Abstract

Irradiation D values for the natural bacterial flora of two samples of raw (bulk) honey were 7.50 and 1.91 kGy; for two samples of retail honey the D values were 5.66 and 3.49 kGy. Irradiation D values of Clostridium botulinum 62A spores inoculated into three honey samples and into water were respectively, 8.11, 9.38, 12.77, and 2.07 kGy. Similar D values for Bacillus subtilis spores were 3.42, 3.35, 4.00, and 1.43 kGy. The radiation resistance of C. botulinum and B. subtilis spores in honey and in sugar syrups was a function of water content.

摘要

两个生（散装）蜂蜜样品的天然细菌菌群的辐照D值分别为7.50和1.91千戈瑞；两个零售蜂蜜样品的D值分别为5.66和3.49千戈瑞。接种到三个蜂蜜样品和水中的肉毒梭菌62A孢子的辐照D值分别为8.11、9.38、12.77和2.07千戈瑞。枯草芽孢杆菌孢子的类似D值为3.42、3.35、4.00和1.43千戈瑞。肉毒梭菌和枯草芽孢杆菌孢子在蜂蜜和糖浆中的辐射抗性是水分含量的函数。
