Abstract

Salinity is a significant environmental component that affects the physiological state of aquatic species. This study aimed to investigate whether water salinity had an impact on the biochemical properties and meat quality of adult Aplodinotus grunniens during temporary rearing of 7 days. Salinity caused increased osmotic pressure and antioxidant enzyme activities of Aplodinotus grunniens, which were attributed to the increase in the content of alanine and glutamate. It raised the hardness and shear force with an increase in salinity, leading to an increase in water-holding capacity. Salinity enhanced the DHA ratio with a decrease in the atherosclerotic index and thrombosis index. Combined with the increase in flavor amino acids and nucleotides, salinity enhanced the umami taste of Aplodinotus grunniens. These findings suggest that temporary rearing in salinity might be a practical approach to improving the meat quality of adult Aplodinotus grunniens.

不同盐度对淡水成鱼暂养期间生化特性和肉质的影响
盐度是影响水生物种生理状态的重要环境因素。本研究旨在探讨盐度对暂养 7 天的草鱼成鱼的生化特性和肉质是否有影响。盐度导致草鱼的渗透压和抗氧化酶活性升高,这与丙氨酸和谷氨酸含量增加有关。盐度增加会提高硬度和剪切力,导致持水能力增加。盐度提高了 DHA 比率,降低了动脉粥样硬化指数和血栓形成指数。结合风味氨基酸和核苷酸的增加,盐度提高了草鱼的鲜味。这些研究结果表明,在盐度条件下临时饲养可能是改善成年草鱼肉质的一种实用方法。

期刊介绍: Antioxidants (ISSN 2076-3921), provides an advanced forum for studies related to the science and technology of antioxidants. It publishes research papers, reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
