“…A number of previous studies have described the ACEinhibitory activity of marine protein hydrolysates produced from different species such as yellowfin sole (Limanda aspera) (Jung et al, 2006), pacific hake (Merluccius productus) (Cinq-Mars & Li-Chan, 2007), sardinelle (Sardinella aurita) (Bougatef et al, 2008), cuttlefish (Sepia officinalis) (Balti, Nedjar-Arroume, Yaba-Adjé, Guillochon, & Nasri, 2010), loach (Misgurnus anguillicaudatus) (Li, Zhou, Huang, Sun, & Zeng, 2012) and chum salmon (Oncorhynchus keta) (Lee, Jeon, & Byun, 2014). However, to the best of the authors' knowledge, apart from sardine (S. pilchardus) which has been extensively studied (Bordenave et al, 2002;García-Moreno, Pérez-Gálvez, Espejo-Carpio, et al, 2013;Matsui et al, 1993), there is no previous work on the production of fish protein hydrolysates with ACE-inhibitory activity from the chosen discarded species in the Alboran Sea.…”
