摘要: 通过单因素试验、最陡爬坡试验(SAD)、中心组合试验(CCD)和响应面分析法(RSM)对再制干酪的乳化盐配方进行优化。单因素试验结果表明:柠檬酸钠、多聚磷酸钠、焦磷酸钠3种乳化盐对再制干酪的乳化效果有显著影响,利用SAD的3个显著因素的水平取值逼近最大响应区域,通过CCD和RSM确定了3个显著因素的最优水平,得到再制干酪的乳化盐配方:柠檬酸钠2.0%、多聚磷酸钠0.20%、焦磷酸钠0.37%(均以原料天然干酪的质量计),在此配方条件下,验证实验得到再制干酪的溶胶系数为62.15%,与模型预测值非常接近。采用响应面法对再制干酪的乳化盐配方进行优化合理可行。

Abstract: Single-factor tests, central composite design (CCD) and response surface methodology (RSM) were used to optimize the emulsification salt formulation for preparing cheese. The results of single-factor tests showed that sodium citrate, sodium polyphosphate and sodium pyrophosphate had an obvious emulsification effect on cheese preparation. Three significant factors were made by the steepest ascent design (SAD) to approach the maximum response area and then optimized by CCD and RSM. The optimal formulation was composed of 2.0% sodium citrate, 0.20% sodium polyphosphate and 0.37% sodium pyrophosphate (on the basis of the weight of natural cheese). Under the optimal formulation, the peptization coefficient was 62.15%, which was close to the predicted value. Therefore, RSM can provide a reliable process for optimizing emulsification salt formulation for preparing cheese.

Key words: cheese preparation, emulsification salt, peptization coefficient, response surface methodology
