      hi to al... i think v can use the chromotographic technique to separate the flavor compounds in solution form .. flavor compounds r organic and chromotography is the technique of separating organic compounds mixed in solution form... separation takes place by virtue of their diffusion through the adsorbin material or the statioary phase.. there r many types of chromotography - paper, column, even a piece of chalk...
      The technique depends on the differential distribution of solute between the mobile and stationary phases. the mixture solution diffuses into the adsorbin material with help of a solvent say mobile phase...
      since flavors r al organic material, i think that this method wud b suitable but can b identified only if the organic compounds are coloured... in case of colourless compounds may be v can use some chemical identification test after the separation.. . but iam not sure with this... suggestions & corrections r welcomed...
