also potential antioxidants in meat products. Pen˜ a-Ramos
and Xiong (2003) evaluated the antioxidant activity of
selected whey hydrolysates in cooked meat pork patties.
The results indicated that at an application level of 2% the
whey protein isolates and their hydrolytic products not
only reduced the cooking loss but also suppressed lipid
oxidation in cooked pork patties during refrigerated
storage. Notably, hydrolysis with protamex improved the
capability of whey protein to inhibit early-stage lipid
oxidation (formation of hydroperoxides or conjugated
dienes) as well as to retard propagation of the oxidation
process (degradation of hydroperoxides leading to TBARS
formation). Thus, partially hydrolyzed whey proteins seem
to be particularly attractive ingredients for quality improvement
