LAS VEGAS — Members of the Institute of Food Technologist presented Advantix Systems, Ampac, Ecolab and Glanbia Nutritionals with the 2012 IFT Food Expo Innovation Awards at the I.F.T.’s annual meeting and food expo being held this week in Las Vegas.

Advantix Systems, Miami, was given the award for its liquid desiccant dehumidification and cooling technology that reduces energy use by 50%.
