 2 3.   DEFINITIONS  
 High Fructose Syrup: is a product produced from the hydrolysis of 
starch by enzyme such as  amylase or glucoamylase or by acid to 
form a glucose sugar solution, and then partialy Isomerizing  the 
glucose solution to fructose with glucose Isomerase or with alkali 
solution, to form a mixture solution of fructose and glucose, in 
which the fructose content should be 42% or 55% as dry basis.
