摘要

比较分析了不同加热温度（75℃、85℃和95℃）下微波处理（MH）和水浴处理（WH）对糖基化α-乳清（GLA）乳状液稳定性的影响。与wh处理的GLA相比，mh处理的GLA褐变强度和清除DPPH的能力更强，游离氨基含量更低。与WH相比，MH显著降低了gla负载乳状液的乳化指数（CI）、平均粒径、过氧化物值（POV）和硫代巴比妥酸反应物质（TBARS）值，提高了gla负载乳状液的界面吸附比和ζ电位绝对值。此外，在95℃条件下，MH制备的GLA乳液在保存10天后仍具有最好的稳定性。这些结果表明，MH是提高糖基化蛋白负载乳的物理稳定性和氧化稳定性的较好方法。

Evaluating microwave and conventional heating on the stabilization of emulsion loaded by glycosylated α-lactalbumin

Impact of microwave treatment (MH) and water bath treatment (WH) at various heating temperatures (75, 85 and 95 °C) on the stability of glycosylated α-lactalbumin (GLA) emulsion was compared and analyzed in this work. The MH-treated GLA had stronger browning intensity and DPPH scavenging ability, and lower free amino group than WH-treated GLA. Compared with WH, MH significantly reduced the creaming index (CI), average particle size, peroxide value (POV) and thiobarbituric acid-reactive substances (TBARS) value of GLA-loaded emulsion, whereas increased its interfacial adsorption ratio and Zeta-potential absolute value. Furthermore, the emulsion with GLA prepared by MH at 95 °C had the best stability even after 10 days of storage. All these results suggest that MH is a superior way to improve physical and oxidant stability of glycosylated-protein loaded emulsion.
