This study utilized immature peach powder (IPP) as a stabilizer to construct a food-grade Pickering emulsion gel system. The effects of IPP concentration (w) and oil phase volume fraction (φ) on its structure and properties were investigated, with subsequent application as a butter substitute in cake production. Results indicated that IPP exhibited diverse morphologies and broad size distribution (5-96 μm), with a three-phase contact angle of 75.62°±1.27°, demonstrating potential for stabilizing Pickering emulsions. The O/W-type Pickering emulsion gels with φ ≥ 60% were achieved at w ≥ 3%. Droplet size was negatively correlated with w and positively correlated with φ, while gel strength showed positive correlations with both parameters. All emulsion gels displayed solid-like viscoelastic behavior and pseudoplasticity in rheological tests. The gel prepared at w=4% and φ=60% successfully partially replaced butter in cakes while maintaining normal texture and structure. These findings can promote the application of IPP in foods.
