Phospholipids Raw Material
Bakery products (bread, cakes, pastries) often face issues like poor dough elasticity, uneven texture, and rapid staling. Phospholipids solve these problems by regulating the interaction between oil, water, and flour components.
-
Bread:
- Addition method: Mix 0.2%–0.6% phospholipids (based on flour weight) into the dough during the initial mixing stage, along with oil and water.
- Core roles:
- Emulsifies the oil-water mixture in dough, promoting the formation of a uniform gluten network—improving dough elasticity and reducing shrinkage during proofing.
- Inhibits starch retrogradation (the main cause of staling): By binding to starch molecules, it slows the recrystallization of amylopectin, extending the shelf life of bread by 2–3 days (e.g., from 3 days to 5–6 days under room temperature).
- Example: In whole-wheat bread, phospholipids reduce the "coarseness" caused by dietary fiber, making the crumb softer.
-
Cakes & Pastries:
- Addition method: Add 0.5%–1.0% phospholipids to the oil phase (e.g., butter, vegetable oil) before mixing with egg batter.
- Core roles:
- Enhances the emulsification of oil and egg liquid, preventing the batter from "separating" during baking—ensuring a smooth, fluffy texture (avoids dense or crumbly cakes).
- Reduces the amount of oil needed (by ~10%–15%) while maintaining moisture, making cakes lower in calories without compromising taste.
