In this paper we dealt with processing of sausage using duck mechanically deboned meat(duck-MDM). The results may be summarized as follows : 1) after semi-thawing of freezing duck-MDM at $25^{\circ}C$ for 3 hours and cutting as thin, 2) alkali washing at low temperature for 4 hours by 0.2% NaHCO$_3$and 0.15% NaCl, 3) curing at low temperature for 4 hours, 4) after washing and dehydrating(moisture 80%), 5) grinding at low temperature for 55 minutes by silent cutter such as 1st grinding for 10 minutes added only dehydrated meat, 2rd grinding for 30 minutes added salt in 1st grinded meat and 3rd grinding for 15 minutes added other additives, 6) after quick casing in PVDC film and heating at 9$0^{\circ}C$ for 80 minutes, 7) cooling to below room temperature. The additives added at 3rd grinding process were Polymix-CA(0.3%), Polymix-CS(0.3%), polyphosphate(0.3%), sugar(4.2%), potato starch(8.0%), pyre-phosphates(0.3%), isolated soy protein(7.0%), MSG(0.2%), onion powder(0.5%), garlic powder(0.1%), nutmeg (1.5%), potassium sorbate(<0.1%), food red no.40(0.0075%), egg albumin(7.0%) and gluten(3.0%).

In this study, by using Landrock method modified by Yokozeki (1973) and Koizumi (1980), water activity ($a_w$) of various model preparations of Kamaboko was measured and ability of lowering $a_w$ of humectants added such as sodium chloride, sugars and polyols was discussed. The results were as follows : 1 The effect of sodium chloride on lowering aw was the highest among all of examined. When $4\%$ sodium chloride as humectant was added to the model Kamaboko, the $a_w$ was reduced to 0.94 or below. 2. Among the sugars, glucose was so effective that it lowered $a_w$ to 0.96 by adding $10\%$, but it would cause browning reaction on the Kamaboko surface. 3. Glycerin was the most effective among the polyols. When it was added by $10\%$, the $a_w$ of Kamaboko was reduced to 0.95. 4. It was more effective to decrease $a_w$ to lower moisture content of model Kamaboko.
