摘要

椰子粉球蛋白具有一定的乳化特性。然而,球蛋白对导致蛋白质变性和聚集的环境因素敏感,限制了其应用。在本工作中,利用ph移位结合超声对球蛋白进行改性,以改善其结构和乳化性能。结果表明,ph位移联合超声处理导致内部隐藏的疏水残基暴露,氢键破坏。随着荧光强度的提高,球蛋白的表面疏水性和分子柔韧性增强。复合处理条件显著提高了球蛋白基乳剂的界面蛋白吸附量。所得乳剂分散均匀,无聚集,具有最佳的储存、热稳定性和冷藏稳定性,与酪蛋白酸钠的性能相似。该研究为开发植物蛋白作为高价值乳化剂提供了有效的策略,为可持续食品配方提供了潜在的替代方案。

Influence of pH-shifting combined with ultrasound on the structure and emulsification characteristics of coconut meal globulin.

Coconut meal globulin exhibited certain emulsifying properties. However, globulin was sensitive to environmental factors that lead to protein denaturation and aggregation, thus limiting their application. In the current work, globulin was modified using pH-shifting combined with ultrasound to improve the structural and emulsification properties. Results showed the pH-shifting combined with ultrasound treatment led to the exposure of internal hidden hydrophobic residues, disruption of hydrogen bonding. The surface hydrophobicity and molecular flexibility of globulin increased, along with improved fluorescence intensity. The combined treatment conditions boosted the interfacial protein adsorption content of globulin-based emulsions significantly. The resulting emulsions were uniformly dispersed without aggregation, exhibited optimal storage, thermal, and cold storage stability, similar to the performance of the sodium caseinate. This study provides an effective strategy for developing plant-based proteins as high-value emulsifiers, providing a potential alternative for sustainable food formulations.

期刊介绍: Ultrasonics Sonochemistry stands as a premier international journal dedicated to the publication of high-quality research articles primarily focusing on chemical reactions and reactors induced by ultrasonic waves, known as sonochemistry. Beyond chemical reactions, the journal also welcomes contributions related to cavitation-induced events and processing, including sonoluminescence, and the transformation of materials on chemical, physical, and biological levels. Since its inception in 1994, Ultrasonics Sonochemistry has consistently maintained a top ranking in the "Acoustics" category, reflecting its esteemed reputation in the field. The journal publishes exceptional papers covering various areas of ultrasonics and sonochemistry. Its contributions are highly regarded by both academia and industry stakeholders, demonstrating its relevance and impact in advancing research and innovation.
