume of Chilean honeys has been increased, reaching new markets with demanding regulations directed toward the fulfilment of consumers' expectations. Accordingly, there are countries with special requirements referring to spore-free honeys. This microorganism is the pathogen responsible for American foulbrood disease in beehives; however, antibiotics are not allowed when an apiary tests positive for . On the other hand, it is mandatory to have an accurate method to remove the potential presence of spores in bee products intended for export. Exposure to ionizing radiation can be an efficient way to achieve this goal. In this work, 54 honey samples harvested from northern, central and southern Chile were analyzed for physicochemical patterns, total phenols, antioxidant activity and antiradical activity. Honeys with and without spores were exposed to ionizing radiation at three levels of intensity. Afterwards, the presence of spores and the effect on phenol bioavailability, antiradical activity and antioxidant activity were measured again. This research presents results showing a positive correlation between the percentage of prevalence of native endemic species in the set of honeys analyzed and the capacity to resist this process, without altering their natural attributes determined before irradiation treatments.
在智利,蜂蜜由几种具有有趣生物学特性的本土物种酿造而成。因此,由于从特定花卉来源继承的酚类化合物的存在,这些特性存在于智利蜂蜜中。近年来,智利蜂蜜的出口量有所增加,进入了对产品质量有严格要求以满足消费者期望的新市场。因此,有些国家对无芽孢蜂蜜有特殊要求。这种微生物是蜂箱中美洲幼虫腐臭病的病原体;然而,当蜂场检测出该病菌呈阳性时,不允许使用抗生素。另一方面,必须有一种准确的方法来去除出口蜂产品中潜在的芽孢。暴露于电离辐射可能是实现这一目标的有效方法。在这项工作中,对从智利北部、中部和南部采集的54个蜂蜜样本进行了理化模式、总酚、抗氧化活性和抗自由基活性分析。有芽孢和无芽孢的蜂蜜分别接受三种强度水平的电离辐射。之后,再次检测芽孢的存在情况以及对酚类生物利用度、抗自由基活性和抗氧化活性的影响。这项研究结果表明,在所分析的蜂蜜样本中,本土特有物种的流行率百分比与抵抗这一过程的能力之间存在正相关,且不会改变辐照处理前测定的天然属性。
