摘要
对磷脂酶A2 改性的浓缩磷脂产物乳化稳定性、抗氧化性、润湿性及HLB值的变化进行了研究。研究表明酶水解磷脂产物乳化稳定性有显著提高 ;同时具有良好的润湿性 ,使脱脂奶粉润湿下沉时间达到 5S ,速度提高 80倍 ;抗氧化性也有提高 ,较原料磷脂提高 35 .0 4 % (第 8天 ) ,且HLB值达到 8,具有较好的亲水性能 ,为磷脂的更广泛应用提供了理论依据。
The study on the function and characteristic of concentrated soybean phospholipid modified by enzyme was conducted. The wettability,antioxidation and HLB value of soybean phospholipid hydrolyzed by phosphatidease A2 is improved . The emulification stability of hydrolyzate standing is higher than that of raw material phospholipid. After hydrolyzing the soybean phospholipid's antioxdation is improved, it increases near 40 percent. The wettability is increased 80times. The HLB value of enzyme changed concentrated soybean phospholipid is 8, increasing its hydrophily. The study provide the theories basis for phosphalipid producing and applying in different fields.
