Background: Fructans

Currently two AOAC methods for fructan in foods (999.03 and 997.08); however, not fit-for-purpose for animal food. • Acid hydrolysis is more effective than use of inulinase (effective on inulin) for analysis of fructans in cool season grasses. • Hydrolysis of current methods may be modified for use in animal food

Fructans SMPR Key Points

Applicability • Measure total dietary fructan, such as inulin, levan, branched fructans, agavins (agave fructans) and fructooligosaccharides, in animal feed, pet food, and the corresponding ingredients. The method must be capable of distinguishing this compound from interfering compounds such free glucose, fructose, sucrose and other polysaccharides.
