A hybrid RSM-PSO-ANN approach for developing cleaner-label emulsified sausages with roasted Lyophyllum decastes mushroom powder: Optimization, quality, and antioxidant activity

Abstract: The development of cleaner-label meat products with reduced fat and enhanced nutritional value is a key trend in the food industry. This study developed a hybrid RSM-PSO-ANN modeling approach to optimize emulsified sausages formulated with roasted Lyophyllum decastes mushroom powder (rLMP) for cleaner-label production. The model effectively captured the non-linear effects of fat (15–35%), rLMP (8–16%), and ice-water (30–50%) on sensory quality, with PSO-ANN showing superior prediction (R² = 0.9921) over RSM. The optimal formulation (25% fat, 12% rLMP, 40% ice water) yielded the highest sensory score. The optimized sausages exhibited improved emulsion stability (42.4% reduction in cooking loss) and enhanced texture. Furthermore, rLMP incorporation significantly increased antioxidant activity (DPPH: 37.1% to 77.2%; ABTS: 21.0% to 40.6%) and reduced lipid oxidation (65.6% lower TBARS). These findings validate rLMP as a multifunctional ingredient for developing healthier meat products, and the integrated modeling strategy provides an efficient tool for intelligent food formulation.
