摘要:

为研究鸡蛋牛奶布丁在凝固过程中凝胶的形成及质量,对鸡蛋牛奶布丁在凝固过程中的动态流变特性进行研究。结果表明:在凝固温度分别为75、80、85 ℃时进行动态时间扫描,得出鸡蛋牛奶布丁的凝胶过程是一个连续一级反应;当凝固温度为75 ℃时,得到的鸡蛋牛奶布丁强度最好、质构最均匀。通过动态温度扫描得出鸡蛋牛奶布丁的凝固过程可以分为诱导阶段(65~71.5 ℃)、加速阶段(71.5~88 ℃)和稳定阶段(>88 ℃)。

Abstract:

The formation process and quality of egg milk pudding were explored by studying dynamic rheological properties
during the solidification process. The dynamic time scanning was conducted at 75, 80, and 85 ℃, respectively. It was found
that the gelation process was a consecutive first-order reaction; at 75 ℃, the strength and structure of the pudding were the
best. Through the dynamic temperature scanning, the solidification process could be divided into three phases: induction
(65–71.5 ℃), acceleration (71.5–88 ℃) and stabilization (higher than 88 ℃).

Key words: egg milk pudding, gelation, coagulation, rheological properties, consecutive first-order reaction
