Proposed Fitness for Purpose for Sugars in Animal Feed, Pet Food, and Human Food ▪ Individually measure free fructose, glucose, sucrose, maltose, lactose, and galactose found in ingredients and foods consumed by animals, pets, and humans. The analytical method must account for common interferences, such as sugar alcohols in these matrices.

Dietary Fructans ▪ Dietary fructan is water-soluble class encompassing oligosaccharide and polysaccharide carbohydrates ▪ Comprised predominantly of DP>3 fructose molecules and containing no more than one-third glucose molecules. ▪ This polymer of fructose molecules may or may not contain a terminal glucose molecule, and includes inulin and FOS. ▪ Fructans are not digested by enzymes in the small intestine but can be fermented in the large intestine. ▪ Nutritionally and compositionally distinct from other carbohydrates such as sugars, starch, and other forms of dietary fiber. ▪ Primary sources of fructan are cool season grasses, chicory, and onions.
