Which egg substitutes work for binding versus leavening?

Ingredients & Substitutions

For binding, rice-protein ingredients—especially rice protein hydrolysates—are the best-supported option in the supplied evidence: they maintained functional properties, texture, and flavor in flaky egg rolls, although the abstract does not directly test binding strength. For leavening, use a gas-producing system rather than an egg substitute: baking powder combines an acid with sodium bicarbonate, while yeast or selected lactic-acid bacteria can raise dough through fermentation.

The evidence separates two functions. Rice protein hydrolysates are described as an egg replacement that preserved food functionality and texture, so they may help provide structure or binding, but this specific role is inferred rather than directly measured in the abstract. Leavening is addressed more directly by chemical systems such as baking powder, and by microorganisms such as baker’s yeast, Zymomonas mobilis, or certain lactic-acid bacteria. These leavening options provide gas or fermentation-related dough expansion; they should not be assumed to replace egg binding.

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 supplied studies do not directly compare common egg substitutes such as flaxseed, chia, aquafaba, starch, or commercial egg-replacer blends.
• The rice-protein study reports overall functionality, texture, and acceptability rather than a specific binding test.
• The leavening papers concern baking systems or microorganisms, not direct egg-for-egg substitution experiments.
• All conclusions are based only on supplied abstracts, not full-text methods or results.
