The present study aimed to investigate the interactive effects of dietary supplementation to the feed with astaxanthin and/or DHA on the color and odor of Eriocheir sinensis ovaries. The results revealed that astaxanthin supplementation significantly increased redness of E. sinensis ovaries (P < 0.05). Moreover, the addition of either astaxanthin or DHA alone to the feed affected the deposition of carotenoids and fatty acids in E. sinensis ovaries. More importantly, the simultaneous supplementation of astaxanthin and DHA significantly improved color, carotenoid content, and polyunsaturated fatty acid content (P < 0.05) in E. sinensis ovaries, as well as increased the content of aroma compounds during thermal processing. Based on the present findings, the optimal combination of dietary astaxanthin and DHA is 100 mg/kg of synthetic astaxanthin and 0.15% of DHA, respectively, which could improve color and odor quality of ovaries for E. sinensis.
本研究旨在探讨饲料中添加虾青素和/或二十二碳六烯酸（DHA）对中华绒螯蟹（Eriocheir sinensis）卵巢颜色和气味的交互影响。结果表明，虾青素的添加显著增加了中华绒螯蟹卵巢的红色度（P<0.05）。此外，单独添加虾青素或 DHA 都会影响中华绒螯蟹卵巢中类胡萝卜素和脂肪酸的沉积。更重要的是，同时添加虾青素和 DHA 显著改善了中华绒螯蟹卵巢的颜色、类胡萝卜素含量和多不饱和脂肪酸含量（P<0.05），并增加了热加工过程中香气化合物的含量。基于本研究结果，饲料中虾青素和 DHA 的最佳组合分别为 100mg/kg 合成虾青素和 0.15%的 DHA，可改善中华绒螯蟹卵巢的颜色和气味质量。
