Such findings suggest that the strategic incorporation of YPI and RPI enables precise tuning of the SPI-based HMMA texture, providing a novel approach to optimizing plant-based meat structures through targeted protein selection and extrusion processing.

Herein, the effect of different pre-freezing temperature (−20 °C (A20), −80 °C (A80), and −196 °C (A196)) on structural and functional properties of single-component SPI aerogels is investigated. The single-component SPI aerogels are prepared by transglutaminase (TGase)-crosslinked SPI hydrogels as precursors and then pre-frozen at different temperatures.

In contrast, A196 demonstrates the most compact microstructure and the most concentrated pore size distribution, with the lowest porosity of 90.43 ± 0.28 %. Importantly, the pre-freezing treatment significantly influences the structural properties of SPI aerogels. A196 aerogel shows less ordered structures, with a higher presence of β-turns and random coils, compared to the more ordered structures observed in A20 and A80 aerogels. Moreover, A196 aerogel exhibits the best oil adsorption capacity (OAC) and oil holding capacity (OHC), while A80 aerogel demonstrates the highest dye adsorption.

In this study, a calcium depleted β-CN was prepared from micellar casein isolate by cold microfiltration. Partial dephosphorylation was carried out using alkaline phosphatase and quantified though intact protein analysis by LC-MS. In situ self-association was investigated during heating (15–75 °C, 1 °C increments) in a multichannel spectrophotometer, with absorbance and static light scattering (SLS) being monitored. An experimental design was employed to investigate the impact of calcium concentration (0–9 mM), β-CN concentration (2.5–10 mg/mL) and degree of dephosphorylation. The results demonstrate that altering the calcium concentration has a significant impact on tuning of the temperature-induced self-association of β-CN. Notably, at 0 mM calcium, irreversible self-association was not observed, and increasing calcium concentration led to a decrease in the temperature of initial self-association. Partial dephosphorylation also had a significant impact, resulting in an increased temperature at initial self-association. The calcium to β-CN ratio exerted a significant impact on the self-association temperature, while the β-CN concentration alone had no pronounced effect. Furthermore, it was demonstrated that calcium-phosphate bridges were not solely responsible for the self-association protein interactions of partially dephosphorylated β-CN.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"170 ","pages":"Article 111668"},"PeriodicalIF":11.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144500914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through acid-heat induction, this study successfully converted soy protein isolate (SPI) into SPF and systematically investigated the gelation mechanism of riboflavin (RF)/UV-induced SPF photo-crosslinked hydrogels. The results demonstrated that RF actively participated in the crosslinking reaction, and fibrillar modification significantly improved the binding ability of SPI with RF. Isothermal titration calorimetry (ITC) revealed that fibrillar modification altered the thermodynamics of the SPI/RF binding, shifting the reaction from endothermic to exothermic, with the binding driving force transitioning from hydrophobic interactions to hydrogen bonding. After UV irradiation at a riboflavin concentration of 0.5 mM, both SPI and SPF samples exhibited optimal rheological properties. Notably, the SPF/RF system was able to stably form a gel, with its storage modulus increasing by 74-fold and 25-fold compared to the SPI/RF system and the native SPF sample, respectively. This enhancement indicates the formation of a more continuous three-dimensional network structure, wherein riboflavin functions as a photocatalyst.

However, the application process faces great challenges, such as slow fibrillation processes and low conversion efficiency. The effects of ultrasound and enzymolysis pretreatment on the conformation and physicochemical properties of pea protein fibrils (PPFs) during the lag, growth, and plateau phases were investigated, and a novel astaxanthin (AST) delivery system was developed. The results indicated that both ultrasound and enzymolysis pretreatment alters the fibrillation process by disrupting and reorganizing hydrophobic interactions, dityrosine covalent bonds, and disulfide bonds between molecules. Notably, ultrasound increased the flexibility, surface hydrophobicity, and dispersibility of pea proteins, resulting in forming PPFs with a smaller scale (130.57 nm–185.27 nm). Enzymolysis pretreatment significantly shortened the hydrolysis time of pea protein and increased the β-sheet proportion (41.4 %) of PPFs, thereby promoting the formation of more and larger scale PPFs (412.27 nm–838.47 nm) through molecular folding and aggregation of more fibril building blocks. Among these, albumins (<17 kDa) were the primary subunits of PPFs at the plateau phase. Furthermore, the encapsulation of AST by PPFs resulted in the formation of amorphous complexes, which enhanced the functional properties of AST. In particular, the PPF/AST complex under ultrasonic co-enzymolysis pretreatment exhibited the highest DPPH radical scavenging activity (56.35 %), ABTS radical scavenging activity (62.22 %), AST retention (50.15 %), and bio-accessibility (37.64 %).
