Polysaccharide-based foam template aerogels are recognized as superior substrates for oleogels and can serve as effective alternatives to animal fats.In this study, methylcellulose was selected as the raw material, and a combination of high-speed dispersion, foaming, and freeze-drying technology was employed for the preparation of these aerogels.The effects of methylcellulose viscosity and concentration on the characteristics of polysaccharide solutions and foams were systematically investigated.Furthermore, scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis were utilized to comprehensively characterize the properties of the aerogels.The results indicated that the expansion rate of low-viscosity (450 mPa·s) methylcellulose aqueous solutions increased with higher concentrations, whereas the expansion rate of high-viscosity (40 000 mPa·s and 100 000 mPa·s) methylcellulose aqueous solutions decreased.Compared to methylcellulose aqueous foams with viscosities of 450 mPa·s and 100 000 mPa·s, the 40 000 mPa·s methylcellulose aqueous foam exhibited superior stability, with no layering observed after 4 h of room temperature storage.Additionally, the concentration of methylcellulose significantly influenced the properties of the aerogels.Specifically, the internal porous structure of the 16 g/L methylcellulose (40 000 mPa·s) aerogel was more uniform and dense, with a relatively homogeneous pore distribution, smaller average pore size, and enhanced thermal stability, demonstrating excellent overall performance and suitability as a biological oleogel template.This study provides valuable technical insights for the development of green and safe alternatives to animal fats.
