Bioactive peptides are derived from food proteins and exert a positive effect in humans due to its health-promoting properties. In recent years, there has been a growing interest in de novo design and construction of novel synthetic peptides that mimic protein secondary structures to develop potent peptide analogs and peptidomimetics displaying unique pharmaceutical properties (Kishore, 2004). Some of the fractions exhibited great 1,1-diphenyl-2-picrylhydrazyl radical-scavenging activity, varying from 39 to 92% as well as superoxide ion extinguishing ability with values from 41.7 to 50.3% of the antioxidant activity, suggesting the presence of peptides with antioxidant activity. In this chapter, the most recent investigations supporting the potential health benefits of bioactive peptides in fermented foods on cardiovascular, nervous, gastrointestinal and immune systems, as well as on bones and adipose tissue are reviewed. On the other hand, some BP have been identified in fermented dairy products, and there are already a few commercial dairy products enriched with blood pressure-reducing milk protein peptides. BP isolated and identified from crustaceans, regulate a large number of physiological functions, including colour change, heart activity, exoskeletal and visceral muscles, metabolic function, development, metamorphosis, and reproduction.

Martinez-Villaluenga, ... J. Frias, in, Fermented Foods in Health and Disease Prevention, Phytochemical-Related Health-Promoting Attributes of Sorghum and Millets, Marine Processing Proteinaceous By-Products: A Source of Biofunctional Food Ingredients. Moreover, Ohara et al. To be considered bioactive, a dietary component should impart a measurable biological effect at a physiologically level. Some BP have been prepared by chemical synthesis. Milk proteins are a rich source of biologically active peptides that are released during GI digestion or food processing (Fitzgerald and Meisel, 2003; Meisel and Fitzgerald, 2003). Examples of peptides include the hormone oxytocin, glutathione (stimulates tissue growth), melittin (honey bee venom), the pancreatic hormone insulin, and glucagon (a hyperglycemic factor). Peptides with this type of activity are generically termed as bioactive peptides even though other activities such as antioxidant, antimicrobial, opioid, antithrombotic, antidiabetic, etc … also fit into the general bioactive peptide term. Eggs are known as a source of valuable proteins in human nutrition and have been considered an important source of many BP (Wu et al., 2010; Zambrowicz et al., 2011; Bhat et al., 2015a) which may find applications in medicine and food industry (Sun et al., 2016). Using liquid chromatography-mass spectrometry (HPLC-MS) and tandem mass spectrometry (MS), a large number of medium and low-MW BP (opioid, phosphopeptides) were identified in human milk from mothers of pre- and full-term infants. On the other hand, it has been demonstrated, that digestion of casein produces phosphorylated peptides that exhibit both hydrophilic and lipophilic antioxidant activity due to both metal ion sequestering and quenching of ROS (Clare and Swaisgood, 2000). By far, bovine milk (Torres-Llanez et al., 2005; Korhonen, 2009; Léonil, 2014; Mohanty et al., 2015; Mohanty et al., 2016), cheese (Pritchard et al., 2010), and dairy products (Choi et al., 2012) are the greatest sources of bioactive proteins and peptides derived from foods. There is an expanding focus on bioactive peptides because of their health benefits, and they have been considered as the new generation of biologically active regulators (Sánchez and Vázquez, 2017). Moreover, in sonophoresis applications, low-frequency ultrasound can be used to transport high-MW peptide drugs (Kadam et al., 2015). (, Jung W.-K.Qian Z.-J.Lee S.-H.Choi S. Y.Sung N. J.Byun H. G.Kim S. K. (, Kadam S. U.Tiwari B. K.Álvarez C.O’Donnell C. P. (, Kamau S. M.Cheison S. C.Chen W.Liu X.-M.Lu R.-R. (, Kobayashi MAoki S.Gato K.Matsunami K.Kurosu M.Kitagawa I. Aspergillus spp. These results suggested that the peptides derived from velvet antler protein could potentially be used as a promising ingredient in functional foods or nutraceuticals against inflammatory diseases (Zhao et al., 2016). Industrial-scale production of such peptides is, however, hampered by the lack of suitable technologies which retain or even enhance the activity of BP in food systems (Korhonen and Pihlanto, 2003; Korhonen and Pihlanto, 2006; Pihlanto, 2006; Kamau et al., 2010). In silico proteolysis and quantitative structure–activity relationship studies of marine algae-derived BP, as well as in vivo evaluation and novel technologies in BP studies and production have been reviewed (Fan et al., 2014). 