摘　　要：以钙结合率为指标,对从鱼糜漂洗废水中回收的肌浆蛋白肽(recycled myogenpeptide,RMP)与钙离子的结合条件进行优化。最佳结合条件为p H9、35℃、钙离子浓度4 mmol/L、RMP浓度5 g/L、反应时间1h,此时钙结合率为85.00%。RMP-Ca复合物具有较好的酸碱稳定性,在p H 5~9范围内钙保留率高达85%以上。一定的加热处理会导致RMP-Ca复合物钙保留率下降,经过121.1℃高温处理后钙还能保留70.14%。RMP-Ca复合物具有很好的抗消化性,消化后钙保留率高达95.31%。Based on binding rate,the conditions ofrecycledmyogenpeptide（RMP） from surimi wash water binding calcium were optimized as follows：RMP concentration 5 g/L,calcium concentration 4 mmol/L,temperature 35 ℃,p H 9 and reaction time 1 h. In these conditions the binding rate of RMP was 85.00 %. RMP-Ca complex owned good ability to resist p H with more than 85 % calcium retention rate at the p H range of 5-9. After heated at 121.1 ℃ for 15 min,the calcium retention rate was as high as 70.14 %. RMP-Ca complex also could resist digestion by pepsin and trypsin with 95.31 % calcium retention rate after digestion.
