Description
Enzymatic breakdown of pectin in plant cell walls creates tender textures without heat degradation.
Technical
Pectinase (polygalacturonase) hydrolyzes α-1,4-glycosidic bonds in pectin polymers, while pectinesterase removes methyl groups from pectin methoxyl esters, collectively destabilizing the middle lamella between cells.
Culinary Significance
Enables precise control over vegetable texture, creating novel mouthfeels while preserving raw flavors and nutrients.
