Aquafaba as a Sustainable and Plant-Based Egg Alternative: Recent Advances in Extraction, Nutritional Insights, and Functional Characterization
摘要
Aquafaba, the aqueous by-product of legume cooking, has gained prominence as a sustainable, plant-based egg alternative due to its exceptional foaming, emulsifying, and moderate thickening ability. This review explores the recent advancements from 2017 to 2025 in aquafaba extraction and processing, highlighting how legume type, pre-treatment, and cooking influence aquafaba’s functional performance. The impact of storage conditions and stability on aquafaba’s physicochemical attributes, along with its comparative performance against conventional egg and plant-based alternatives, is analyzed. Despite its promising application, challenges such as batch variability, lack of standardization, and sensory drawbacks hinder its large-scale commercialization. Addressing these issues through improved processing techniques and technological innovations could enhance its consistency and functionality. Additionally, the role of aquafaba in waste valorization and sustainability is examined, underscoring its alignment with circular economy principles and food systems. With increasing consumer demand for sustainable, clean-label, and egg-free ingredient formulations, aquafaba represents a compelling opportunity for innovation in plant-based product development.
