Crystallization is also a chemical solidâliquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering crystallization occurs in a crystallizer.
You might be wondering how flour is a vegan substitute. Besides it being a substitution for gluten-free recipes, chickpea flour can be a vegan substitution for eggs. I use chickpea flour to make omelets, crepes, quiche, and batter for French toast and tofu cutlets. Chickpea flour can also be an egg replacement in baking.
The mostly commonly used egg substitutes for cakes will be silken tofu, yogurt, pureed fruit, vinegar-baking soda (in certain recipes, strictly not for recipes which uses more than 1 egg). Personally I found a winning combination to substitute for eggs in cakes, which is a mix of yogurt and pureed silken tofu.
