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 ...

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 ...

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 ...

Antiproliferative Activity of Walnut ( Juglans regia L.) Proteins and Walnut Protein Hydrolysates
Journal of Medicinal Food, 2017Proteins from Juglans regia L. were isolated. Then, proteins were hydrolyzed with different enzymes. Antiproliferative activity of proteins and of the protein hydrolysates of J. regia L. were evaluated using the sulforhodamine B method. Glutelin and prolamin proteins presented a high antiproliferative activity against cancer cells PC-3 (prostate) and K-

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 ...

Effects of sonication on the physicochemical and functional properties of walnut protein isolate
Food Research International, 2018The objective of this study was to investigate the impact of high-intensity ultrasound treatment (sonication) on the molecular, physicochemical, and functional properties of walnut protein isolate. Aqueous walnut protein suspensions were sonicated at varying power levels (200, 400 or 600 W) and times (15 or 30 min), and then any alternations in protein
