Numerous studies have shown that in-pond raceway aquaculture system (IRAS) is the future of industrialized and large-scale pond culture, and rhubarb extracts have been proved to improve immunity, resist stress and regulate lipid metabolism This study sought to investigate the difference between the IRAS (7.0 kg/m3) and traditional pond (0.52 kg/m3) in the fresh meat quality of Megalobrama amblycephala, and further the role of dietary rhubarb extracts on fish in IRAS. M. amblycephala (220-250 g) were raised in three different conditions: IRAS group: IRAS (7.0 kg/m3) culture fed with a normal formulated diet, IRAS-R group: IRAS (7.0 kg/m3) culture fed with a functional diet containing 0.05% rhubarb extracts, TP-R group: traditional pond (0.52 kg/m3) culture fed a functional diet containing 0.05% rhubarb extracts The fresh meat quality indicators were analyzed after four months of breeding. The electronic nose analyses elucidated differences in the odor of the raw fish from the three examined groups. Specifically, out of the 68 volatile flavor compounds identified in the three groups (including ketones, aldehydes, acids, alkanes, and alcs.), 41 were detected in the TP-R group, 44 in the IRAS-R group, and 54 in the IRAS group. The aldehydes were the main contributor to fishy odor in the fresh meat of M. amblycephala, and the main aldehyde in three groups was hexanal, the contents were all higher than 8500μg/kg. IRAS-R group resulted in a significant increase in ketones compared to TP-R group (1322.28μg/kg) and IRAS group (1228.36μg/kg), reaching a total content of 2997.44μg/kg, which was mainly composed of 2,3-octanedione, 2,3-pentanedione, 3,5-octadien-2-one, non-3,5-dien-2-one, and 3-octen-2-one. IRAS improved the shear force, total amino acids, essential amino-acid, adenosine monophosphate (AMP), hypoxanthine ribonucleoside (HxR), and decreased the crude lipid, saturated fatty acid, guanosine monophosphate (GMP) of M. amblycephala meat compared with traditional pond (P < 0.05). IRAS with dietary rhubarb extracts further enhance shear force, and the content of delicious amino acids, unsaturated fatty acids (UFAs), ω-3 unsaturated fatty acids (e.g., EPA + DHA), ω-6 unsaturated fatty acids, and UFA/SFA (unsaturated fatty acids/saturated fatty acids) ratios compared with IRAS group(P < 0.05). Therefore, this study provides important insights into the effects of IRAS and rhubarb extracts on fish meat quality and establishes a methodol. framework for the evaluation of how different culture systems and plant-based supplements affect muscle characteristics. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Safety of Oct-1-en-3-ol).
Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Safety of Oct-1-en-3-ol
