Abstract

Many quality degradation problems are related to the high O2 content of normal air atmosphere during drying. To reduce O2 content in drying atmosphere and obtain food products with high quality, modified atmosphere drying was conducted. In this study, carrots were used as experimental materials to investigate the effects of drying parameters on the drying characteristics and product quality. Results showed that the increase in drying temperature and the decrease in O2 content positively influenced drying rate and effective moisture diffusivity. High carotenoid content, ascorbic acid retention ratio, and rehydration ratio were produced with low drying temperature and O2 content. The color parameters of products were highly correlated with carotenoid content, and low color difference could be achieved as drying temperature and O2 content decreased. Drying temperature and O2 significantly influenced carotenoid content, ascorbic acid content, rehydration, and color difference of dried products. Good quality parameters were obtained only at low drying temperature under the drying condition of normal atmosphere and could be achieved at drying temperatures of 40 to 70 °C when O2 content is 5 %. Therefore, the modified atmosphere drying is a promising method to protect the quality of dried products.
