Next-generation nutraceuticals: bioactive peptides from plant proteases

Abstract

Bioactive peptides are short and specific fragments of proteins with a wide range of biological activities that provide health benefits to the host. These natural peptides are safe and nontoxic and do not show any side effects. Nowadays, the production and characterization of bioactive peptides have been a key area of research as they show great potential as nutraceuticals and functional foods. Thus, bioactive peptides are considered next-generation therapeutic agents that can replace pharmaceutical products with profound adverse effects in the near future. So far, proteolytic hydrolysis has been used as the method of choice for the large-scale production of bioactive peptides. Studies have reported that peptides with specific characteristics can be generated using a particular type of protease. Microbial proteases are the predominantly used ones because of the ease in their production and purification. However, recently, plant proteases have gained a renewed interest as they offer diversity and better specificity compared with other proteases. This review highlights the potential of plant proteases for the production of bioactive peptides and also describes the benefits of bioactive peptides as nutraceuticals.

Targeting Metabolic Diseases: The Role of Nutraceuticals in Modulating Oxidative Stress and Inflammation

“…They possess potent antioxidant properties, acting as effective scavengers of various oxidants, thanks to the presence of phenolic rings with multiple hydroxyl groups in their chemical structure [ 106 ]. In recent years, in addition to the active principles mentioned above, bioactive peptides from plant proteases formulated as nutraceuticals have been considered as the next generation of nutraceuticals [ 107 ]. For example, it has been demonstrated that the clinical effectiveness of bioactive peptides with antihypertensive properties hinges on two crucial factors: how well they resist degradation by gastrointestinal peptidases and their ability to be absorbed into the bloodstream [ 108 ].…”

Chitosan flakes for papain immobilization: improving the stability and reusability of the enzyme

“…In today's global chemicals landscape, the focus is squarely on biomolecules like enzymes, renowned for their exceptional catalytic efficiency. Among them, proteases lead the way, comprising 60% of worldwide enzyme sales and finding utility in diverse industries spanning detergents, leather, textiles, food, and pharmaceuticals (Matkawala et al, 2022;Souza et al, 2022). Additionally, plant-derived enzymes such as papain, bromelain, and ficin have carved out their own place in various sectors, from meat tenderization to juice and beer clarification, cosmetics, textiles, baking, cheese production, edema treating, wool antishrinking, amino acid production and beyond (Shin et al, 2020;Benucci et al, 2020;Moreira Filho et al, 2020;Shouket et al, 2020).…”
