Sample containing starch are digested using amylase and AMG under controlled conditions (simulating human digestion). Aliquots are pulled at 20 minutes and 120 minutes, and the enzyme reaction is stopped by boiling. Glucose in both fractions is measured with GOPOD (glucose oxidase – peroxidase) on a spectrophotometer and rapidly- and slowly-digestible starch is calculated.
Moisture and Total starch testing will be run as part of completing the Englyst test.
The purpose of this method is to screen food and ingredients for the purpose of optimizing a lower Glycemic Response. A human study is helpful once a low-glycemic formula is optimized for the most extensive support of claims.
