AFFINATION
Treatment of raw sugar crystals to remove the outer layer of molasses. Sugar manufacturers mix sugar crystals with concentrated syrup and then send the mixture of liquid and crystals through a centrifuge to separate them. Sugar that has been through the affination process is called affinated sugar.
AGGLOMERATION
Sticking together of two or more sugar crystals as they go through the centrifuge and the drying process.
ASH CONTENT
Solid residue remaining after burning a sugar sample in the presence of oxygen. Carbonated ash is the residue remaining after burning a sample at 650 'C. Sulphated ash is the residue remaining after burning a sample pre-treated with sulphuric acid at 650 'C. Sometimes determined indirectly by measuring electrical conductivity of the product in solution (see conductivity ash).
