Optimisation of Goose oil extraction process by response surface methodology.

ABSTRACT: This study aimed to optimize the ultrasonic-assisted extraction process of goose fat using response surface methodology (RSM) with a four-factor, three-level experimental design to obtain high-quality goose fat that meets national standards. The optimal extraction conditions were determined as follows: ultrasonic power 558 W, extraction time 20 min 36 s, solid-to-liquid ratio 1:5, and temperature 29 °C, achieving an average extraction yield of 78.78%. Verification experiments under these conditions (n = 3) yielded a goose fat recovery rate of 80.22 ± 0.22% (relative error: 0.98%). Scaling up the process by 100-fold (n = 3) resulted in a recovery rate of 81.12 ± 0.22% (relative error: 2.97%). The extracted goose fat exhibited an acid value of 1.112 ± 0.21 mg/g and a peroxide value of 0.031
