Glycerin in dog food

Glycerin, glycerine, glycerol and E422 all refer to the compound, propane-1,2,3-triol. It is found throughout nature as an essential part of tri-glyceride fats. It is not, however, found on its own which has led some more ardent natural feeding advocates to label isolated glycerin as 'unnatural'. Pure glycerin is non-toxic and is generally regarded as safe. It is generally produced as a byproduct of soap manufacture and it has found a wide range of applications in the food and cosmetic industries. It is regularly found in pet foods (especially treats) as a humectant - that is it helps keep foods moist without allowing the moisture to speed up the food's decomposition. It also has a sweet taste which makes any foods it is added to more appealing to dogs.
