摘要:

以鲜牛奶为实验材料,以pH 值、浊度、Zeta 电位以及流变特性的变化为品质评价指标,研究不同的热-超声联合处理方式对牛奶品质的影响。研究表明,热- 超声联合处理对牛奶的品质没有负面影响,各种联合处理方式中,先超声处理后加热的处理方式下牛奶的品质最佳。

关键词: 热- 超声, 牛奶, 品质, Z e t a 电位, 浊度, 流变特性

Abstract:

Combinatorial treatments of ultrasound and heating were applied to milk sterilization. pH change, turbidity, Zeta potential and rheological properties were used to evaluate the effects of ultrasound-heating treatment on the quality of milk. Results indicated that milk quality was not deteriorated by the ultrasound-heating treatment; in contrast, excellent milk quality was achieved by a sequence of ultrasound and heating treatments.

Key words: ultrasound-heat, milk, quality, Zeta potential, turbidity, rheological property
