Abstract:
A method for preparing a maltose product, comprising:treating a starch with an enzyme that consists essentially of a beta amylase enzyme under conditions suitable to form a product mixture that includes maltose and at least one higher molecular weight carbohydrate, said starch containing amylose in an amount of 10% or greater, whereby at least a portion of said amylose becomes retrograded; allowing at least a portion of said retrograded amylose to crystallize from said product mixture; separating the crystallized retrograded amylose from said mixture leaving a remaining mixture containing maltose and a higher molecular weight carbohydrate having a dextrose equivalent value of less than 5; and recovering a maltose product from said remaining mixture thereby leaving a second fraction, said maltose product containing relatively more maltose than said second fraction.
