ABSTRACT:
There is disclosed malto-dextrins having a D.E. not substantially above about 20, prepared by the enzymatic hydrolysis of oxidized starch. Syrups of the malto-dextrins are capable of remaining haze-free for long periods of time at high solids concentrations. The malto-dextrins are prepared by first liquefying a highly oxidized starch with an acid or an enzyme to a D.E. not substantially above about 7, and in a subsequent step, converting the oxidized and liquefied starch with a bacterial alpha-amylase enzyme preparation to achieve a malto-dextrin product having a D.E. not substantially above about 20.
