Recent development on recovering bioactive peptides and phenolic compounds from under‐utilised by‐products during production of certain edible oil plants: current situation and future perspectives

Abstract

During the edible oil production process, massive amounts of by-products are generated each year that are not efficiently utilised, posing economic and environmental challenges. Under-utilised products derived from valuable oil-plants such as oil-extracted wheat germ, oil-extracted moringa seed, oil-extracted walnut and flaxseed meal will be increased, and new integration concepts will be required as soon as possible. These underutilised products can be rich sources of phenolic compounds and bioactive peptides with appropriate health-promoting properties such as anti-diabetic, antioxidant, anti-hypertensive, antiinflammatory, anticancer and antibacterial properties, according to this review. The recovery of bioactive compounds from these by-products can go a long way toward ensuring a sustainable food supply. Current challenges and requirements for recovering bioactive peptides and phenolic compounds from underutilised products derived from valuable oil-plants as well as the relationship between their biological activity and structure are discussed in this study.

Bioactive Antimicrobial Peptides from Food Proteins: Perspectives and Challenges for Controlling Foodborne Pathogens

“…Chromatographic methods are usually employed for purification, including size-exclusion chromatography, ion-exchange chromatography, and reversed-phase high-performance liquid chromatography. In addition, for identification and characterization of BAP sequences, liquid chromatography has usually been combined with mass spectrometry with ionization methods (e.g., electrospray ionization [ESI] and matrix-assisted laser desorption/ionization [MALDI]) [ 40 , 41 ].…”

“…As many pulses, such as soybean and peanuts, are used for edible-oil extraction, there is a massive generation of protein-rich by-products, which can be used for bioactive compound recovery, including BAPs [ 40 ]. For instance, high content of proteins of low molecular weight and of peptides can be found in maize nixtamalization wastewater (known as nejayote), which has shown potential anti-inflammatory activity [ 61 ].…”

The effect of date (Phoenix dactylifera L.) varieties on bioactive compounds, phenolic constituents, fatty acids and element contents of date seed and oils

“…Date varieties are effective on the quantity and properties of date seed oils containing medium level of the oil. In addition, the antioxidant phenolic constituents in it increase the beneficial properties of this oil (Mohd Jaih et al ., 2019; Karami & Duangmal, 2022; Zhang et al ., 2023). Phenolic compounds, which can be found in the form of glycosides and aglycones in plant tissues, give colour, taste and aroma to foods (Babiker et al ., 2020; Oluwole et al ., 2022; Chen et al ., 2023).…”
