Overconsumption of fat-rich foods has led to a significant increase in the incidence of chronic diseases in humans. With the increased pursuit of a healthy lifestyle, low-fat products are gradually developing. In this study, egg white protein microparticle (EWPM) was used as a fat mimetic in low-fat mayonnaise, as well as xanthan gum (XG) and gum arabic (GA) were used as texture and rheology modifiers. The results showed that XG and GA had a synergistic effect on modifying viscosity and recovery of EWPMstructured low-fat mayonnaise. The addition of XG could effectively increase the viscosity of low-fat system, due to the electrostatic binding with EWPM and the intermolecular entanglement. The incorporation of XG with GA could effectively intervene intermolecular interactions to improve recovery, verified by the decreased particle size and weakened electrostatic binding. The results would provide practical guidance for the development of high-protein and low-fat nutritious mayonnaise.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
