Summary: Food bioactive peptides are widely used in food products and functional biomaterials, but their practical applications are limited due to their instability and low bioavailability. In this study, the self-assembling peptide RADA16 was functionalized with two synthetic analogues of food bioactive peptides to improve their nanostructures and biological features. The co-assembly of the functionalized food bioactive peptides with RADA16 was found to enhance their bioactivity and potential for the prevention of metabolic syndrome.

Summary: This paper reviews the production, identification, and structure-activity relationships of DPP-IV inhibitory peptides, and discusses their bioavailability and hypoglycemic effects. The bioinformatics approach is found to be more convenient and efficient in identifying peptides with DPP-IV inhibitory activity. Peptides with proline or alanine residue at the second position of the N-terminal exhibit strong DPP-IV inhibitory activity. The bioavailability of these peptides is related to their gastrointestinal stability and cellular permeability, and in vivo studies show improved glucose homeostasis. Additionally, innovative summaries of intestinal transport of DPP-IV inhibitory peptides and cell biological assays for evaluating their potential role in glycemic regulation are provided.

Summary: In this study, different enzymes and simulated digestion were used to investigate the DPP-IV inhibitory activities of oat protein hydrolysates. Neutrase was found to produce oat protein hydrolysate with the most potent DPP-IV inhibitory property, and ten new DPP-IV inhibitory peptides were identified. Molecular docking experiments further confirmed the interaction between these peptides and DPP-IV. Therefore, oat could be a promising source of dietary supplement for type 2 diabetes mellitus (T2DM).

Summary: Parameters such as choice of enzyme, reaction pH, and drying process have an impact on the physicochemical and biofunctional properties of whey protein hydrolysates (WPHs) generated by enzymatic hydrolysis. Spray-dried (SD) WPHs have spherical particles, higher moisture content, and higher antioxidative properties compared to freeze-dried (FD) WPHs. Both hydrolysis and drying processes affect the biofunctional activity of WPHs.

Summary: This study investigated the physicochemical properties of hydrolysates generated from different protein sources using two enzymes. The degree of hydrolysis increased with incubation time, and the hydrolysis with Debitrase HYW20 (TM) resulted in higher levels of small peptides compared to Prolyve (TM). The effect of hydrolysis on physicochemical properties varied depending on the substrate and the heat inactivation step had an impact on the physical properties of the hydrolysates.

Summary: Large quantities of mussel byssus, a fibrous material rich in collagen, are generated as a byproduct of the mussel-processing industry. Extracting collagen from this material using food-friendly strategies has been challenging due to its complex structure. In this study, an enzyme-aided method was employed to extract collagen from mussel byssus, resulting in a yield of 138.82 +/- 2.25 mg collagen/g dry weight. The enzymatic hydrolysates of the extracted collagen showed significant hydrolysis and exhibited high in vitro bioactivities. These findings suggest that mussel byssus collagen-derived hydrolysates have potential applications as functional food ingredients for the management of metabolic diseases.

The results showed that enzymatic hydrolysis increased the wettability and solubility of the hydrolysates, as well as their moisture content, while reducing their stability. It is suggested that the manufacture of hydrolysate ingredients with controlled moisture content and storage at controlled ambient temperatures can maintain the improved rehydration properties.

Summary: The development of green and sustainable biotechnological approaches for preventing chill haze formation is being investigated. In this study, the use of laccase and tannase enzymes effectively removed haze active phenols and prevented chill haze formation during brewing. Tannase-based treatment in the post-mashing step completely removed HA phenols, while dosages of tannase before yeast inoculum showed dosage-dependent effectiveness in reducing HA phenols and preventing chill haze.
