Abstract

This study investigates the variations in ultrasound power and temperature of ultrasound-assisted phosphorylation (UAP) on the functional and structural properties of fish gelatin (FG). The results indicate that UAP significantly enhances the gel strength, antioxidant activity, and emulsifying properties of FG. FTIR analysis reveals structural changes, indicating that increased degrees of phosphorylation are associated with characteristic vibrational bands. Mass spectrometry identified phosphorylation sites in fish gelatin, primarily serine (Ser) and threonine (Thr), while molecular docking further revealed the major binding sites of these sites to sodium pyrophosphate. The study establishes that controlled ultrasound treatment, when combined with phosphorylation effectively improves FG properties, making it suitable for applications in the food and pharmaceutical industries.

超声辅助磷酸化对鱼明胶功能和结构特性的影响

研究了超声辅助磷酸化（UAP）过程中超声功率和温度的变化对鱼明胶（FG）功能和结构特性的影响。结果表明，UAP能显著提高FG的凝胶强度、抗氧化活性和乳化性能。FTIR分析揭示了结构变化，表明磷酸化程度的增加与特征振动带有关。质谱分析鉴定了鱼明胶中的磷酸化位点，主要是丝氨酸（Ser）和苏氨酸（Thr），而分子对接进一步揭示了这些位点与焦磷酸钠的主要结合位点。该研究表明，控制超声处理与磷酸化相结合，可有效改善FG的性能，使其适用于食品和制药行业。

期刊介绍： Food Hydrocolloids publishes original and innovative research focused on the characterization, functional properties, and applications of hydrocolloid materials used in food products. These hydrocolloids, defined as polysaccharides and proteins of commercial importance, are added to control aspects such as texture, stability, rheology, and sensory properties. The research's primary emphasis should be on the hydrocolloids themselves, with thorough descriptions of their source, nature, and physicochemical characteristics. Manuscripts are expected to clearly outline specific aims and objectives, include a fundamental discussion of research findings at the molecular level, and address the significance of the results. Studies on hydrocolloids in complex formulations should concentrate on their overall properties and mechanisms of action, while simple formulation development studies may not be considered for publication. The main areas of interest are: -Chemical and physicochemical characterisation Thermal properties including glass transitions and conformational changes- Rheological properties including viscosity, viscoelastic properties and gelation behaviour- The influence on organoleptic properties- Interfacial properties including stabilisation of dispersions, emulsions and foams- Film forming properties with application to edible films and active packaging- Encapsulation and controlled release of active compounds- The influence on health including their role as dietary fibre- Manipulation of hydrocolloid structure and functionality through chemical, biochemical and physical processes- New hydrocolloids and hydrocolloid sources of commercial potential. The Journal also publishes Review articles that provide an overview of the latest developments in topics of specific interest to researchers in this field of activity.
