Consumers’ perception of volatiles determines their preferences and choices of food. Furthermore, various factors, such as varieties, origin, gender, and edible parts, may influence volatiles. The perception of edible parts of E. sinensis in two origins (Chongming and Taixing) regarding overall hedonic score (9-points), just-about-right scale (5-points), and intensity of attributes (7-points) were analyzed. The results showed that consumers preferred the hepatopancreas odor of female crabs in Chongming, with an overall preference of 6.84 and RMAT (calculate the R-index by matrix) values >52.93%. The crabs’ origin (different feeding and rearing condition) was the primary reason for the odor profiles. The appropriate meaty and toasted odor in the hepatopancreas increased the overall preference by approximately 14.65–20.60%. Furthermore, 2-acetylthiazole, a volatile compound with a fatty odor, may significantly affect preferences and consumption behavior.
