摘要:

基于近红外发射光谱的背反射光随时间的ΔBS 得到的SI 为评价指标,采用Box-Behnken 设计研究了果胶用量、均质压力、均质温度对褐色乳饮料稳定性的影响,回归分析得到优化参数为:果胶用量2.8g/L,均质压力21MPa,均质温度42℃。

关键词: 背散射光, 稳定性, 乳饮料, 果胶, 均质

Abstract:

Detla back scattering (Δ BS) was chosen to estimate the stability of a yakult flavored and brown milk drink, and the effects of pectin concentration, homogenization pressure and homogenization temperature on the stability index (SI) of brown milk drink was studied by conducting Box-Behnken experiments. The optimal parameters obtained by regression analysis of response surface were as follows: pectin concentration 2.8 g/L, homogenization pressure 21 MPa and temperature 42 ℃.

Key words: back scattering, stability, milk drink, pectin, homogenization
