复合天然抗氧化剂对鳊脂肪的抗氧化效果

Effect of complex natural antioxidant on Parabramis pekinensis lipid

为了获得一种能够有效抑制鳊(Parabramis pekinensis)脂肪氧化的复合天然抗氧化剂,试验中将VE、茶多酚、虾青素、迷迭香提取物、葡萄籽提取物、人参提取物和芦丁提取物进行复合,并研究复合天然抗氧化剂对鳊脂肪氧化的抑制作用。结果表明,在组分筛选试验设计的8组复合天然抗氧化剂中,迷迭香提取物、人参提取物和VE组成的复合天然抗氧化剂具有较好的抗氧化效果(下文将迷迭香提取物、人参提取物和VE组成的复合天然抗氧化剂简称为目标抗氧化剂);试验对目标抗氧化剂的抗氧化性能进行验证,结果表明目标抗氧化剂的抗氧化效果显著优于组分筛选试验中的其他组合(P<0.05),并将目标抗氧化剂与人工合成抗氧化剂(BHA、BHT、TBHQ)进行比较,结果表明目标抗氧化剂与这3种人工合成抗氧化剂抗氧化效果无显著差异(P>0.05)。

The purpose of this study was to discover some complex natural antioxidant controlling oxidation of Parabramis pekinensis lipid. In this paper,VE,tea polyphenols,astaxanthin,rosemary extract,grape seed extract,ginseng extract and rutin extract were complex to restrain lipid oxidation of P. pekinensis. The experiments showed that rosemary extract,ginseng extract and VEcomplex had better effect of antioxidation on P. pekinensis lipid（ P〈0. 05）. The contrast experiments proved the complex natural antioxidant had equivalent antioxidation to BHA,BHT and TBHQ（ P〉0. 05）.
