This study examined the effects of dietary α-tocopheryl acetate supplementation on antioxidant enzyme activities and fillet quality in commercial-size Sparus macrocephalus. Three hundred fish [main initial weight (350±12) g] were divided into three groups (E250, E500 and El000) and reared in 9 cages. The fish were fed for 8 weeks with three diets containing different levels of dietary α-tocopheryl acetate (289, 553, 1069 mg/kg). Over the experimental period, fish were fed to satiation and reached a final mean weight of (465±28) g without significant body weight difference and proximate composition difference. Fillet α-tocopherol was significantly (P〈0.05) different between groups, reaching levels of 14.2, 22.1, 30.9 pg/mg fillet for groups E250, E500 and El000, respectively. Total serum superoxide dismutase (SOD) activity increased significantly (P〈0.05) in fish fed the diets high in α-tocopheryl acetate, but serum glutathione peroxidase (GPX) activity was unaffected. In storage on ice, fillets of fish fed the diets high in α-tocopheryl acetate exhibited significantly lower (P〈0.05) levels of oxidation. These results suggested that increased dietary α-tocopheryl acetate could increase its flesh deposition, increase the activity of SOD and prevent lipid peroxidation ofSparus macrocephalus fillets in retail storage on ice. 相似文献

有一次,爸爸妈妈带我去吃夜宵。爸爸的同事点了我最喜欢吃的酸菜鱼。我夹了一块鱼肉放到嘴里。一不小心,一根鱼刺卡到了喉咙里,不上不下,我感到很难受。妈妈看见我痛苦的样子,立刻对服务生说:服务生,给我来碗米饭。服务生把米饭端来,妈妈连忙把米饭递给 相似文献

<正>1变聪明抗老化美国一项最新的研究证实,"吃鱼"除了可以变聪明,还可以"防止老化"。这项研究针对4000位65岁以上的老人进行调查,经过6年多的心智状况和饮食习惯长期追踪发现,鱼吃得越多的老人家脑力衰退得越慢;这些老年人只要一个星期至少吃一次鱼,持续一年下来,会比那些不爱吃鱼的老人家智力少衰退10%—13%,相当于年轻3—4岁。研究人员将此结果归功于鱼肉中所富含的ω—3脂肪酸,认为ω—3脂肪酸可以维持大脑的正常功能、防止老化。不管是孩童、成人或是老人,多吃鱼对于帮助脑部神经的发育和维持脑部神经健康都有极大的帮助。 相似文献

正那就跟你说说我在那些航行的途中掉落的节操吧,掉节操没什么可害臊的,能掉得百种滋味萦绕心头才叫牛掰。今天飞机上空姐发盒饭,问我:"猪肉饭?鱼肉饭?"我说:"猪肉饭。"她跟对面空姐喊:"一个猪。"我说:"我不是猪。"她说:"你到底是猪还是鱼?"我说:"我是一盒鱼。"她嘟囔着说:"明明刚才是猪,现在变成鱼了。"她把饭递给我又问我里面两位,那两个人异口同声斩钉截铁地说:"鱼肉饭!"今天飞机上空姐发盒饭,坐我里面的女孩警惕地问:"多少钱一盒"空姐非常豪爽地说:"我请客!"女孩连声"谢谢"地接了过去。等空姐推饮料车过来的时候,我对那女孩说:"我请你喝饮料。"然后抬头对空姐说:"她要 相似文献
