Description
A protein restructuring technique that creates edible containers from denatured soy proteins.
Technical
Tofu skin (yuba) undergoes partial protein unfolding during production, allowing it to be reshaped when rehydrated. The folded structure is stabilized by hydrogen bonds between soy glycinin and β-conglycinin proteins during cooking.
Culinary Significance
Creates portion-controlled vessels that absorb braising liquids while maintaining structural integrity, used for both vegetarian and meat fillings.
