Abstract

In this study, environmental stability, rheological properties, and structural characterization of co-stabilized emulsions using fish gelatin (FG) and tea saponin (TS) were investigated. The results demonstrated that the addition of TS significantly enhanced the emulsifying properties of FG, and the FG-TS_0.1% emulsion had the smallest particle size. TS and FG co-stabilized emulsions provided resistance to salt and high temperatures. Optical microscopy and CLSM showed that the addition of TS made FG more effectively adsorb at the oil–water interface, leading to the formation of more uniform oil droplet sizes. Additionally, the addition of TS increased the viscosity of FG emulsions, which reduced emulsion flocculation. Results of intrinsic fluorescence, FTIR, and surface hydrophobicity revealed that the addition of TS altered the secondary structure of FG, enhancing surface hydrophobicity and improving emulsification. In conclusion, the moderate addition of TS significantly enhanced the emulsification and rheological properties of FG, suggesting new potential applications for FG in various industries.

期刊介绍： The Journal of Texture Studies is a fully peer-reviewed international journal specialized in the physics, physiology, and psychology of food oral processing, with an emphasis on the food texture and structure, sensory perception and mouth-feel, food oral behaviour, food liking and preference. The journal was first published in 1969 and has been the primary source for disseminating advances in knowledge on all of the sciences that relate to food texture. In recent years, Journal of Texture Studies has expanded its coverage to a much broader range of texture research and continues to publish high quality original and innovative experimental-based (including numerical analysis and simulation) research concerned with all aspects of eating and food preference. Journal of Texture Studies welcomes research articles, research notes, reviews, discussion papers, and communications from contributors of all relevant disciplines. Some key coverage areas/topics include (but not limited to): • Physical, mechanical, and micro-structural principles of food texture • Oral physiology • Psychology and brain responses of eating and food sensory • Food texture design and modification for specific consumers • In vitro and in vivo studies of eating and swallowing • Novel technologies and methodologies for the assessment of sensory properties • Simulation and numerical analysis of eating and swallowing
