Modern Solutions for Better Behaved Dough
Plant-based doughs introduce complex rheological challenges that demand advanced ingredient solutions. Unlike traditional wheat-based doughs, which rely on gluten’s robust viscoelastic network for structure and gas retention, plant-based formulations—often derived from flours, proteins, and fibers like pea, soy, oat, or legume flours—tend to yield doughs that are prone to inconsistency, decreased elasticity, and rapid moisture loss. These factors can result in poor rise, dense crumb structure, dry mouthfeel, and shortened shelf-life.

These factors can result in poor rise, dense crumb structure, dry mouthfeel, and shortened shelf-life.
Central to resolving these issues are targeted enzyme systems that modify the biochemical and structural properties of dough. Enzymes such as proteases, amylases, xylanases, cellulases, lipases, and oxidases act as precision biocatalysts, transforming the protein–polysaccharide matrix into a more functional and flexible network. For instance, proteases carefully degrade select proteins in plant-based blends to enhance extensibility and dough machinability, while α-amylases convert starch into fermentable sugars, improving fermentation and crumb softness.
Scientific studies further highlight the synergistic benefits of enzyme combinations. In doughs enriched with oat bran, blends of α-amylase, xylanase, and cellulase were shown to decrease development time and enhance extensibility and stickiness, attributes critical for cohesive and pliable dough. Similarly, in bean-enriched wheat doughs, transglutaminase and glucose oxidase improved alveograph parameters and overall rheological behaviour, resulting in higher loaf height and improved crumb structure.
Recently, protease and lipase treatments have been experimentally applied to wheat and gluten-free doughs, enhancing hydration, softness, and texture—particularly in cookie and cake systems. Such tailored enzyme strategies are essential for plant-based bakes, where the absence of gluten presents gaps in structure, moisture retention, and texture.
Beyond texture, enzymes contribute to freshness. Maltogenic amylases delay staling, while xylanases and cellulases promote moisture retention and crumb softness—vital for extending shelf life in vegan and plant-based crackers, breads, and muffins. In addition, lipases and oxidases refine texture and dough stability during proofing.
