是什么让海绵蛋糕中的打发蛋泡保持稳定？

Pastry, Cakes & Desserts

Research points to a heat-resistant egg-white protein network around small air bubbles. In sponge cakes, stability is helped by stronger bubble walls, higher resistance to deformation, and enough viscosity to slow liquid drainage. Sugar can improve egg-white foam stability, while egg-yolk components may either help retain whipped-in air or interfere with foaming, depending on the lipoprotein.

When egg whites are whipped, their proteins gather at the air–water surface and form elastic films around bubbles. Studies of egg-white foams and angel food cakes describe smaller, more stable bubbles and a protein network that develops during heating, helping the foam survive baking. Sugar improved the stability of egg-white foams in one study, apparently by changing the bubble-surface properties rather than simply making the mixture thicker. Egg yolk has mixed effects: one yolk lipoprotein was described as helping aeration, while another helped retain air whipped in by other egg components. The research is useful for understanding sponge-cake foam, but it does not establish one universal stabilizing mechanism for every recipe.

What this answer does not cover

• This synthesis uses titles and abstracts, not a full-text systematic review.
• Bibliographic index coverage and metadata can be incomplete or delayed.
• Retraction and publication-status metadata can be incomplete across connected indexes.
• Paper quality and risk of bias were not independently assessed.
• The synthesis is based only on the supplied study abstracts, not full papers.
• The studies used related but varied systems, including fatless sponge cakes, angel food cakes, wet protein foams, whipped sweets, and isolated egg-white or yolk components.
• The effects of sugar, yolk components, heating, and processing conditions were not identical across studies.
• One listed thesis record provides no substantive abstract, so its contribution cannot be evaluated in detail.
