Sample stability needs to be evaluated  for extraction time (depending on  solution) and also overall shelf life after  extraction due to enzymes and  microbial activities in these matrices.  

A paragraph was added to Section 7.  “Method data packages must include  relevant data regarding interferences  and instabilities, such as listed in Table  2.   Data packages must include data to  demonstrate that the sugar  composition in the extract is a  representation of the true sugar  composition in the food product and  assess the stability of extracts over the  duration of the test.“

No change but an ERP should get some  guidance when judging a method to be  in accordance to this SMPR. Otherwise  an endless discussion would occur  which is not due to a non‐validated  method but to an unclear SMPR. If a method developer submits a  method for sucrose‐glucose‐fructose  quantification in bread and Cookies, it is  up to a method user if this "narrower  matrix range" is appropriate or not.  I am concerned that there is no section  for reference materials in this SMPR.

1) If the submitted method is applicable  only to a subset of foods or feeds, that  information must be clearly described  to allow ERP deliberation if the method  satisfies Stakeholder needs. 2) As written, the minimum number of  sugars that must be measured by a  method is six  regardless of the  "narrower matrix scope" clause. Recommend no change to SMPR . This was an oversight by the working  group.  A reference material section was  added as Section 8 and includes  example Reference Materials Appendix  F in OMA.
