柚皮及提取液抑制猪油氧化作用的研究

研究了柚皮干粉及鲜柚皮提取液（CPE）对猪油自动氧化作用的影响。结果表明：柚皮粉及柚皮提取液（CPE）有很强的抗猪自动氧化的能力，CPE的作用能力强于柚皮粉，0．8％的柚皮乙醇提液（CPE1），2％的柚皮正丁醇提液（CPE2），乙醇乙酯提液（CPE3）的抗氧化能力与0．02％的BHT相当；且添加高达16％的CPE其抗氧化能力表现为明显增强并且未出现促氧现象。

A STUDY ON THE INHIBITING EFFECT OF POMELO PEEL EXTRACT ON AUTOXIDATION IN LARD

In the experiment reported in this paper, both pomelo ( Citrus grandis) peel powder (PPP) and pomelo peel extract (PPE) were effective in inhibiting autoxidation in lard. The inhibiting effect of PPE was stronger than that of PPP. The anti-oxidation of PPE with ethanol at 0.8%,PPE with n-butyl alcohol at 2% or PPE with ethyl acetate at 2% was similar to that of BHT (0.02%),The addition of PPE at a concentration as hight as 16% did not show any speeding-up of lard oxidation.
