The liquefaction of pre-gelatinized starch was studied with various analytical techniques to determine the effects of starch molecular weight, granule structure, granule size, and mechanical depolymerization. Also, improvements were made in the chromatographic system used to characterize starch hydrolysates. Progress is reported on protein removal. The effects of pH, temperature, and ionic strength were examined for the removal of protein from a syrup stream by adsorption on a phenolic resin. Buffered systems, which maintain more stable pH values, were also examined. Mathematical modeling of the results is in progress. The pilot plant facility is complete and in operation. Starch streams containing 1% protein are being produced by the protein extraction process.
