【Abstract】 A series of drying tests of the tunip slice were conducted by controlled atmosphere drying and hot airflow drying. The mass fraction of vitamin C under different drying conditions were determined, and the regression equations were established on the basis of different drying conditions (hot airflow drying, controlled atmosphere drying, temperature, the volumn fraction of O 2). It was proved that the new drying instrument and the controlled atmosphere drying processing technology could increase the mass fraction of vitamin C.更多还原
