Abstract:
In this study, rice glutelin isolated from glutinous rice was modified by sodium tripolyphosphate at different sodium tripolyphosphate concentrations (1%, 4%, 7%). The structural, functional and rheological properties of phosphorylated rice glutelin were investigated. The results indicated that phosphorylated rice glutelin samples showed small particle size and high absolute zeta potential values. Phosphorylation reaction was occurred between -OH and -NH2 groups in rice glutelin and sodium tripolyphosphate, as confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The particle surface of phosphorylated rice glutelin samples became very rough and exhibited some small convex and concave holes. Moreover, the solubility, emulsifying and foaming properties, thermal stability and apparent viscosity of phosphorylated rice glutelin samples were significantly increased. These results suggest that the solubility, emulsification and rheological properties of rice glutelin are significantly improved after phosphorylation, which will be beneficial to expand the application of rice glutelin in food industry.

Structure and Physical Properties of Alkynes
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.
