Impacts of RF-Hot Air Sterilizing on the Quality of Carrots in a Small Package

Abstract:

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.
