A low D.E. starch hydrolysate having a D.E. not substantially above about 20, a relatively narrow molecular weight distribution such that its weight average molecular weight to its number average molecular weight ratio of Mw/Mn is less than about 20 and said hydrolysate being further characterized as containing less than about 20% by weight, dry basis, of starch oligosaccharides having a degree of polymerization greater than about 200. The low D.E. starch hydrolysates are prepared by enzymatically hydrolyzing starch dextrins having a degree of branching of at least about 7%. The low D.E. starch hydrolysates are resistant to the formation of haze at high solids and they exhibit reduced enzyme susceptability.

Low D.E. starch hydrolysates of improved stability prepared by enzymatic

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.
