| Abstract: | Camellia Seed shell was used as a raw material and the flavonoids were extracted from the shell assisted by ultrasonic technology.The optimum technical conditions were confirmed by single factor and orthogonal experiment.The total flavonoids antioxidant ability in lard was evaluated.The result showed that the optimized conditions were ethanol concentration 40%(v/v),temperature 65 ℃,ratio of solid-liquid 1∶ 30(w/v),ultrasonic power 480 W,extracting time 30 min,the extraction yield was 5.02%,the amount of 0.15%(w/w) flavonoids had better antioxidant ability in lard. |
