Abstract
A simpler strategy was carried out to identify dipeptides in dry-cured ham. Ultrafiltration following MALDI-ToF MS allows a rapid peptide identification. AH, AL, DD, EV and VF were identified in samples with different processing times. Bioactive or tasting food-derived dipeptides can be identified by this methodology.
The processing of dry-cured ham results in the generation of small peptides by the action of endogenous enzymes on muscle proteins. Common proteomic workflows involve previous separation techniques based on liquid chromatography which are expensive and time-consuming. In this study, a convenient proteomic approach based on MALDI-ToF is proposed for the first time for the detection of dipeptides in Spanish dry-cured ham. Dipeptides AH, AL, DD, EV, and VF were identified in hams of 18 and 24 months of dry-curing. This work provides insights on the efficiency of a new peptidomic workflow for the short peptide identification from a complex food matrix and permits to evaluate the sample in terms of the presence of taste-related and bioactive dipeptides.

Abstract
A systematic insight into the structure-function properties of small bioactive peptides is of great importance. Herein, peptidomics and computational methodology were adopted to investigate the stabilization patterns and building blocks of antioxidant peptides resulting from proteolysis during the ripening of Spanish dry-cured ham (9-24 months of processing). The results showed that native peptides underwent manufacture-induced steric/redox stress, while homogeneous/heterogeneous p-π/π-π interaction significantly improved the ABTS+ inhibition activity of hydrophobic peptides. However, for more hydrophilic peptides, the intrinsic π-interaction system (i.e., cation-π and π-π packing) substantially interfered with ABTS+/DPPH scavenging events when compared to the aromatic residues. Semi-quantitative peptidomics and molecular simulation/docking revealed that VFSSQGQSELILLQK and LCPSPDGLYL are two potential antioxidant peptides at the late ripening-drying. They had distinctive self-folding destinies following solvation owing to varying charged/hydrophobic properties of termini and hydrogen atom donor, allowing different flexibility of backbone and interactive surface towards free radicals ex situ followed by electron/proton transfer.

Abstract
Microenvironmental factors may influence the antioxidant efficacy of food-derived peptides. This study evaluated the in vitro antioxidant properties of peptides released during the ripening (9 to 24 months of processing) of Spanish dry-cured ham (Biceps femoris muscle) assisted by spectral-chromatographic methodologies. Results indicated that 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical-cation (ABTS●+) quenching capacity of peptide extracts significantly increased (P < 0.05) until 24 months whereas peroxyl radical (ROO●) scavenging activity increased slowly and remained with non-significant change (P > 0.05) between 15 and 24 months. However, both ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl radical (DPPH●) scavenging ability significantly decreased (P < 0.05) at 24 months. Additionally, morphological traits of peptide extracts suggested that a prolonged ripening enabled the formation/reconstruction of intra-/inter-molecular interactions in dispersion medium. Meta-analysis of chromatographic and spectral fingerprinting proved that the non-conjugated/π-conjugated oligomers mediated by aromatic moieties probably differentiated DPPH● and ABTS●+ antioxidant performance of peptides, showing a potentially altered solvent polarization process.

Abstract
Meat and meat products constitute an important source of nutrients and play vital roles for growth, maintenance and repair of the body. In addition to the high quality of proteins, meat is also regarded as a major resource to produce bioactive peptides. Meat processing industry also produces by-products such as bones, blood and viscera, which could be further used for the production of bioactive compounds. In the physiological analysis, meat bioactive peptides have been reported to exert antioxidant, anti-hypertensive, anti-inflammatory, anti-microbial and antitumoral activities, which endow nutritional and functional value of meat. With the objective to exert the functional effect, the bioavailability should also be considered due to the degradation by digestion enzymes and the absorption process in intestinal mucosa. In this chapter, the general source, the enzymatic hydrolysis, the physiological effects as well as the bioavailability of bioactive peptides in meat are discussed.

Abstract
AbstractHigh cholesterolemia is a key risk factor for the development of cardiovascular diseases, which are the main cause of mortality in developed countries. Most therapies are focused on the modulation of its biosynthesis through 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoAR) inhibitors. In this sense, food-derived bioactive peptides might act as promising health alternatives through their ability to interact with crucial enzymes involved in metabolic pathways, avoiding the adverse effects of synthetic drugs. Dry-cured ham has been widely described as an important source of naturally-generated bioactive peptides exerting ACEI-inhibitory activity, antioxidant activity, and anti-inflammatory activity between others. Based on these findings, the aim of this work was to assess, for the first time, the in vitro inhibitory activity of HMG-CoAR exerted by dipeptides generated during the manufacturing of dry-cured ham, previously described with relevant roles on other bioactivities.The in vitro inhibitory activity of the dipeptides was assessed by measuring the substrate consumption rate of the 3-hydroxy-3-methylglutaryl CoA reductase in their presence, with the following pertinent calculations.Further research was carried out to estimate the possible interactions of the most bioactive dipeptides with the enzyme by performing in silico analysis consisting of molecular docking approaches.Main findings showed DA, DD, EE, ES, and LL dipeptides as main HMG-CoAR inhibitors. Additionally, computational analysis indicated statin-like interactions of the dipeptides with HMG-CoAR.This study reveals, for the first time, the hypocholesterolemic potential of dry-cured ham-derived dipeptides and, at the same time, converges in the same vein as many reports that experimentally argue the cardiovascular benefits of dry-cured ham consumption due to its bioactive peptide content.

