Sugar SMPR Key Points

• Method data packages must include performance data  covering the method claimed matrices. A useful tool can be  found in food pyramid concept described in Annex F of  Appendix F the AOAC Official Methods of Analysis. Matrix  variations in non‐sugar carbohydrate and moisture content  must be investigated and data provided.  For example, using  the food pyramid in sector 7, a matrix may be either high in  sugar or high in non‐sugar carbohydrates (e.g., starch, sugar  alcohols), each of which may affect method performance.   • Method data packages must include relevant data regarding  interferences and instabilities.

There should be significant evaluation  of the method for finished pet foods  before it is accepted, to avoid significant  problems with interferants.  Otherwise,  there are quite a few common  ingredients in pet food which would  cause interference. Can you please provide clarification in  the SMPR if the method must be  written to encompass all sugars in one?

SMPR states “Method data packages  must include relevant data regarding  interferences and instabilities”, and  includes a list of classes of potential  interents with clear examples.   Recommend no change to SMPR . The SMPR  implies a single method to  measure the at least six free sugars.   The working group agreed to a  minimum set of six free sugars.  Recommend no change to SMPR . The minimum number of sugars is  clearly defined" . . . minimally: fructose,  galactose, glucose,sucrose, maltose,   and lactose . . .“. Recommend no change  to SMPR .

SMPR should state somewhere that  submission of methods that only cover  a subgroup of sugars in selected  matrices are also of interest.
