Effect of Phosphorylation on Aqueous Enzymatic Extraction of Soybean Oil as Analyzed by FTIR

Abstract

Abstract: As an approach to improving protein solubility, phosphorylation was introduced into the aqueous enzymatic extraction of soybean oil to increase total oil yield. The relationship between the secondary structure of soybean proteins modified for different time periods and total oil yield was explored by FTIR spectroscopy. The results showed a negative correlation between total oil yield and β-sheet content (r = －0.949, P = 0.004) or random coil content (r = －0.873, P = 0.023), as well as a positive correlation between total oil yield and α-helix content (r = 0.962, P = 0.002) or β-turn content (r = 0.912, P = 0.011).

Key words: soybean, phosphorylation, FTIR, aqueous enzymatic extraction
