Abstract:
... Delivering bioactive peptides orally is hampered by poor absorption across the gastrointestinal barrier. Using the walnut-derived peptide PW5, PPKNW, we explored whether coformulation of peptides with absorption enhancer sodium N-[8-(2-hydroxybenzoyl)aminocaprylate] (SNAC) could improve the intestinal absorption of orally-administered bioactive peptides. Herein, the application of SNAC enhanced th ...

In this study, chitosan and gum Arabic coacervated complex (CGCC) were used to stabilize high internal phase Pickering emulsion (HIPE), and cinnamon essential oil (CEO) was incorporated into oil phase. The effects of CEO and CGCC concentration on the microstructure, rheology, gel strength and stability of HIPE were investigated. Benefiting from the enhancement of the hydrophobicity of CGCC by gum ...

Abstract:
... The utilization of whey has become a challenge with the significant growth in the production of cheese and coagulated milk products. Consequently, we have developed cost-effective and waste-free production technologies for processing whey disposal into a variety of high-quality, value-added food products at the industrial level. This work constitutes a research on the impact of various alcoholic f ...

Abstract:
... Corn gluten meal is a by-product of corn starch production. To extend its application in the food industry, the extrusion of corn gluten meal was conducted, and the effects of temperature (80, 100, 120, and 140 °C) on physicochemical properties and protein structure of the extrudates were investigated. Corn gluten meal was texturized when the extrusion temperature reached 120 °C, and puffed when i ...
... To improve the sustainable antibacterial active of nisin, nisin-loaded carboxymethyl chitosan (CMCS-nisin) nanogels (CN NGs) are prepared via a combination method of electrostatic self-assembly and chemical cross-linking. The as-prepared CN NGs are profiled using dynamic light scattering, zeta potential, transmission electron microscopy, fourier transform infrared spectroscopy (FT-IR) and X-ray ph ...

Abstract:
... We show that colloidal suspensions that acquire a surface charge by capturing ions from the surrounding solution display unexpected and remarkable phoretic behavior. Depending on suspension volume fraction, a critical zeta potential ζ exists where the effective electrophoretic mobility diverges, becoming virtually infinite. Beyond such critical value, a ζ-range is identified where mobility reversa ...

Abstract:
... The traditional model of the Isolated Double Layer (DL) becomes inadequate in concentrated dispersions when the distance between particles becomes comparable to the Debye length and DLs overlap. The notion of “overlapping DLs” was introduced to Electrophoretic theory 60 years ago by Prof. T. Overbeek’s group. The theory posed in that paper and a subsequent publication by Long and Ross predicts a d ...
