To improve the ease of eating sea cucumbers, we investigated the impact of puffing temperature (190 °C - 250 °C) and time (1-5 min) on their quality and flavor. As temperature and time increased, sea cucumber puffing significantly enhanced. The microstructure of the puffed sea cucumber exhibited a uniform porous structure at 230 °C for 4 min. However, further puffing treatment caused the void to collapse. A total of 81 volatile organic compounds (VOCs) were identified using HS-GC-IMS, and 18 VOCs with Relative odor activity value (ROAV) ≥1 were identified. The content of fishy compounds, such as dimethyl sulfide, 1-octanal, and 1-nonanal in sea cucumbers gradually decreased with increasing temperature and time. Combined with GC-MS analysis indicating that the flavor of sea cucumbers puffed at 250 °C for 5 min was superior. Our findings suggest new avenues for sea cucumber processing and address the limited research on puffing techniques for protein-based raw materials.

Feeding behavior is regulated by a complex network of endogenous neuropeptides. In chordates, this role is suggested to be under the control of diverse factors including thyrotropin-releasing hormone (TRH). However, whether this regulatory activity of TRH is functionally conserved in non-chordate metazoans, and to what extent this process is underpinned by interactions of TRH with other neuropeptides such as cholecystokinin (CCK, known as a satiety signal), remain unclear.

Sulfated fucan from sea cucumber has received growing interest in recent decades. Insight into the primary structure of sulfated fucan is fundamental to elucidate their bioactivity. The sea cucumber Holothuria mexicana possesses a high market demand, while the structure of its sulfated fucan (Hm-FUC) remains unclear.

Fucoidan from Apostichopus japonicus (Aj-FUC) has shown anti-inflammatory activity, whereas its mechanism was not explicated. This study investigated the anti-inflammatory potential and mechanism of the fucoidan from green and purple A. japonicus (G-FUC and P-FUC) in lipopolysaccharide (LPS)-treated RAW264.

Soft robotics has undergone considerable progress driven by materials that can effectively transduce external stimuli into mechanical actuation. Here, we report the development of a photothermal-responsive hydrogel actuator with shape memory capabilities inspired by the adaptive locomotion of sea cucumbers. This actuator is based on sea cucumber peptides (SCP) and a liquid metal (LM) hydrogel network that is responsive to near-infrared (NIR) light.
