摘要:为了改善混合果蔬汁的品质,采用高压均质处理提高果蔬汁的稳定性。在单因素实验的基础上,运用响应面进行优化,以混合果蔬汁的稳定系数和离心沉淀率为响应值。结果表明:均质压力30Mpa、均质温度35℃、均质次数4 次,稳定系数0.964,离心沉淀率7.46%时能够达到较好的稳定性。

Abstract: In order to improve the stability of mixing fruit-vegetable juice beverage,high pressure homogenization wasused to improve the stability of mixing fruit-vegetable juice beverage. On the basis of single factor experiment,responsesurface methodology was used to optimize the stability coefficient and centrifugal precipitation rate of mixingfruit-vegetable juice beverage.The results showed that the beverage can have good stability,when the homogenizationpressure was 30Mpa,the homogenization temperature was 35℃ ,the homogenization times were 4,the stabilitycoefficient was 0.964,and the centrifugal precipitation rate was 7.46%.

Key words: mixing fruit-vegetable juice;high pressure homogenization;response surface;stability
