“…It is reported that hydrolysates can exert binding activity towards different minerals such as calcium , Huang et al, 2011, iron (Chaud et al, 2002;Lee and Song, 2009a), copper (Eckert et al, 2014), and zinc (Eckert et al, 2014). Different molecular sizes of the mineral binding peptides ranging from 1 to 1.5 kDa have been reported ( …”

Production of peptides with various effects from proteins of different sources continues to receive academic attention. Researchers of different disciplines are putting increasing efforts to produce bioactive and functional peptides from different sources such as plants, animals, and food industry by-products. The aim of this review is to introduce production methods of hydrolysates and peptides and provide a comprehensive overview of their bioactivity in terms of their effects on immune, cardiovascular, nervous, and gastrointestinal systems. Moreover, functional and antioxidant properties of hydrolysates and isolated peptides are reviewed. Finally, industrial and commercial applications of bioactive peptides including their use in nutrition and production of pharmaceuticals and nutraceuticals are discussed.

“…The solubility of the peptide fractions-zinc complexes was determined according to the literature with some modifications [16]. Diverse pH conditions were generated using appropriate buffers at 0.1 mol/L (KCl-HCl and citric acid phosphate buffer solution).…”

“…Furthermore, the molecular weight of hydrolysate fraction decreases with the increase of DH under certain hydrolysis conditions and it indicated that low molecular weight peptide fraction with higher DH exhibited the higher surface charge. The surface charge of the peptides was conducive to the stability of the particles except when the particle size could not be balanced with electrostatic repulsion [16,21,22]. The low molecular weight peptide fraction P1 exhibited the strong zinc chelation capacity, this can be due to the high electrostatic repulsion at P1 surface, reflected by high magnitude zeta potential, which inhibit intermolecular aggregation leading to small peptide particles.…”

Effect of Molecular Weight of Tilapia (Oreochromis Niloticus) Skin Collagen Peptide Fractions on Zinc-Chelating Capacity and Bioaccessibility of the Zinc-Peptide Fractions Complexes in Vitro Digestion

To investigate the effect of the molecular weight of tilapia skin collagen peptide fractions on their zinc chelation capacity and the bioaccessibility of their zinc complexes, we evaluated the zinc-chelating ability of different molecular weight peptide, the solubility, and the stability of the complexes during simulated in vitro digestion. Low molecular weight peptide (P1) exhibited a higher zinc-chelating ability, which can be attributed to the variety of metal chelate amino acid residues. The highest solubility and the lowest release of zinc during peptic digestion for the P1-zinc complex and the zinc binding to P1 were retained at approximately 50% after peptic-pancreatic digestion. Fourier transform infrared spectroscopy indicated the primary involvement of the N-H group in all peptide-zinc complexes. This finding suggests that low molecular weight peptidefraction with strong zinc chelation ability can be used as delivery agents to improve zinc bioaccessibility.

“…() highlighted the importance of this requirement. The affinity for binding between the protein (or peptide) and the mineral must be able to protect the mineral during the initial stages of digestion but also be low enough to allow for suitable release in the lower digestive tract (jejunum and duodenum) (Eckert, Bamdad, & Chen, ). While it has been suggested that unique transcellular pathway(s) may be available for some chelated minerals, none of these pathways have yet been identified or characterized (Cosentino et al., ; Hou et al., ).…”

This review aims to examine the relationship between the consumption of dairy products, mineral absorption, and bone health, and critically evaluates the methods that have been used to investigate this relationship. As people live longer and have lives that are more active in modern societies, bone health is of concern due to the possibility for the increasing incidence of bone disorders, such as osteoporosis. It has been suggested that dairy products can play a key role in bone health due to their high levels of minerals. Whether the positive effect of dairy consumption on bone health is due solely to the concentration of minerals, the action of vitamins, proteins, and lipids present in dairy products, and complex interactions between different milk components remains to be determined. Assessment of how dairy products affect bone health is complex, with apparent contradictory conclusions being reported in the literature. To gain a better understanding of the effects that dairy products have on bone health, this review presents an evaluation of a combination of data obtained using a variety of methods. From those data, we surmise that the preferable approach to investigate the effects of milk on bone health is to obtain data from human, animal, and cell line testing. A combined approach will enable various aspects to be identified, including mechanisms and the assessment of holistic effects, which will enable the effects in the human situation to be ascertained.
