To study the effects of radio frequency-assisted hot air drying (RFHAD) on the quality of South American white shrimp (Penaeus vannamei), the RFHAD process based on the dielectric properties of the shrimp was optimized. The effects of radio frequency drying (RFD) and RFHAD on the flavor nucleotide contents and equivalent umami levels in dried shrimp were compared with those of hot-air drying (HAD). The results showed that as the temperature and moisture content increased, the dielectric constant and loss factor of the shrimp also increased, facilitating moisture migration and enhancing the drying rate. The penetration depth of the RFD was negatively correlated with moisture content, temperature, and frequency. Additionally, increasing the number of stacked layers and reducing the plate spacing significantly increased the drying rate of the shrimp (P |