12.3. Fractionated hydrolysates showed a high concentration of short chain peptides, with significantly higher antioxidant and antihypertensive capacities than fractions with higher MWs. Marine organisms such as fish, shellfish mollusks, marine processing waste, and crustaceans are abundant sources of a myriad of structurally diverse bioactive organic compounds (Aneiros and Garateix, 2004; Lee et al., 2012; Rustad and Hayes, 2012; Cheung et al., 2015; Jo et al., 2017). Digestion studies in vitro have provided evidence that a mixture of peptides (2–4 amino acid residues) obtained from certain food proteins using human digestive enzymes under physiological conditions possess potent antioxidant activity (Zhu et al., 2008). Whey constitutes five major proteins, such as α-lactalbumin, glycomacropeptide, β-lactoglobulin, protease peptone, immunoglobulins, and serum albumin, that together make up 85% of whey protein, whereas casein contains αs1-casein, αs2-casein, β-casein, and κ-casein and have been proven that these peptides are the potent inhibitors of pathogenic organisms such as bacteria e.g. It is now well established that eggs contain numerous substances with potential and demonstrated therapeutic effects, beyond supplying basic nutritional requirements (Zambrowicz et al., 2011). This may represent a technical advantage for B. bifidum that reduces the pH at a slow enough rate to facilitate the peptide generation without the need for pH control (Gonzalez-Gonzalez et al., 2013). Further studies are therefore required to ascertain the role of peptides derived from casein as nutritional and pharmacological factors (Ferranti et al., 2004). For instance, BP can be produced from bovine caseins by growing Streptococcus thermophilus 4F44 (247 peptides identified, 143 were derived from β-casein) (Chang et al., 2014). Processes combining an electrical field as a driving force and porous membranes have been developed for the separation of biopeptides to obtain better-purified products. In a recent study, a new strategy for the recovery of waste proteins from olive seed with the potential to produce antioxidant and antihypertensive peptides has been investigated. This membrane bioreactor technology equipped with ultrafiltration membranes is recently emerging for the development of bioactive compounds and considered as a potential method to utilize marine fish proteins as value-added nutraceuticals with beneficial health effects. Mehdi Mohammadian, ... Farhad Alavi, in Dairy in Human Health and Disease Across the Lifespan, 2017. Similarly, hydrolysis of pea proteins with alcalase produced CaM-binding peptides (Li and Aluko, 2010). Hidden between the chemical structure of proteins present in food matrixes, and other natural sources, lie an immense amount of BP. Alaska pollock frame protein is normally discarded as an industrial by-product in the processing of fish. Research effort in the field of BAPs has increased in the last few years. Peptides isolated and characterized from cow milk proteins show mineral-binding, opioid, ACE inhibitory, immunomodulatory, cytotoxicity, anti-carcinogenic, antibacterial, and anti-thrombotic activities. Stones of fruits such as plum (Prunus domestica L.) are rich in proteins and may be a cheap source of BP that could be useful for the food and pharmaceutical industries. Certain food proteins, chiefly milk caseins, may act as a precursor of bioactive peptides with varying physiological benefits (Özer and Kirmaci, 2010). Peptides structurally related to the insulin receptor (IR)-binding protein mcIRBP-19 have been identified in various plants that have IR kinase-activating abilities similar to mcIRBP-19 that has a proved blood glucose-lowering activity that exhibits IR-binding potentials (Lo et al., 2016). Examples: Carnosine ( β-alanyl-L-histidine) Anserine (β-alanyl-N-methylhistidine) Aspartame (Asparagine-phenylalanine) 2. Bioactive Peptides & Free Amino Acids in Poultry Protein Hydrolysates help enhance feed intake, especially during stressful time. Stability of Spanish dry-cured ham-derived ACE-inhibitory peptides after: (A) 6 min incubation at various temperatures and (B) 117°C incubation at different times. Copyright © 2020 Elsevier B.V. or its licensors or contributors. A.C. Neves, ... R.J. FitzGerald, in Protein Byproducts, 2016. Antioxidant proteins and peptides have also been identified in egg (Sakanaka and Tachibana, 2006), potato, and gelatin (Je et al., 2005). Bioactive peptides can be purified from enzymatic hydrolysis of different marine fish sources using appropriate proteolytic enzymes. Douchi, also a soybean product fermented by fungal cultures (e.g. Studies on potentially hypotensive milk protein hydrolysates illustrate the significant difference between allergenicity and immunogenicity. The results indicated that soybean proteins experimented degradation during GI digestion generating a large number of BP, some with established activity, and some with predicted antimicrobial activity. Enzymatic hydrolysis The most common way to produce bioactive peptides is through enzymatic hydrolysis of whole protein molecules. Bioactive peptides naturally generated during food processing may be directly ingested either raw or after heat treatment (pasteurization, sterilization, cooking, etc.). In other words, any substance which resembles the molecular structure of smaller proteins. Antimicrobial α-helical peptides have also been described in the venoms of spiders. Escherichia, Helicobacter, Listeria, Salmonella, and Staphylococcus; yeast, and filamentous fungi (Mohanty et al., 2016). In the study, peptides with high ACE-inhibitory activity were isolated from Spanish dry-cured ham and submitted to a variety of thermal treatments rather usual in food processing (Escudero, Mora, & Toldrá, 2014). (2007) showed that Ala-Hyp-Gly and Ser-Hyp-Gly remained intact 4 h after being administrated, which indicates that these peptides also resisted digestion and were able to be assimilated into the bloodstream. However, to reduce the production cost, crude protein mixtures are preferred (Zarei et al., 2012). Haemoglobin fragments