Abstract: Study on processing intermediate moisture food to screen out sodium chloride, sodium lactate, glycerol and propylene glycol as effective depressing Aw agents. Having infused beef in glycerol etc and immersed under the conditions of air temperature 40, relative humidity 64% and air speed 0.38 m/s, beef is dehydrated, and 60 min later, product with water 27.98% and Aw=0.543 is obtained. The time of dehydration is sharply shortened.

Key words: intermediate moisture food(IMF), water activity(Aw), dehydration
