| 摘 要： | 旨在研究光照对油脂抗氧化剂抗氧化效果的影响。分别研究在254、365 nm波长光照射下,猪油中添加丁基羟基茴香醚(BHA)、2,6-二叔丁基-4-甲基苯酚(BHT)、特丁基对苯二酚(TBHQ)、没食子酸丙酯(PG)对其过氧化值、酸价、丙二醛值、共轭二烯类值、共轭三烯类值的影响。结果表明,与空白相比,在254 nm光照下,4种抗氧化剂抑制猪油过氧化值、酸价、丙二醛值、共轭二烯类值、共轭三烯类值的效果差异不显著(p>0.05);在365 nm光照下,BHA、BHT、PG抑制猪油过氧化值、酸价、共轭二烯类值、共轭三烯类值效果差异性不显著(p>0.05),抑制丙二醛效果差异极显著(p<0.01)。TBHQ抑制猪油酸价、共轭三烯类值效果差异不显著(p>0.05),抑制过氧化值、共轭二烯类值差异显著(p<0.05),抑制丙二醛效果差异性极显著(p<0.01)。由此说明,在254、365 nm光照射下,BHA、BHT、PG基本没有抗氧化效果,TBHQ的效果也不够理想。

| Abstract: | To investigate the antioxidant effects of 4 antioxidants on oil under UV light. The effect of acid value,peroxide,malondialdehyde-value,conjugated diene and conjugated trienes compounds in lard by using butylated hydroxyanisole(BHA),2,6-Di-tert-butyl-4-methylphenol(BHT),tert-Butylhydroquinone(TBHQ)and Propyl gallate(PG)under 254,365 nm were studied. The results showed that,compared with the blank test sample,the differences of acid value,peroxide,malondialdehyde-value,conjugated diene and conjugated trienes compounds at 254 nm light between BHA,BHT,PG were not significant(p>0.05).The differences of acid value,peroxide,conjugated diene and conjugated trienes compounds at 365 nm light between 4 antioxidants and blank test sample were not significant(p>0.05),difference of malondialdehyde value was extremely significant(p<0.01).As for acid value,the differences of conjugated diene and conjugated trienes compounds between TBHQ and blank test sample were not significant(p>0.05),the peroxide and conjugated trienes were significant(p<0.05),difference of malondialdehyde value was extremely significant(p<0.01). It was concluded that BHA,BHT and PG had no antioxidant effect under 254,365 nm UV Light irradiation,and TBHQ was also not ideal. |
