Electrospray Production of Curcumin-walnut Protein Nanoparticles

Food Biophysics, 2020
Electrospray 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 ...

Identification and implication of an allergenic PR‐10 protein from walnut in birch pollen associated walnut allergy

Molecular Nutrition & Food Research, 2017
ScopeEnglish walnut (Juglans regia) belongs to the most important allergenic tree nuts. Co‐sensitization with birch (Betula verrucosa) pollen has been reported. We aimed to identify a walnut allergen homologous to the major birch pollen allergen Bet v 1.Methods and resultsA cDNA encoding a Bet v 1‐homologous allergen (Jug r 5) in walnut kernels was ...

Modulation of walnut protein solubility: effects of multiple modification treatments on walnut protein structure, physicochemical properties, and investigation of mechanisms

Food Research International
In this study, we proposed a targeted modification technique of ultrasound-assisted restriction enzyme digestion combined with glycosylation, which could significantly improve the solubility of walnut protein (WP, +91.63 %). The mechanism was elucidated by spectral analysis and molecular docking: ultrasound changed the conformation of WP to promote ...

Development of an indirect competitive immunoassay for walnut protein component in food

Food Chemistry, 2014
Among food allergens, walnut is a frequent cause of adverse food reactions in allergic patients. In this study, the walnut allergen protein 2S albumin precursor (Jug r 1) cDNA was synthesised and cloned into the pGEX-6P-1 expression vector. The recombinant plasmids were transformed into Escherichia coli (E.

Purification and Identification of an ACE Inhibitory Peptide from Walnut Protein

Journal of Agricultural and Food Chemistry, 2013
In the present study, a novel angiotensin I-converting enzyme (ACE)-inhibitory peptide, P-2a2, was purified to homogeneity from walnut protein hydrolysate by ultrafiltration, consecutive column chromatography, and high-performance liquid chromatography. The purified peptide was characterized by matrix-assisted laser desorption ionization time-of-flight

Quantitative indirect ELISA for determination of walnut proteins in foods

Food Science and Biotechnology, 2015
An indirect enzyme-linked immunosorbent assay (ELISA) capable of detecting walnut proteins in commercial products was developed. Polyclonal antibodies against soluble walnut protein were used. Specific epitopes of walnut protein were analyzed for cross activity with peanut, soybean, sesame, rice, wheat, jujube, and defatted milk protein.

Enzymolysis Optimization of Walnut Residue Protein Using Trypsase

Advanced Materials Research, 2013
The enzymolysis of walnut residue protein was investigated using trypsase, and the best process conditions were studied by one-factor experiment and orthogonal experiment. The result showed that the influential degree weakened as follows sequence: temperature, pH, enzyme quantity, and time.

Modulation of cecal microbiota and fecal metabolism in mice by walnut protein

Food & Function
The characteristic functional groups of WP exhibit obvious absorption peaks, with >30% α-helix and β-folding content in the secondary structure. WP is a typical spherical particle with a denaturation temperature of 73.6 °C, which indicates its good structural stability and thermal stability.
