中文摘要:

比较了单独射频、单独热风和射频-热风联用对小包装胡萝卜丁的杀菌作用，研究了射频-热风联用在不同极板间距、不同杀菌时间的杀菌效果，以及射频-热风联用对胡萝卜丁脆度、硬度、色差、类胡萝卜素含量等品质，以及总体感官评价的影响。实验研究证实，射频-热风联用不但对胡萝卜丁具有显著的杀菌效果，而且有助于保持成品的品质。

英文摘要:

The radio frequency(RF) combined with hot air has been referred to RF-hot air. The impacts of separate RF，hot and RF-hot air sterilization of carrots in a small package was studied. During the RF-hot air sterilization The effects of sterilization with different plate spacing and time，and the change of quality of carrots after been sterilized in different conditions，such as crispness，hardness，color，carotenoids and overall sensory evaluation.were evaluated by RF-hot air. The results showed that RF-hot air not only significantly influence the d bactericidal of carrots，but also maintain the good quality of the products.
