摘要
以提高板兔质量为目的 ,采用自行研制的小型气调干燥机 (QTM)实验设备 ,分别以氮气、二氧化碳气体及氮气和二氧化碳气体体积各为 5 0 %的混合气体置换部分空气作为干燥介质对板兔进行气调干制试验。采用正交实验 ,分析了不同状态的气体成分对板兔干制品质量的影响。结果表明 :降低干燥室气体的氧气含量可显著降低板兔干制品过氧化值和酸价 ,提高板兔质量。在气体的氧气含量相同状况下 ,充氮降氧效果最好。此外 ,还对板兔充氮降氧干燥过程的状态参数进行了优化。
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 N 2, CO 2 and a mixture of 50% N 2 and 50% CO 2 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 O 2 content in the drying media. Quality of dehydrated salted rabbit with N 2 as medium was better than that with CO 2 and the mixture of N 2 and CO 2. A regression analysis of rabbit by CAD with N 2 as medium was carried out and a mathmatical model was obtained.
