1 Scope

This standard specifies the honey fructose syrup, maltose syrup, maltose syrup different measurement method, caramel syrup and other starch syrup. This standard applies to the determination of starch in honey syrup. The standard detection limit. 5% starch syrup. Principle 2 Honey does not contain pentasaccharide (DP5) above oligosaccharide, and a variety starch syrup inclusive pentasaccharide (DP5) or more oligosaccharides, using a gel volume Removal of sample exclusion of fructose, glucose, directly through the anion-exchange oligosaccharides enriched chromatography - electrochemical detector, the pentasaccharide Presence (DP5) above is determined as an indicator of honey oligosaccharides in starch syrup.
