“…The reducing power of Rv hydrolysates exhibited the similar digestive characteristics to the DPPH radical scavenging activity that the simulated GI digestion decreased the reducing power of hydrolysates. Though, many research reported that the GI digestion improved the reducing power of food resources such as salmon protein (Borawska et al ., ), a similar trend as in our study was also reported for Cape hake by‐products (Teixeira et al ., ).…”

“…It is interesting to note that the simulated GI digestion decreased the DPPH scavenging activity when compared to the undigested samples ( P < 0.05). Though, many research reported the GI digestion improved the DPPH scavenging activity of food resources, a similar trend was also reported for salmon (Borawska et al ., ) and carp (Borawska et al ., ). Unlike Rv visceral mass, intestinal digestion slightly but significantly ( P < 0.05) improved the DPPH radical scavenging activity of Rv meat compared to the gastric digestion.…”

Summary Rapana venosa (Rv) is an abundant marine snail resource with high content of protein. The antioxidant activities of Rv meat and visceral mass during simulated gastrointestinal (GI) digestion and their membrane ultrafiltration fractions were evaluated. Results indicated that visceral mass possessed stronger antioxidant activities than meat. The simulated GI digestion increased the hydroxyl radical scavenging activity while decreased the 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) scavenging activity and reducing power. After membrane ultrafiltration, there were three fractions, that is molecular weight (MW) > 10 kDa, MW 3.5–10 kDa and MW < 3.5 kDa. Fractions with MW > 10 kDa and MW < 3.5 kDa showed the highest hydroxyl, DPPH radical scavenging activity, respectively. Fractions with MW 3.5–10 kDa and MW > 10 kDa showed the highest reducing power for meat and visceral mass, respectively. Rv hydrolysates exhibited significantly higher hydroxyl radical scavenging activity than the positive control vitamin C (Vc) and may serve as useful ingredients for application in food industry nutritional products.

“… 29 , 30 These vascular antagonistic actions with Ang II could also be helped by its free radical reducing and scavenging ability, 30 which can be related to the very hydrophobic nature of its molecular moiety. 31 Interestingly, Ang-(3−4) is effective when administered orally, 26 , 32 , 33 a property associated with its resistance to hydrolysis and its high capacity to permeate intestinal cells. 34 One mechanism proposed to explain these effects involves l -type Ca 2+ channels, independently of Ang II receptors.…”

Angiotensin-(3−4) (Ang-(3−4) or Val-Tyr) is the shorter angiotensin (Ang) II-derived peptide, formed through successive hydrolysis that culminates with the release of Val-Tyr as a dipeptide. It is formed both in plasma and in kidney from Ang II and Ang III, and can be considered a component of the systemic and organ-based renin–angiotensin system. It is potently antihypertensive in humans and rats, and its concerted actions on proximal tubule cells culminate in the inhibition of fluid reabsorption, hyperosmotic urinary excretion of Na+. At the renal cell signaling level, Ang-(3−4) counteracts Ang II-type 1 receptor-mediated responses by acting as an allosteric enhancer in Ang II-type 2 receptor populations that target adenosine triphosphate-dependent Ca2+ and Na+ transporters through a cyclic adenosine monophosphate-activated protein kinase pathway.

“…Así mismo, se favoreció la capacidad de reducción del ion Fe +3 , tanto para la fracción globular sin hidrolizar como para sus hidrolizados a diferentes tiempos de hidrolisis, posiblemente porque durante el proceso de digestión in vitro se liberan péptidos con capacidad antioxidante (Zhu et al, 2008;Borawska et al, 2016).…”

ResumenEn este trabajo se optimizó la reacción de hidrólisis enzimática de proteínas de la fracción globular de sangre bovina usando la metodología de superficie de respuesta. Se evalúo el efecto de la concentración de sustrato (S0: 8-12 %), la relación enzima/sustrato (E0/S0: 4-12 g/100 g proteína) y el pH (8-10), sobre el grado de hidrólisis (GH), en un reactor Batch (temperatura de 55° C, por 2 h). La optimización del modelo estadístico obtenido entregó un máximo GH de 38,08 % para pH: 8,16; S0: 6,6 y E0/S0: 14,7, el cual fue corroborado experimentalmente dando un GH de 36,25 ± 0,3 con sesgo negativo de 5 %. A estas condiciones se tomaron muestras a tres tiempos de hidrólisis para evaluar la capacidad antioxidante, con los métodos químicos conocidos como ORAC, ABTS y FRAP. Se alcanzó mayor capacidad antioxidante a mayor tiempo de hidrólisis. Después de una digestión in vitro se corroboró que la capacidad antioxidante del hidrolizado se conserva.Palabras clave: péptidos bioactivos; hidrólisis enzimática; actividad antioxidante; sangre bovina; proteína Optimization of Enzymatic Hydrolysis of Bovine Blood Cell Fraction by Response Surface Methodology (RSM) and Evaluation of its Antioxidant Properties AbstractIn this paper the reaction of enzymatic hydrolysis of the erythrocyte fraction of bovine blood was optimized through the response surface methodology. The effects of substrate concentration (S0: 8-12 %), enzyme/substrate ratio (E0/S0: 4-12 g/100 g protein) and pH (8-10), on degree of hydrolysis (DH) working to constant temperature of 55° C in a batch reactor, by 2 h were determined. The optimization of the statistical model obtained gave a maximum DH of 38.08 %, with pH 8.16; S0: 6.6 and E0/S0: 14.7, which was experimentally proved giving a DH of 36.25 ± 0.3 with negative bias of 5 %. At the optimal conditions samples were taken at three hydrolysis times to evaluate the antioxidant capacity, which was analyzed with ORAC, ABTS and FRAP methods. Greater antioxidant capacity was obtained at long hydrolysis time. After in vitro digestion it was confirmed that the antioxidant capacity of hydrolyzate remained.
