| 中文摘要: |
| 研究罗非鱼下脚料蛋白酶解物（EH10K）与其锌螯合盐(CH-0)及乙醇纯化组分(CH-Ⅰ)、透析纯化组分(CH-Ⅱ)对油脂的氧化抑制效果。结果表明：EH10K 、CH-0、CH-Ⅰ及CH-Ⅱ在亚油酸体系中有明显的氧化抑制效果，且低质量浓度的CH-0、CH-Ⅰ、CH-Ⅱ的氧化抑制效果好于EH10K；EH10K、CH-0、CH-Ⅰ及CH-Ⅱ对花生油有氧化抑制的作用，且与 BHT效果相仿；EH10K、CH-0、CH-Ⅰ及CH-Ⅱ对猪油有氧化抑制的作用，且EH10K及CH-Ⅰ的效果与BHT相近。 |
| 英文摘要: |
| The effect of tilapia scraps enzymatic hydrolysates (EH10K) and its zinc chelating salts (CH-0) , ethanol and dialysis purification components of the zinc chelating salts (CH-Ⅰand CH-Ⅱ)on oxidation inhibition of oils and fats were investigated. The results demonstrated that EH10K, CH-0, CH-Ⅰand CH-Ⅱshowed good oxidation inhibitory effect in linoleic acid system, and CH-0, CH-Ⅰand CH-Ⅱwith low mass concentration had better oxidation inhibitory effect than EH10K; EH10K , CH-0, CH-Ⅰ and CH-Ⅱ showed good oxidation inhibitory effect on peanut oil and the effects were similar to that of butylated hydroxytoluene (BHT); meanwhile, EH10K, CH-0, CH-Ⅰ and CH-Ⅱ also showed good oxidation inhibitory effect on lard and the oxidation inhibitory effects of EH10K and CH-Ⅰwere close to that of BHT. |
