Analysis of the factors for producing dehydrated salted rabbit by controlled atmosphere drying and optimization of its processing parameters

In order to improve the quality of dehydrated salted rabbit, a small modified atmospheric dryer developed by the authors was used to conduct the experiment for processing salted rabbit, in which N₂, CO₂ and a mixture of 50% N₂ and 50% CO₂ were used as drying media to replace partial air. An orthogonal experiment was carried out to study different influence factors. The effect of Controlled Atmophere Drying(CAD) on the quality of salted habbit was analyzed. The study covers the peroxidase value, acid value under different drying conditions and optimization of processing parameters. The results showed that peroxidase value and acid value of dehydrated salted rabbit were decreased with decreasing O₂ content in the drying media. Quality of dehydrated salted rabbit with N₂ as medium was better than that with CO₂ and the mixture of N₂ and CO₂. A regression analysis of rabbit by CAD with N₂ as medium was carried out and a mathmatical model was obtained.
