Saccharification of explosively dried corn.
Very rapid or explosive drying of grains such as corn leads to obvious physical changes in the macrostructure of the grain kernel, probable alteration in starch molecular structure, and reduction in starch average molecular weight. These changes lead to greater susceptibility to attack by liquefying and saccharifying enzymes. Rates of formation of nonreducing and reducing sugars by liquefying and saccharifying enzymes applied to explosively dried and milled yellow dent corn and small-kernel flint corn were 3.3-10.6 times greater than rates for the normally milled grains. The enzymatic conversion of explosively dried flint corn containing absorbed ethyl alcohol, as would be the case if it had been used as an adsorbent to dewater aqueous ethyl alcohol, was not significantly different from that of ethyl-alcohol-free flint corn.
