ABSTRACT:
The invention relates to an improved process for the synthesis of sugar esters carried out in a substantially anhydrous system and in the presence of an organic acid chloride. Any of the known available sugars may be used and in particular hydrolyzate sugars derived from starch are effectively employed in accordance with the present invention to produce sugar esters having superior emulsifying characteristics for use as an ingredient in food products for human consumption.
