Abstract
Hemp seed protein (HSP) stabilized emulsion was subjected to dynamic high-pressure microfluidization (DHPM). Gum Arabic (GA) was added to the emulsion system to prepare HSP-GA bilayer emulsion, which improved the stability of hemp seed oil (HSO). Under the DHPM treatment at 120 MPa, the particle size of HSP-GA bilayer emulsion was 260.02 nm and the zeta potential was − 25.9 mV. The interfacial adsorbed protein of the DHPM-treated emulsion increased to 37.35%. And the viscosity, the storage modulus (G'), and loss modulus (G") were increased. The HSP-GA emulsion under 120 MPa was selected to develop an oxidation kinetic model to obtain equation c=e10.56086e−3659.66658T*t+0.72, which was used to predict the POV variation of HSO within the bilayer emulsion system. The CBD retention rate was 93.54% during storage for 20 days. It can be concluded that the effective encapsulation of DHPM treatment and bilayer emulsion system is beneficial to broaden the application of hemp seeds in processing industry.
