Sugar beet molasses

Molasses made from sugar beet differs from sugarcane molasses. Only the syrup remaining from the final crystallization stage is referred to as molasses.

preservative, helping to kill off moulds and bacteria. Sulfur dioxide is also used as a bleaching agent to help lighten the colour of molasses. Most brands have abandoned the use of sulfur dioxide in molasses because untreated molasses already has a relatively stable natural shelf life. Poor flavour and the trace toxicity of low doses of sulfur dioxide are also factors that have led to the removal of its use.
