Effect of maleylation on physicochemical and functional properties of rapeseed protein isolate

Abstract: Influence of maleylation on the physicochemical and functional properties of rapeseed protein isolate was studied. Acylation increased whiteness value and dissociation of proteins, but reduced free sulfhydryl and disulfide content (p < 0.05). Intrinsic fluorescence emission and FTIR spectra revealed distinct perturbations in maleylated proteins' tertiary and secondary conformations. Increase in surface hydrophobicity, foaming capacity, emulsion stability, protein surface load at oil-water interface and decreas… Show more

“…B, SRPI films exhibited lower values of ΔE, which means SRPI films are more similar to the white standard plate. These results are in agreement with the findings of Purkayastha et al (), when the films were brought into application, light color can make a good commercial effect.…”

“…Compared to the RPI film, the 5% SRPI film had an increased content of β‐sheet from 39.9% to 49.2%, whereas those of α‐helix, β‐turn, and the random coil decreased from 24.8%, 21.1%, and 14.2% to 21.3%, 18.8%, and 10.8%, respectively. These results are partly similar to the results determined by Purkayastha et al (), but are opposite to the results obtained by Zhao et al (). It might be stated that intermolecular hydrogen‐bonding interactions between β‐sheets may act as the major junction zones and thus stabilize the film network, as the content of the β‐sheet is about a half of the secondary structure of protein.…”
