Although synthetic materials
are toxic for direct application to food products due to
crosslinking agent, which was combined with synthetic polymers,
it ensures high mechanical properties, thermal stability, and longterm
release properties (Park and others 2001; Jang and others
2005; Scarfato and others 2007). Such characteristics are suitable
for indirect application to food packaging processes like printing
and coating progress. Melamine resin in many synthetic materials
has been already investigated by many researchers. In a study, fragrant
oil was encapsulated successfully by in situ polymerization of
melamine resin (Hong and Park 1999; Hwang and others 2006).
Lee and others (2002) studied about the effect of pH and formaldehyde/
melamine molar ratio on encapsulation
