This study investigated the effects of walnut phenolics and extraction methods on the composition and structural properties of walnut protein isolates (WPIs). Fluorescence quenching experiments showed that walnut phenolics could bind to walnut globulins, albumins, and glutelins with apparent affinity constants of 5.49 × 104 M-1, 1.71 × 104 M-1, and 3 ...

This study focused on the interaction of walnut protein with phenolic extracts of walnut pellicle (PEWP) under alkaline condition, leading to enhancement of protein solubility under neutral condition. First, the change of PEWP under alkaline condition was determined by RP-HPLC and mass spectrometry, and the results showed that most ellagitannins in ...

Low-sugar and high-protein adhesives have broad market application prospects, while natural plant proteins have confronted technical bottlenecks due to their poor adhesion. In this study, the effects of ethanol with different concentrations (0-80%) on the adhesion properties of walnut protein isolate-xanthan gum (WNPI-XG) composite adhesives were ...

Whey protein edible films modified with almond and walnut oils
Food Hydrocolloids, 2016Abstract Whey protein isolate films with almond or walnut oils at low concentrations (0.5 and 1.0%) were prepared through emulsification in order to modify the functional properties of the films. Optical (colour and opacity), mechanical (tensile strength, Young's modulus, and elongation at break), barrier (water vapour, oxygen, and carbon dioxide ...

Simulated gastrointestinal digestion of walnut protein yields anti-inflammatory peptides
Food ChemistryThe impact of the simulated gastrointestinal digestion process on walnut protein and the potential anti-inflammatory properties of its metabolites was studied. Structural changes induced by digestion, notably in α-Helix, β-Turn, and Random Coil configurations, were unveiled. Proteins over 10,000 Da significantly decreased by 35.6 %.

Walnut oils were obtained by supercritical carbon dioxide extraction (SCB), cold-pressing (CP), hexane extraction (HE), and subcritical butane extraction (SBE), and walnut protein isolates (WPI) from the walnut cakes were performed. The results indicate that SCB has the highest oil yield for walnut oil, which was 62.72%, and the total content of trace ...

The walnut meal is rich in nutrients such as protein from the kernel and polyphenolic compounds from the seed coat. However, the influences of seed coat polyphenols on walnut protein (WP) hydrolysis remained unclear. In this study, our findings indicated that polyphenols induced alterations in the secondary structure and amino acid composition of WP ...

Electrospray Production of Curcumin-walnut Protein Nanoparticles
Food Biophysics, 2020Electrospray technique was applied to produce nanoparticles (NPs) from walnut protein isolate (WPI) in order to encapsulate curcumin. The optimized condition for the production of the WPI NPs was WPI concentration of 3.5%, a solvent mixture of deionized water: 2-propanol (2:1, v/v), electrospraying at a fixed distance, voltage and flow rate including ...
