| Abstract: |
| Currently, given the rapid development in food industries, food quick-freezing provides high food quality and receives extensive attention. In the review, the principle of food freezing was introduced, and food quality differences between the quick-freezing process and slow-freezing process were compared. Additionally, traditional and new methods of food quick-freezing including pressure assisted freezing, electric assisted freezing, and magnetic assisted freezing were classified to examine the status and development tendency. Furthermore, the emerging methods exhibit immense application prospects from the food quality and energy consumption perspectives. The simplified methods were summarized in the simulation process to optimize the freezing process and guide experimental studies. |
