In this study, the cereal beverage prepared with pine nuts
at pH 6.5 and a homogenization pressure of 19.6 MPa
showed the best physicochemical properties. These conditions produced the most stable pH in the samples after
heat treatment, and the NSI and soluble starch content,
among the samples studied, were nearly constant after 5
days storage at 4 and 258C, with the exception being the
sample stored at a temperature of 408C. As well, the
apparent viscosity of the samples homogenized at 19.6 MPa
was nearly constant, with the exception being the sample
stored at 408C, but the samples homogenized at 29.4 MPa
or without homogenization showed a prominent increase
regardless of storage temperature as the pH was increased.
Overall, among the tested processing conditions, the best
conditions for making a cereal beverage containing pine
nuts were at pH 6.5 and using a homogenization pressure of
19.6 MPa. So, these results indicate that the pH, homogenization pressure, and storage temperature are important
factors in determining the processing suitability of cereal
beverages prepared with pine nuts.
