Crystallization degrades the physicochemical properties of honey and reduces consumer acceptance. To address this issue, radiofrequency was developed to investigate the decrystallization efficiency and quality impact mechanism of rape honey. The results showed that radiofrequency significantly decreased the number and size of crystals, leading to shortening the decrystallization time to less than 10 min. The response surface optimization methodology further indicated that the highest decrystallization rate (98.72 ± 0.34 %) and lower 5-Hydroxymethylfurfural (2.45 ± 0.12 mg/kg) contents were obtained. Furthermore, radiofrequency changed the honey from a pseudoplastic into a Newtonian fluid efficiently due to the volumetric heating feature. It is worth noting that the inactivation of glucose oxidase reduced the antibacterial capacity, while the increase in total phenolic and flavonoid contents improved the antioxidant capacity of rape honey. In summary, current findings indicated that radiofrequency is a potential alternative decrystallization technology for water baths.
结晶会降低蜂蜜的物理化学性质并降低消费者的接受度。为了解决这个问题，人们开发了射频技术来研究油菜蜂蜜的抗结晶效率和质量影响机制。结果表明，射频显著减少了晶体的数量和大小，使抗结晶时间缩短至不到10分钟。响应面优化方法进一步表明，获得了最高的抗结晶率（98.72±0.34%）和较低的5-羟甲基糠醛含量（2.45±0.12毫克/千克）。此外，由于体积加热特性，射频有效地将蜂蜜从假塑性流体转变为牛顿流体。值得注意的是，葡萄糖氧化酶的失活降低了抗菌能力，而总酚和黄酮含量的增加提高了油菜蜂蜜的抗氧化能力。总之，目前的研究结果表明，射频是一种潜在的替代水浴的抗结晶技术。