Abstract
Large amounts of meat by- and co-products are generated during slaughtering and meat processing, and require rational management of these products for an ecological disposal. Efficient solutions are very important for sustainability and innovative developments create high added-value from meat by-products with the least environmental impact, handling and disposal costs, in its transition to bioeconomy. Some proteins have relevant technological uses for gelation, foaming and emulsification while protein hydrolyzates may contribute to a better digestibility and palatability. Protein hydrolysis generate added-value products such as bioactive peptides with relevant physiological effects of interest for applications in the food, pet food, pharmaceutical and cosmetics industry. Inedible fats are increasingly used as raw material for the generation of biodiesel. Other applications are focused on the development of new biodegradable plastics that can constitute an alternative to petroleum-based plastics. This manuscript presents the latest developments for adding value to meat by- and co-products and discusses opportunities for making meat production and processing more sustainable.

Abstract
In this study, orange seed proteins were hydrolyzed by Alcalase enzyme at different enzyme concentrations 1-3% (v/w) and hydrolysis times (2-5 h), to obtain bioactive peptides showing antioxidant, Angiotensin-converting enzyme (ACE) -inhibitory, and hypoglycemic activities. The highest biological activities (p < 0.05) were achieved by using a hydrolysis time of 5 h and an enzyme concentration of 2%. Orange seed protein hydrolysate (OSPH) was prepared under these conditions, and peptides were isolated and purified by using size-exclusion chromatography and high-performance liquid chromatography, respectively. The fractions that showed the highest biological activities were analyzed by mass spectrometry in tandem, and a total of 63 peptide sequences were found. Moreover, the effect of simulated gastrointestinal digestion on the bioactivity of the fractions was studied, and the novel peptide sequences generated were also identified. Overall, despite there being some differences in the profile of peptide sequences obtained, the main results showed non-significant differences in the analyzed bioactivities after simulated gastrointestinal digestion.

Abstract
Chlorpyrifos (CPF) is an organophosphorus pesticide used in poultry to prevent and/or kill insects and such as preserving agents of poultry feed. Exposure continues to CPF can promote its accumulation at trace concentrations in animal tissue. The toxicological effects of these residues (carcinogenicity, genotoxicity, and neurological disorders) have been related to oxidative stress. Nevertheless, it is still unknown if these trace concentrations might promote oxidative stress in muscle proteins since chicken meat proteins are susceptible to undergo oxidation reactions. Moreover, protein oxidation has been related to a decrease in the nutritional value in of meat. To investigate the oxidative effect of CPF on chicken breast proteins, peptidomics and proteomics analysis were used. For this, chicken breast samples were exposed to CPF and subjected to simulated gastrointestinal digestion. The identification of oxidized peptides from digested and undigested proteins were performed by LC MS/MS (nanoESI qQTOF). Prior to mass analyses undigested proteins were trypsinated. Data were analysed using MASCOT and ProteinPilot v 4.5 software. In this study, 90 and 107 oxidized peptides from digested proteins of control and exposed samples were identified, respectively. These peptides corresponding to 12 oxidized proteins. Meanwhile, 260 and 324 oxidized peptides from undigested proteins (control and exposed samples) were identified, which corresponding to 19 and 17 proteins, respectively. Collagen was protein more susceptible to oxidation promoted by chlorpyrifos in digested and undigested proteins. Identification of these oxidized proteins from simulated digestion provides an important insight about the impact of substances like certain veterinary drugs at trace concentrations on the nutritional value of chicken breast meat.

Abstract
Nitrite and nitrate have been traditionally used for the preservation of meat products because of the effective antimicrobial action of nitrite against Clostridium botulinum, the outgrowth of its spores as well as other bacteria. However, the use of nitrite and nitrate has been questioned in last half century due to the possible generation of N-nitrosamines through reaction of nitrite with secondary amines. Nitrite replacement strategies began in the 70s addressing these issues and instigated searches for natural alternatives to nitrate and nitrite, or for natural sources of nitrite and nitrate such as vegetable extracts. These alternatives have been considered by producers and consumers as an attractive practice even though they may also have some risks. This manuscript reviews and discusses the chemistry, safety, and regulatory considerations in the use of nitrite and nitrate from natural origin for the preservation of meat products.

Abstract
Food-derived bioactive peptides are promising compounds for the prevention and treatment of cardiovascular diseases, the main cause of mortality in developed countries. The aim of this work was to determine the in vitro anti-inflammatory, antioxidant, and angiotensin I-converting enzyme (ACE-I) inhibitory activities of twenty-four peptides that were identified in Spanish dry-cured hams. For the first time, some peptides such as PSNPP, HCNKKYRSEM and FNMPLTIRITPGSKA showed anti-inflammatory activity expressed as platelet-activating factor-acetylhydrolase, autotaxin, and lipoxygenase inhibition. Peptides MDPKYR and TKYRVP were the strongest antioxidants, whereas GGVPGG, TKYRVP, and HCNKKYRSEM showed the highest ACE-I inhibitory activity. Additionally, several peptides such as KPVAAP, MDPKYR, TKYRVP, and HCNKKYRSEM exerted more than one of the assayed activities, increasing their health-enhancing potential. More studies are needed to evaluate the bioavailability of such peptides and their in vivo effect. This would contribute to consider dry-cured ham as a source of peptides beneficial for cardiovascular health.
