Study on Affecting Factors in the Reaction between Protein and Polyphenols

Abstract

Abstract: The complex reaction between protein and polyphenols was studied on the basis of content variations of dissociated protein.The assay was made on the absorbency at the wavelengh of 595nm.The test was designed to study the affecting factors of temperature,pH value,ethanol and protein-polyphenol ratio.The results showed that when the conditions were:40℃,pH 3.5,ethanol concentration 6%and casein-TA concentration ratios 5∶1,the amount of the protein-polyphenol complex compounds reached the optimum production.

Key words: complex reaction, pH value, ethanol concentration, protein-polyphenol ratio, temperature
