摘要
以水酶法制油工艺得到的红花籽水解蛋白为原料,对比了DA201-C、XAD1180N、D3520三种大孔吸附树脂对红花籽水解蛋白的静态吸附性能,并对其组成成分进行分析。结果表明:DA201-C树脂对水解蛋白吸附率与解吸率最高,能有效去除糖类等杂质;DA201-C树脂对水解蛋白的吸附平衡时间为2 h,吸附率为48.39%,体积分数70%乙醇解吸效果最好,解吸率为90.44%。经DA201-C树脂纯化后的水解蛋白,蛋白质含量提高了30.10%,脂肪含量降低了91.53%,糖含量降低了95.52%,色差L*值提高了11.63%,b*值降低了20.91%。
In this paper,the macroporous adsorption resins DA201-C、XAD1180N and D3520 were chosen for purifying protein hydrolysates extracted by aqueous-enzymatic extraction of safflower seeds oil. The chemical composition of purified safflower seeds protein hydrolysates was studied. The results of static adsorption performance indicated that DA201-C showed higher adsorption rate and desorption rate. The adsorption equilibrium time of protein hydrolysates was 2 h,and the adsorption ration was 48. 39%. The best desorption solvent was 70% ethanol,and the desorption rate was 90. 44%. After purification by DA201-C,the protein content in safflower seeds protein hydrolysates increased with 30. 10%,fat content decreased 91. 53%, sugar content decreased 95. 52%,L＊increased with11. 63%,b＊decreased 20. 91%.