can have a profound physiological function. A variety of naturally formed bioactive peptides have been found in fermented dairy products, such as yoghurt, sour milk and cheese. ADAMB was 4- and 38-fold more potent as an analgesic than morphine following oral and s.c. administration (Aldrich and McLaughlin, 2012). Antimicrobial peptides (AMPs) are an abundant and diverse group of molecules that are produced by many tissues and cell types in a variety of invertebrate, plant, and animal species. The stability of bioactive peptide extracts against different thermal treatments was recently assayed. The dipeptide carnosine (β-alanyl-histidine), and its related dipeptides anserine (β-alanyl-1-methylhistidine) and balenine (β-alanyl-3-methylhistidine), have high antioxidant and pH-buffering properties in muscle cells. Cyclo(-Phe-Phe) present in chicken essence acted as a dual inhibitor of the serotonin transporter and acetylcholinesterase. Bioactive peptides usually contain 3–20 amino acid residues, and their activities are based on their amino acid composition and sequence (Pihlanto-Leppala, 2000). Examples of peptides with known activity. AMPs can be classified into three families according to different structural features: 1. α- helical linear peptides, 2. disulfide-bridged cyclic and open-ended cyclic peptides, and 3. peptides whose primary structures have a high content of some amino acid residues (e.g. Examples of short peptides from marine origin. For instance, the effects of Allium sativum on total phenolic content, proteolysis by o-phthaldialdehyde assay, antioxidant activity by radical inhibition and capacity to inhibit α-amylase and α-glucosidase activities in vitro were higher in camel milk yogurt (MY) than cow MY (Amal and Ahmad, 2014). C. Martinez-Villaluenga, ... J. Frias, in Fermented Foods in Health and Disease Prevention, 2017. However, the presence of sequences with other biological activities such as antihypertensive, anti-thrombotic, hypocholesterolemic, immunomodulation, cytotoxicity, antioxidant, antimicrobial, antigenic, or opioid was also confirmed (Catala-Clariana et al., 2013). This protein plays multifunctional roles in the translation of intracellular messages (Klee and Vanaman, 1982). 34. Moreover, whole peptides and single amino acids are less easily absorbed across the gastrointestinal membrane than short peptides with two to six amino acids (Grimble et al., 1986). BP play a significant role in human health by affecting the digestive, endocrine, cardiovascular, immune, and nervous systems. Apart from its importance as a growth factor, Lf, an iron-binding glycoprotein present in the milk of all mammals, has antimicrobial properties and shows immunomodulating effects. © The Author 2017. The presence of antioxidant peptide segments in proteins may help to explain why dietary protein intake can promote animal and human health beyond the standard nutritional benefits exerted (Elias et al., 2008). Lactobacillus helveticus) (Gobbetti et al., 2002; Meisel, 2005; Korhonen and Pihlanto, 2006; Korhonen, 2007; Dziuba and Dziuba, 2014). Peptides with opioid activities are derived from wheat gluten or casein, following digestion with … An increase in insulin concentrations in individuals with celiac disease has been observed, but further studies are required to determine whether increased insulin concentrations is related to an increased risk for hyperinsulinemia (Janas et al., 2016). Conventional pressure-driven processes can be used for amino acids and peptides separation but are limited by their fouling problems and their low selectivity when separating similar sized biomolecules (Bazinet and Firdaous, 2009). When a whey protein concentrate was treated with trypsin and the obtained peptides were separated using membrane ultrafiltration/nanofiltration, β-lactoglobulin peptides predominated in the hydrolysate (Arrutia et al., 2016b). The endogenous dipeptide cyclo(His-Pro) that is present in the CNS and several body fluids and the GI tract, has a neuroprotective role. Numerous bioactive peptides have been reported in recent years as naturally present or generated from food proteins of different origins like milk, eggs, soya, fish, and meat. It is often present in large amounts in chickens, during inflammation and infection processes. In this sense, the most extensively studied bioactivity during the last decade has been the antihypertensive activity through the measurement of angiotensin I-converting enzyme (ACE) inhibitory activity. However, the efficacy of peptide intake for borderline hypertensives still requires further investigation. Casein Derived Antibacterial Peptides show inhibitory activity against Streptococcus mutans, Streptococcus sanguis, Porphyromonas gingivalis, Streptococcus sobrinus, Sthaphylococcus aureus, Escherichia coli, and Salmonella typhimurium. Schematic representation of the production of bioactive peptides (adapted from Danquah and Agyei, 2012). A novel strategy to enhance ACE inhibitory activities of navy bean consist in the preparation of navy bean milk (NBM) which was then subjected to fermentation with Lactobacillus bulgaricus, Lactobacillus helveticus MB2-1, Lactobacillus plantarum B1-6, and Lactobacillus plantarum 70810. The major role of milk proteins is to supply amino acids and nitrogen to the young mammals and constitute an important part of dietary proteins for the adult (Sharma et al., 2011).
