Raw Sugar is made in large refineries by crushing cane sugar or beet root to obtain juice and boiling this juice to remove water and processing the juice so obtained to make unrefined raw sugar.
White sugar is sugar which has been refined and washed so that it has a white appearance and no molasses flavour. It contains 99.9% sucrose. It is normally consumed in households and being relatively neutral in flavour, it is used as an ingredient in various edible processed foods and beverages.
Generally cane sugar is produced by tropical countries and the beet sugar by the cold/European areas.
ICUMSA – International Commission for Uniform Methods of Sugar Analysis
ICUMSA is a world-wide body which brings together the activities of the National Committees for Sugar Analysis in more than thirty member countries.
An ICUMSA rating is an international unit for expressing the purity of the sugar in solution, and is directly related to the colour of the sugar. Be aware that there are different types of ICUMSA units. For Brazilian sugar, the lower the ICUMSA figure the whiter the sugar. However, this is not the case in the E.U. for some unknown reason, which has been the subject of much discussion.
