Abstract: The presence of a sufficient amount of a calcium complexing agent prevents the gelling of corn steep liquor.

Abstract: The "livering" or gelling of corn steep liquor or liquid products containing corn steep liquor is prevented or reversed by the addition of an effective amount of a calcium complexing agent, preferably at a pH of less than about 3.8.

Abstract: Phytate-containing proteinaceous materials are treated with trivalent aluminum to alter the physical, chemical, metabolic, functional and nutritional values of the protein. Protein derived from phytate-containing seed materials treated with trivalent aluminum possess improved solvent solubility, protease digestability, reduced thermophiles and trypsin inhibition reduction, low viscosity, trace mineral bioavailability, etc. without requiring phytate or phytic acid removal. The aluminum treatment may be conducted at numerous protein manufacturing stages with a wide variety of different materials. Phytate-containing proteins may be effectively extracted at acid pH levels in the presence of trivalent aluminum without sacrificing recoverable protein yields.

Abstract: A dye binding reagent for protein assay comprises Coomassie Brilliant Blue G-250 and an acid having a pKa of from 1 to 2. Upon addition of the reagent to a protein-containing solution, the attendant color change can be spectrophotometrically measured to quantitate even micrograms of protein. Furthermore, the reagent is applicable to a wide range of proteins and requires only about 2 minutes for measurement. Addition of an alcohol such as ethanol to the reagent further improves sensitivity.
