Results of Carroll et al. (2006) and Heguy et al.
(2006) were established using composite gels prepared
at 120 °C. This temperature allowed preparing shelfstable
composites; however, it has been established
that whey protein-based emulsion gels (the composites)
can be successfully prepared at much lower temperatures
of 85–90 °C (Mor et al., 1999; Mor-
Rosenberg et al., 2004). Thus far, only the efficacy of
composite gels at 120 °C has been reported. The
objective of this study was to investigate the extent to
which lipids included in WPI-based composite gels
prepared at 85 °C are protected against ruminal biohydrogenation
in lactating goats.
