Homogenization is a unit operation that can be incorporated in citrus juice manufacturing to improve
chemical and physical characteristics relevant for use in subsequent processing operations. The aim of
this study was to evaluate the effect of different homogenization pressures on suspended solids and antiradical
activity in mandarin low pulp juice (LPJ) and to understand their influence on a posterior vacuum
impregnation operation. We found the pressure treatments applied to LPJ do not have negative effects on
antiradical activity or functional compounds in the juice. In the vacuum impregnation study we found
that more LPJ was introduced into the structural matrix of apples when homogenized at higher pressures
and therefore more functional compounds may be introduced due to pulp stability and particle size
reduction.
