“…Therefore, chemical analysis for the degree of pigmentation should be applied to verify our results. Crustacean chroma is the major factor responsible for customer acceptability, because redder hepatopancreases are recognized for their superior nutritional quality [6,24,25]. However, there is no standard color for E. sinensis.…”

“…The differences in fatty acid content and composition might be the potential cause for the changes in carotenoids because carotenoids are liposoluble pigments. The inhibition of fatty acid metabolism is associated with a reduction in carotenoid uptake and metabolism [6]. In crabs, carotenoid extracts have high levels of unsaturated fatty acids including C16:1, C18:1, C18:3, and C20:1 [38].…”

“…Local farmers should consider harvesting male crabs with a redder hepatopancreas by adjusting their diets and environmental conditions [9,48,49]. In crabs, the desired color can be achieved by supplementing the feed with astaxanthin, the carotenoid responsible for the natural color [6]. However, the cost of synthetic astaxanthin is high, which adds significantly to the costs of feed and production.…”

“…However, the different nutritional profiles and flavors of E. sinensis with different hepatopancreas a* values have not been comprehensively clarified. Significant increases in carotenoid and fatty acid content were obtained with increasing hepatopancreas a* values in E. sinensis fed astaxanthin [6]. Compared with green-black crabs, the EPA content in muscles, hepatopancreases, and ovaries were higher in female purple crabs with higher hepatopancreas a* values [8].…”

In this study, we investigated the body characteristics, carotenoid composition, and nutritional quality of Eriocheir sinensis with different hepatopancreas redness (a*). We distributed the crabs into two groups based on the hepatopancreas a* values and compared their body characteristics, chroma, carotenoid composition, and protein, lipid, total sugar, amino acid, and fatty acid content via paired t-test. The results revealed that the relationships between hepatopancreas a* values and crab quality are sex specific. In female crabs, the differences in nutritional characteristics were evident mainly in the hepatopancreases and ovaries. In the redder hepatopancreases, the content of zeaxanthin and β-carotene increased, and the levels of C22:6n3 and C20:5n3 decreased (p < 0.05). In the ovaries, the content of astaxanthin, canthaxanthin, β-carotene, umami, and sweet amino acids were lower in the redder hepatopancreas crabs (p < 0.05). In male crabs, there were positive relationships between hepatopancreas a* and amino acid and fatty acid content. The content of leucine, arginine, and total umami amino acids in muscles and of unsaturated fatty acids and n-6 polyunsaturated fatty acids in hepatopancreases and testicles increased with increasing hepatopancreas a* values (p < 0.05). Therefore, the redder the hepatopancreas, the higher the nutritional quality of male crabs.

This study aimed to investigate the effects of adding different levels (0, 50, 100, 200 and 300 mg/kg) of dietary β‐carotene on the color and flavor quality of adult female E. sinensis ovaries. Adding moderate amount of β‐carotene to the feed could regulate the distribution of carotenoids, fatty acids, and free amino acids in the ovaries of E. sinensis, as well as increase the content of total carotenoids, total fatty acids, sweet and umami amino acids in the ovaries. The dietary β‐carotene have limited coloring effects and a significant impact on the flavor of the ovaries. During thermal process, the addition of 100 mg/kg β‐carotene could effectively promote formation of aroma precursors and generate more characteristic aroma components (2‐methylbutanal, 3‐methylbutanal, hexanal, benzaldehyde, methylpyrazine). However, excessive β‐carotene supplementation (300 mg/kg) led to adverse effects on physiological metabolism and flavor of E. sinensis ovaries. Considering both feed cost and quality improvement, β‐carotene supplementation at 100 mg/kg can be considered the optimal feed supplementation for adult female E. sinensis within a 70‐day rearing period to improve edible quality of ovaries.
