Gemili,
Yemenicioglu, and Altinkaya (2010) studied the release
of ascorbic acid and L-tyrosine from a cellulose acetatebased
film into water and found that ascorbic acid was
released faster than L-tyrosine. Garces, Nerin, Beltran,
and Roncales (2004) patented antioxidant varnishes based
on the addition of plant extracts to polyester, nitrocellulose,
acrylic and vinyl polymer solutions for food protection and
Nerın et al. (2006) reported the efficiency of these varnishes
in the stabilization of beef meat, although they also reported
a drawback derived from a collateral effect on sensory
properties of food owing to the release of highly
aromatic substances.
