a high antioxidant activity
of green tea catechins in beef and chicken meat. In another
study, O’Sullivan, Lynch, Lynch, Buckley, and Kerry (2004)
evaluated the effect of several natural extracts on oxidative
stability of chicken nuggets during refrigerated (4 C) storage.
Nuggets were supplemented with rosemary extract (at 1000 ppm), sage extract (at 1000 ppm), or tea catechins (at
100 ppm). Their results indicated that the addition of natural
extracts, including tea catechins, reduced lipid oxidation in
chicken nuggets both in the presence and absence of salt.
However, when sodium tripolyphosphate (STPP) was incorporated
into the same product system, the efficacy of natural extracts
was significantly reduced.
