摘要: 为了保持胶原蛋白的生物活性、提高得率,采用微波技术提取猪皮胶原蛋白。通过单因素试验研究微波处理温度、微波处理时间、固液比、提取时间4个因素对胶原蛋白提取率的影响,确定微波辅助提取胶原蛋白的最佳工艺条件。结果表明:微波时间2min、微波温度25℃、固液比1:30(g/mL)、提取时间35h条件下,猪皮胶原蛋白的提取率为76.72%。

Abstract: In order to maintain the bioactivity and improve the extraction rate of collagen, microwave technique was used to extract collagen from pigskin. Using one-factor-at-a-time combined with orthogonal array design method, the extraction rate of collagen was investigated with respect to temperature, microwave treatment time, material/liquid ratio and extraction time. The optimal extraction conditions were obtained as follows: microwave treatment time 2 min, temperature 25 ℃, material/liquid ratio 1:30 (g/mL), and extraction time 35 h. Under these conditions, the extraction rate of collagen from pigskin was up to 76.72%.
