Bioactive peptides derived from bovine and porcine co-products: A review

Abstract

The use of meat processing co‐products to recover economically valuable food ingredients, with health‐promoting properties represents an opportunity to enhance the economic performance of the meat industry and to reduce the environmental impact of meat production. This paper discusses the potential of meat processing co‐products for use as substrates for bioactive peptide generation with varied bioactivities including antioxidant, antimicrobial, and antihypertensive properties. Moreover, the current state‐of‐art of meat‐derived bioactive peptides is reviewed with a focus on peptides with proven in vivo bioactivities. Practical applications Meat processing co‐products represent a problem for meat processors due to the large volumes generated and its high pollutant load. These co‐products are usually used for low‐value purposes. However, co‐products such as blood or lung can be used as resources for the generation of bioactive peptides with health‐promoting properties which could be used as ingredients in the functional foods industry.

Comparative peptidomic profile and bioactivities of cooked beef, pork, chicken and turkey meat after in vitro gastro-intestinal digestion

“…Bioactive peptides have been defined as short protein fragments that may have a positive impact on human health [3]. These peptides are inactive within the sequence of the parent protein and can be released following enzymatic hydrolysis such as in the gastro-intestinal tract or during food processing [4,5]. The beneficial health effects of bioactive peptides include antimicrobial, antioxidative, dipeptidyl peptidase-IV (DPP-IV) and angiotensin-converting enzyme (ACE) inhibition, antihypertensive and immunomodulatory activities [3,5].…”

Bromelia karatas and Bromelia pinguin: sources of plant proteases used for obtaining antioxidant hydrolysates from chicken and fish by-products

“…It is important to use proteins of animal origin from different species to obtain BPs [9,10]. In the last few years, the interest for the production of these biomolecules from by-products such as bird feathers, blood, viscera, skin, among others has increased [7,11,12], which represent a valuable source of protein and other essential nutrients [13].…”

The identification and characterisation of novel bioactive peptides derived from porcine liver

“…Once the peptide sequences have been identified they can be cross-checked with databases containing known BAP sequences and/or identify known BAP sequences present in larger peptides or in proteins. Examples of types of BAP activities researched in this fashion are ACE inhibition ( Lafarga et al., 2017 ), antioxidant activity ( Bechaux et al., 2020 ; Borrajo et al., 2020 ; López-Pedrouso et al., 2020 ; Yu et al., 2017 ), immunomodulating activity, and antimicrobial activity ( Borrajo et al., 2020 ; Capriotti et al., 2015 ).…”
