Mechanistic insights into structural remodeling and functional enhancement of peanut protein induced by high-speed shear processing

Heat-induced structural and functional modification of peanut protein isolate for enhancing peanut butter quality and stability

Oil separation limits peanut butter quality and shelf life. This study investigated the effect of heat-induced aggregation of peanut protein isolate (PPI) at 60–100 °C on its structural, functional properties, and evaluated its application as a stabilizer in peanut butter. Thermal treatment altered PPI conformation—mos...

pH cycling-induced structural remodeling of walnut protein-whey protein isolate complex: Trade-off between digestibility and bioactivity.

The bioactivity of plant proteins is often limited by the compact and aggregated structures. In this study, the walnut protein-whey protein isolate (WP-WPIp) complex was constructed via pH cycling. This treatment appeared to induce conformational changes characterized by a disordering of secondary structures and a disr...

Laccase-induced structural remodeling of cottonseed protein for improving its emulsion stability and curcumin bioaccessibility.

BACKGROUND Cottonseed is an important byproduct of cottonseed processing and is rich in proteins. A literature review indicated that cottonseed protein isolate (CPI) demonstrated a compact structure because of its limited exposure of hydrophobic groups, leading to poor emulsifying performance. This limited the function...

Structural and functional modifications of soluble dietary fiber from pea fiber residues induced by extrusion-spray modification.

Pea fiber residue, a by-product of pea starch and protein extraction, is rich in dietary fiber, most of which is insoluble. An extrusion-spray (ES) modification was developed to increase the content of functionally valuable soluble dietary fiber (SDF). This technique used a reverse-threaded section in a twin-screw extr...

Processing and structural modifications of insect proteins for alternative proteins.

Multiscale structural modulation of plant proteins via ultrasound and electro-physical processing: from extraction to functional food matrices

The transition toward sustainable food systems has increased interest in plant proteins as alternatives to animal-derived proteins due to their lower environmental impact, including reduced greenhouse gas emissions, land use, and resource demand. However, their broader application is constrained by structural character...
