The mealworm (Tenebrio molitor) is now considered to be an alternative source of protein. An enzymatical digestion process may be necessary to increase the biological absorption, distribution, and metabolism of Tenebrio molitor and to maximize its biological functional activities. In this study, we acquired enzymatically hydrolyzed defatted Tenebrio molitors using water extract (WE), pressure (P), and high pressure (HP) processes. The nutritional content was significantly altered by applying pressure to the Tenebrio molitors. The crude ash and carbohydrate content decreased, but moisture content increased with the application of pressure. By increasing pressure, crude protein content increased, however crude fat content decreased progressively. The free amino acid content gradually decreased with increasing pressure. The total free amino acid content of the WE, P, and HP was 332.00, 251.82, and 222.10 mg/mL, respectively. The hydrolyzed H or HP exhibited higher antioxidative activities than WE. H showed the highest antioxidative activities (i.e. total phenolic compounds and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities compared to WE or HP. Interestingly, HP displayed the highest level of other antioxidative activities, such as superoxide dismutase (SOD) and catalase enzyme activities. The variation in antioxidative activities by hydrolyzation methods may be due to the molecular size of the hydrolyzed proteins. All the extractions were sized under 500 Dalton and 65.42% of the HP was sized in this range and 25.98% of P was sized 500~1000 Dalton compared to WP or HP. Therefore, our logical postulation is that the lower than 500 Dalton fraction may display SOD and/or catalase enzymatic activities in HP and the 500~1000 Dalton fraction may enhance phenolic components and ABTS radical scavenging activities in H.
