Carbohydrate in Coffee: AOAC Method 995.13 vs a New Fast Ion Chromatography Method
1 May 2012This study tests the AOAC official method 995.13. Carbohydrates in extracts from instant coffee and green coffee beans were separated and measured by electrochemical detection with disposable Au on polytetrafluoroethylene (PTFE) working electrodes. A few proposed modifications of the official method achieved separation of two pairs of sugars, which are otherwise difficult to resolve.
