Abstract:  Based on single factor test including the ratio of water to fish,enzyme dosage,enzymatic hydrolyzing time,pH and stirring speed,oil extraction yield as evaluation index more important factors enzyme dosage,temperature and pH were studied for tai-fish oil extraction by response surface methodology. The results showed the following optimal conditionenzyme dosage 1000U/g raw material,pH 7.3,temperature 45℃.
