Attempts were made to fix acetaldehyde on base materials, which were selected from carbohydrates, by freeze drying. More acetaldehyde was fixed, in general, on combined base materials than single base materials, and mannitol+lactose were the best among the combined base materials tested. But the combination of mannitol and maltodextrin appeared to be more economical for the mass production. Loss of acetaldehyde during freeze drying was decreased as the concentration of the combined base material was increased, and it reached minimum at 40% of the base material. As dryer chamber pressure was reduced, loss of acetaldehyde during drying decreased.
