| Abstract: | Taken carrot as a raw material of our experiment, we experimentally studied the characteristics of microwave power, drying temperature and material thickness during a microwave-vacuum drying process by using the uniform design method, analyzed the moisture content and the carotenodis content under different experimental conditions, obtained their drying curves and the retainable mass curve of carotenodis. The regression equations of drying rate and the t carotenodis content changing with various factors were given, which were used to describe carrot microwave-vacuum drying characteristics. |
