“…However, the AA content in LPC reported herein was higher than the AA content of other marine molluscs, for example, pearl mussel protein isolate (65.73 g/100 g) . In addition, the EAA content of the LPC herein was numerically lower than that reported for other mollusc and crustacean samples, such as oyster protein isolate (47 ± 1%) and krill protein isolate (50.9 ± 0.9%) …”

“…Following isolation, the protein content in the LPC was increased to 66.01 ± 1.67%. Similarly, in a study conducted by Zheng et al on marine molluscs and crustaceans, the protein contents of oyster (Crassostrea hongkongensis) and krill (Euphausia superba) protein isolates obtained using a pH-shift approach were reported to be 67.42 ± 0.65 and 54.27 ± 0.25% (dry weight basis), respectively. However, the authors did not provide the N conversion factor used in that study.…”

This study investigated the characterization of proteins from the Irish limpet (Patella vulgata) and assessed the in vitro biological activities of hydrolysates obtained following gastrointestinal digestion (INFOGEST) of a limpet protein concentrate (LPC). The physicochemical properties and the digestibility of the LPC were investigated, along with the angiotensin-converting enzyme (ACE) inhibition and antioxidant activities of the LPC-digested samples. All the digested samples examined outperformed the LPC in terms of activity. Peptides were identified using LC–MS/MS after digestion. A total of 38 and 19 peptides were identified in LPC-G and LPC-GI, respectively, using a database search and a de novo approach. Most of the identified peptides had hydrophobic amino acids, which may contribute to their antioxidant and ACE inhibitory activities. The findings of this study showed that LPC has high nutritional quality with good digestibility and could serve as a potential source of antioxidative and ACE inhibitory peptides following gastrointestinal digestion.
