概括

天然抗氧化剂 (NAOXs) 增强了料的稳定性,并通过减少脂质过氧化来改善大西洋的氧化保护. 这项研究追踪了通过料生产和进入鱼类组织中的多,证实了它们对可持续水产养殖的有效性和稳定性.

科学领域:

水产养殖营养水产养殖营养
鱼类生理学鱼类生理学
食品化学食品化学

背景情况:

合成抗氧化剂如乙氧化,BHT和BHA面临监管限制,推动了对水产料中天然替代品的需求.
天然抗氧化剂 (NAOXs),特别是多,在防止料氧化和减少鱼类氧化应激方面表现有前途.
评估NAOX在料加工和鱼类中的稳定性和生物影响对于其采用至关重要.

研究的目的:

评估四种天然多 (NP) 在水产料生产和加工过程中的稳定性.
为了确定NAOX补充剂对大西洋鱼的氧化状态和关键生理参数的影响.
通过饮食摄入后,追踪鱼类组织 (肝脏和肌肉) 中特定NP的命运.

主要方法:

一种富含四种天然多的植物性成分被纳入标准鱼料中.
在各种料生产阶段 (原料,混合,挤出,干燥,储存) 使用LC-MS量化聚醇.
在大西洋鱼化后,人们在100天的时间内食多丰富成分的不同水平的食,并评估了氧化标志物和生理参数.

主要成果:

纳奥克斯补充剂改善了料的氧化稳定性,由增加的阿斯塔克桑,多科菲醇和减少的TBARS证明.
饮食NAOX没有影响鱼生长,器官指数,白内障形成或片颜色.
在鱼类中观察到恶性甲 (MDA) 和肝脏谷氨 (GSH) 的显著降低,表明抗氧化剂保护得到了增强.
在4个追踪的NP中,有3个被检测到在鱼组织中,主要是肝脏,尽管挤出过程中损失很大.

结论:

天然抗氧化剂有效地提高了料的稳定性,并提高了大西洋鱼的氧化弹性.
聚醇可以通过水产养殖料生产链追溯,其概况反映了原始成分.
在水产养殖中,NAOX是改善料质量和鱼类健康的可持续和有效战略.

Radical Autoxidation

Radical Autoxidation

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Osmoregulation in Fishes

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?
