Other important properties of levan are non-toxic and ocular non-irritant. Levan is fairly heat stable with a melting point temperature of 225 °C (Ullrich, 2009) and is strictly non reducing, not hydrolysed by the action of amylases as well as invertases secreted by the yeast (Gupta et al., 2011) These remarkable properties of levan made it superior in many commercial industrial sectors as standard film forming agent and as a stable polymer.
