Formulated according to product quality requirements to provide emulsification, thickening, stabilization, and protein protection for various protein beverages, while delivering a rich and smooth mouthfeel. The core mechanism involves thickening, emulsification, and steric hindrance to resolve issues such as protein aggregation/sedimentation, fat separation, and phase separation/watering-off. It also resists system disruption caused by pH fluctuations, high-temperature sterilization, and ionic interference. Its core value lies in maintaining product homogeneity and stability, preserving the natural flavor and smooth texture of protein beverages, extending shelf life, and adapting to different protein sources and processing requirements.
