Abstract:

Response surface methodology (RSM) was employed to optimize the supercritical CO2 extraction conditions for volatile components from sauced duck. The effects of extraction pressure, temperature and duration on the ratio between volatile components and total extract were investigated. Results indicated that the ratio between volatile components and total extract was decreased with the increase of extraction temperature and pressure, while the ratio exhibited an initial increase and a final decrease with the increase of extraction time. The optimal extraction pressure, extraction temperature and extraction time were determined to be 11 MPa, 41 ℃ and 60 min, respectively. The ratio between volatile components and total extract was up to 83.45% under these optimal extraction conditions. A total of 60 volatile compounds were identified in extract by GC-MS. Most of these volatile compounds were lipid oxidation and Maillard-reaction products, such as aldehydes, ketones, aliphatic hydrocarbons, aromatic hydrocarbons, esters and heterocyclic compounds.

Key words: sauced suck, supercritical carbon dioxide, volatile components
