Honey is a food of high importance due to its nutritional value. The effect of late harvest and pollen composition on honey quality and antimicrobial activity was studied. Different physicochemical parameters were determined as quality indicators. The HMF content, diastase activity, sugar content, antimicrobial activity, and hydrogen peroxide content were selected in current work as the crucial parameters for evaluation. The results proved that the late harvested honey sample showed a vast number of pollens from different blossom periods. The hydrogen peroxide content and antimicrobial activity of late harvested honey was significantly increased (proved by t-test), whereas the honey seems to be affected significantly from weather conditions since the HMF content was also increased. The diastase activity was proved to be lower than the respective in fresh honey, whereas no difference was observed on the sugar content. Finally, the effect of origin and processing in late harvested honey was discussed.
蜂蜜因其营养价值而备受重视。本研究探讨了晚收和花粉组成对蜂蜜质量和抗菌活性的影响。不同的理化参数被确定为质量指标。本研究选择了糠醛含量、淀粉酶活性、糖含量、抗菌活性和过氧化氢含量作为评估的关键参数。结果表明，晚收蜂蜜样品显示出大量来自不同花期的花粉。晚收蜂蜜的过氧化氢含量和抗菌活性显著增加（通过 t 检验证明），而糠醛含量的增加表明蜂蜜可能受到天气条件的显著影响。淀粉酶活性被证明低于新鲜蜂蜜，而糖含量则没有差异。最后，讨论了晚收蜂蜜的产地和加工的影响。
