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
