Structural changes of wheat starch and activity inhibition of α-glucosidase by persimmon (Diospyros kaki Thunb.) leaves extract retarding starch digestibility.

Elevated blood sugar levels caused by starch digestion was a target for controlling diabetes mellitus. The in vitro and in vivo digestibility of wheat starch was evaluated to find that adding 15 % persimmon leaf extract (PLE) to starch reduced its digestibility by 69.50 % and the peak postprandial blood glucose by 23.

Immature persimmon residue as a novel biosorbent for efficient removal of Pb(II) and Cr(VI) from wastewater: Performance and mechanisms.

Owing to the powerful affinity of tannin toward heavy metal ions, it is frequently immobilized on adsorbents to enhance their adsorption properties. However, natural adsorbents containing tannin have been overlooked owing to its water solubility. Herein, a novel natural adsorbent based on the immature persimmon residue (IPR) with soluble tannin removed was fabricated to eliminate Pb(II) and Cr(VI) in aquatic environments.

Hypoglycemic activity of immature persimmon (Diospyros kaki Thunb.) extracts and its inhibition mechanism for α-amylase and α-glucosidase.

Persimmon tannins, particularly in immature persimmons, haven't yet received corresponding attention to research on therapy of diabetes mellitus in spite of high hypoglycemic activity. To accurately screening key hypoglycemic components, immature persimmon extracts were isolated and identified using enzyme affinity ultrafiltration and HRLC-ESI-MS/MS. Among them, Hederagenin (IC = 0.

Galactooligosaccharide Mediates NF-κB Pathway to Improve Intestinal Barrier Function and Intestinal Microbiota.

The use of antibiotics to treat diarrhea and other diseases early in life can lead to intestinal disorders in infants, which can cause a range of immune-related diseases. Intestinal microbiota diversity is closely related to dietary intake, with many oligosaccharides impacting intestinal microorganism structures and communities. Thus, oligosaccharide type and quantity are important for intestinal microbiota construction.

Changes of bacterial microbiota and volatile flavor compounds in ewe milk during dielectric barrier discharge cold plasma processing.

Dielectric barrier discharge cold plasma (DBD-CP) processing can be considered as a potential alternative to conventional pasteurization in ewe milk, which has previously been shown. However, residual microorganisms in ewe milk during DBD-CP processing have not yet been evaluated. This study investigated the microbiota present in ewe milk that was cold plasma-treated.

Using hyperspectral imaging technology for assessing internal quality parameters of persimmon fruits during the drying process.

The crucial features of persimmon are required to detect real-time moisture, water-soluble tannin, and soluble solids contents during the drying process. This study developed a method based on hyperspectral imaging (HSI) to execute online and non-destructive assaying of persimmon features. A total of 144 samples were collected, and 150 bands were scanned.

Number of galloyl moieties and molecular flexibility are both important in alpha-amylase inhibition by galloyl-based polyphenols.

The inhibition of porcine pancreatic α-amylase (PPA) by 9 galloyl-based polyphenols was evaluated via initial digestion velocity, IC, inhibition kinetics, fluorescence quenching and molecular docking studies. The results show that the polyphenols with free galloyl moieties (GMs) exhibited a much higher inhibition effect than that with bound GMs. The inhibition was competitive mode and increased with an increase in the number of free GMs.

Alterations in physicochemical and functional properties of buckwheat straw insoluble dietary fiber by alkaline hydrogen peroxide treatment.

To enhance the physicochemical and functional properties of insoluble dietary fiber (IDF) from buckwheat straw, we investigated the effects of alkaline hydrogen peroxide (AHP) treatment. Electron microscopy showed that the IDF had regular and compact tubes that turned into wrinkled lamellar products. After AHP treatment, X-ray diffraction indicated that the crystalline structure of the IDF was perturbed.

Vanillic acid alleviates palmitic acid-induced oxidative stress in human umbilical vein endothelial cells via Adenosine Monophosphate-Activated Protein Kinase signaling pathway.

Vanillic acid (VA), one of the phenolic acids metabolized by anthocyanidins, can modulate vascular reactivity by reducing the superoxide. We investigated that VA alleviated fatty acid-induced oxidative stress and clarified its potential mechanisms in human umbilical vein endothelial cells (HUVECs). Our results showed that VA reduced the production of reactive oxygen species and malondialdehyde levels.
