Abstract

In order to improve the gel properties of highland barley protein (HBP) and thus expand its application, gels were prepared by mixing the sodium alginate with HBP.The effects of different concentrations of sodium alginate on the water-holding property, gel hardness and thermal stability of HBP were investigated, and the mechanism of sodium alginate regulating the gelation of HBP was explored through the determination of the secondary and tertiary structures of HBP and the observation of its gel structure.The results showed that with the increase of sodium alginate addition, the water holding capacity and gel strength of HBP were significantly increased from 23.4% and 13.3 g to 59.4% and 33.8 g, respectively.The results of thermogravimetric analysis show that the addition of sodium alginate could improve the thermal stability of HBP, and the addition of sodium alginate had no significant effect on the secondary structure of HBP, but it would significantly decrease the surface hydrophobicity and free sulfhydryl group content of HBP by 42.3%, respectively.The surface hydrophobicity and free sulfhydryl content of HBP were significantly reduced by 42.3% and 53.3%, respectively.By measuring the molecular forces in HBP, it was found that adding sodium alginate increased the hydrogen bonding, disulfide bonding, and electrostatic interactions in the composite gel by 51.4%, 40.4%, and 50.7%, respectively.The CLSM results show that phase separation occurs after adding sodium alginate, which promotes the aggregation of protein molecules, resulting in a denser gel structure.In conclusion, sodium alginate could be used to improve the gel properties of HBP and expand the application of HBP.
