Introduction
During processing, storage, and display,
meat and poultry products are subjected to
harsh environments that are ideal for
oxidation, thus reducing overall product
appeal. One way to combat these negative
aspects is to add natural herbal flavorings
and/or antioxidants (AO). Recent reported
health issues surrounding synthetics have
increased the interests of consumers to seek
out products containing natural ingredients.
