摘要

本研究旨在制作不同油分的皮克林乳液，并评估超声波处理对乳清蛋白分离物（WPI）特性的影响。在功率为 640 W、持续 30 分钟的条件下，超声波可减小乳清蛋白分离物的聚集尺寸，提高 zeta 电位，并改善发泡、乳化和持水能力。傅立叶变换红外分析显示结构发生了变化，同时荧光和疏水性增加，表明三级结构发生了改变。这表明超声能有效地改变 WPI 的功能。在理想条件下，φ = 80 的乳液最为稳定，没有起泡或相分离现象。激光扫描显示，φ = 80 时的乳液组织良好。这项研究为改性和利用 WPI 提供了参考。

Optimization and Preparation of Ultrasound-Treated Whey Protein Isolate Pickering Emulsions.

This study aimed to create Pickering emulsions with varying oil fractions and assess the impact of ultrasonic treatment on the properties of Whey Protein Isolates (WPIs). At 640 W for 30 min, ultrasound reduced WPI aggregate size, raised zeta potential, and improved foaming, emulsifying, and water-holding capacities. FTIR analysis showed structural changes, while fluorescence and hydrophobicity increased, indicating tertiary structure alterations. This suggests that sonication efficiently modifies WPI functionality. Under ideal conditions, φ = 80 emulsions were most stable, with no foaming or phase separation. Laser scanning revealed well-organized emulsions at φ = 80. This study provides a reference for modifying and utilizing WPI.

期刊介绍： Foods (ISSN 2304-8158) is an international, peer-reviewed scientific open access journal which provides an advanced forum for studies related to all aspects of food research. It publishes reviews, regular research papers and short communications. Our aim is to encourage scientists, researchers, and other food professionals to publish their experimental and theoretical results in as much detail as possible or share their knowledge with as much readers unlimitedly as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: manuscripts regarding research proposals and research ideas will be particularly welcomed electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material we also accept manuscripts communicating to a broader audience with regard to research projects financed with public funds
