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.
For recipes which use eggs primarily as a leavening agent you can try a commercial egg replacement product (see above) or the following mixture: 1-1/2 tablespoons vegetable oil mixed with 1-1/2 tablespoons water and 1 teaspoon baking powder per egg. Note: this mixture calls for baking powder, not baking soda.
