Application:
1) Sodium acetate is a mordant in dyeing. Other applications are in photography, as an additive to food, in purification of glucose, in preservation of meat, in tanning, and as a dehydrating agent. In analytical chemistry it is used to prepare buffer solution.
2) Sodium acetate can be used to preserve processed meats and it is often used in combination with other acid based preservatives like lactates and propionates. The typical inclusion level is 0.2 to 0.5%. Sodium acetate is also used in salad dressings and ready-to-eat meals.
