| 摘 要： | 以蛋黄粉为原料，研究了水的添加量对蛋黄粉凝胶特性的影响．采用质构仪的HDP／SR和P／36R探头对凝胶的质构特性进行了测定，研究表明加水量对蛋黄粉凝胶质构特性有显著影响；采用Ellman’S试剂法研究了加水量对凝胶表面巯基数的影响，研究表明随着加水量的增大，蛋黄粉凝胶表面巯基数随之减少．

| Abstract: | Egg yolk powder was the raw material. The influence of different amout of water added into it on its gel＇s proper- ties was studied. HDP/SR rig and P/36R rig of TA. XT Plus were used to determine the texture properties of the gel, and the optimal conditions for the gel＇s hardness, springness etc. were obtained. This research shows possitive impacts of different addition levels of water on egg yolk powder gel＇s texture properties, and its influence on gel＇s surface sulfydryl content was proved with Ellman＇s Reagent. The results showed the decrease of the gel＇s surface sulfydryl content along with the increase of the amour of water added into the powder. |
