“…3A , with the extension of adsorption time, the F ratio of the solution showed the tendency of rises followed by drops, and the F ratio peaked at 2 h of adsorption. The adsorption with activated carbon is better under the acidic conditions, for hydrolytes have a lower solubility at acidic pH, which can facilitate the efficient adsorption of AAA onto activated carbon ( Jiang et al, 2017 ; Li et al., 2019 ). The results in this study showed that the maximum F ratio was reached at pH 2 ( Fig.…”

This study aimed to obtain high Fischer’s ratio oligopeptides from goat whey (HFO) and investigate antioxidant property of it. Hydrolysis of goat whey was done with the approach of sequential digestion of pepsin and flavourzyme. With the adsorption of aromatic amino acids by activated carbon, HFO with a Fischer’s ratio of 27.070 and a molecular weight of 200–1,000 Da were obtained, and the branched-chain amino acids accounted for 22.87%. Then the antioxidant activity of HFO was evaluated. At the concentrations of 2.0 mg/mL and 0.50 mg/mL, HFO scavenged 77.27% and 99.63% of 1,1-diphenyl-2-picrylhydrazyl and 3-ethylbenzthiazoline-6-sulphonate free radicals respectively. The scavenging rate of HFO against hydroxyl radicals reached 92.31% at the concentration of 0.25 mg/mL. Animal experiments demonstrated that HFO could moderate the changes of malondialdehyde, superoxide dismutase and glutathione peroxidase caused by CCl 4 -induced oxidative stress in vivo . This study indicated that HFO from goat whey was capable of oxidation resistance both in vivo and in vitro , which provided a scientific basis for the high-value processing and application of goat milk whey.

“…Thanks to the oligopeptide and the free amino acids having mutually independent absorption mechanisms, there will be no interference happen. Thus, the independent absorption mechanisms of oligopeptides and free amino acids prevent interference, reducing absorption inhibition and enhancing amino acid absorption in peptide forms, ultimately increasing protein synthesis efficiency (Jiang et al., 2017). Besides, FBPs can also promote the absorption and utilization of mineral elements (Cao et al., 2017).…”

Functional peptides constitute a class of small molecular peptide chains with specific functions in biology and are typically composed of various amino acids. The chemical‐synthesis methods for preparation of functional peptides can bring high toxicity to the human body. Therefore, there is a growing need to explore alternative, safter sources to obtain bioactive peptides. Food‐derived bioactive peptides (FBPs) stand out as an ideal substitution offering safety and accessibility that can be used in health products and pharmaceuticals to elicit their effects. Presently, the extraction, purification, functional properties, and bioavailability of FBPs have been poorly summarized. This review aims to address this gap by summarizing key aspects of FBPs, covering their source, methods of preparation, extraction, isolation, purification, and identification. Additionally, the review explores the functional characteristics and mechanism underlying FBPs. Emphasis is placed on strategies to enhance the stability and bioaccessibility of FBPs, crucial for their successful application in the food and medical industries. Existing research findings suggest that adopting appropriate methods can extract FBPs with high yield and purity. FBPs exhibit both in vitro and in vivo biological activities regulating relevant pathways, showcasing their potential in the medical field. In the quest for improved stability, the application of nanomaterials emerges as a promising strategy. These advancements collectively hint at a bright future for FBPs in both food and medical matrices. As the field progresses, further exploration and refinement of extraction techniques, functional properties, and bioavailability will contribute to unlocking the full potential of FBPs in various applications.

“…Li et al (2019) showed that, compared to particulate or columnar activated carbon, powdered activated carbon more effectively removed aromatic amino acids while retaining branched-chain amino acids. Moreover, aromatic amino acids are more effectively adsorbed by activated carbon at an acidic pH (Jiang et al, 2017). Chu et al (2012) used a 1:10 ratio of activated carbon to hydrolyzate for adsorption treatment, based on the removal rate of aromatic amino acids and the retention rate of branched chain amino acids.…”
