| Summary: | This study investigates the effect of oil type and concentration on the rheological and microstructural properties of plant-based emulsion gels, comparing them to animal fat tissue. Emulsion gels were formulated with soybean or coconut oil, isolated soy protein, agar, and alginic acid at varying oil concentrations (0–30 %). The structural integrity of animal fat is attributed to a fibrous network of adipocytes and collagen. In contrast, oil concentration significantly affected the gel network density, with coconut oil-based gels maintaining stable viscoelasticity, while soybean oil-based gels exhibited more fluid-like behavior. The thermal behavior of the gels was significantly influenced by the fatty acid composition of the oils, with a distinct endothermic peak observed around 20 °C for coconut oil-based gels, while no peak appeared for soybean oil-based gels. These findings highlight the potential to optimize plant-based fat analogs by controlling oil type and concentration to replicate animal fats in plant-based food products. |
