采用偏振光显微镜、激光粒度仪、全能稳定分析仪研究植脂末冲调性及温度和pH对冲调后乳状液的粒径及其稳定性的影响。结果表明:植脂末的冲调性好,速溶;温度对植脂末乳状液稳定性的影响显著,pH 5.6时,在30~45℃范围内,30 h后温度越高乳状液越不稳定,但是在45~60℃范围内,高温有利于乳状液的稳定;植脂末乳状液的平均粒径可以在一定程度上反映乳状液的稳定性,平均粒径越大,乳状液的稳定性越差;植脂末乳状液的稳定性随着pH的升高而升高。
採用偏振光顯微鏡、激光粒度儀、全能穩定分析儀研究植脂末遲調性及溫度和pH對遲調後乳狀液的粒徑及其穩定性的影響。結果錶明:植脂末的遲調性好,速溶;溫度對植脂末乳狀液穩定性的影響顯著,pH 5.6時,在30~45℃範圍內,30 h後溫度越高乳狀液越不穩定,但是在45~60℃範圍內,高溫有利于乳狀液的穩定;植脂末乳狀液的平均粒徑可以在一定程度上反映乳狀液的穩定性,平均粒徑越大,乳狀液的穩定性越差;植脂末乳狀液的穩定性隨著pH的升高而升高。

The solvency of non -dairy creamer and stability of its emulsion were studied by polarized light microscope, laser particle size analyzer and TurbiScan. The effects of temperature and pH on the particle size and the stability of non-dairy creamer emulsion were investigated. The results showed that non-dairy creamer was instant. Temperature had significant effect on the stability of non-dairy creamer emulsion. At pH 5. 6, the emulsion was more stable at lower temperature in the range of 30-45℃ after 30 h, however,at 45-60℃, higher temperature was beneficial to the stabilization of non-dairy creamer emulsion. To some extent, the average particle size could reflect the stability of the emulsion, with the average particle size increasing, the stability of non-dairy creamer emulsion became poor. Besides, the stability of non-dairy creamer emulsion increased with the pH rising.
