Theoretical Framework (Main Concept) Crystallization is a physical process in which a substance changes from a dissolved state into solid crystals. In baking, this mainly occurs with sucrose (table sugar), affecting the texture of products such as candies, syrups, and caramel. Glucose is a simple sugar that, when added to sucrose mixtures, acts as a crystallization inhibitor. This happens because glucose molecules interfere with the organization of sucrose molecules, preventing them from arranging in an orderly structure to form crystals. Additionally, glucose acts as a plasticizer, meaning it helps the mixture become more flexible, smooth, and less brittle, improving the final texture of the product. This is considered a physical change, since the chemical composition of the substances does not change, only their structure and behavior. ⸻ 2. Hypothesis If glucose is added to a sucrose solution, then crystal formation will decrease or be delayed, because glucose interferes with the molecular organization of sucrose, preventing its recrystallization and modifying the final texture. ⸻ 3. Materials * Sugar (sucrose) * Glucose syrup or honey (source of glucose) * Water * Stove or hot plate * Pot or saucepan * Stirring spoon * Thermometer (optional but recommended) * Transparent containers * Molds or cooling surfaces * Labels ⸻ 4. Procedure 1. Preparation of solutions: * Prepare two mixtures: * Mixture A: water + sucrose * Mixture B: water + sucrose + glucose 2. Heating: * Heat both mixtures over medium heat, stirring until the sugar completely dissolves. 3. Cooking: * Continue heating until both mixtures reach a syrup-like consistency. 4. Cooling: * Pour each mixture into separate containers. * Let them cool at room temperature without stirring. 5. Observation: * Analyze crystal formation in each sample. * Compare texture, appearance, and consistency. 6. Recording results: * Write down differences (time of crystallization, crystal size, texture). ⸻ 5. Expected Results It is expected that: * The mixture without glucose will form crystals more quickly. * The mixture with glucose will have a smoother, less crystalline texture. * Glucose will inhibit the recrystallization of sucrose. ⸻
