It was found by an orthogonal test design that LTP had cooperative antioxidation with gallic acid (GA) and citric (CA). The POV value inhibition of 100ppmLTP+50ppmGA+50ppmCA,100ppmmLTP,100ppm TBHQ was respectively 90.6%,65.7% and 92.9% .

• 采用正交设计 ；发现没食子酸、柠檬酸和LTP具有协同抗氧化作用 ；5 0ppm没食子酸 +5 0 ppm柠檬酸 +10 0 ppmLTP、10 0ppmLTP、10 0 ppmTBHQ对油脂过氧化值抑制率分别为 90 .；6%25、6 5
