📚 Quick Study Guide

  • 💧 Hydration's Role: Water is essential for life and plays a crucial role in cooking, affecting texture, flavor, and chemical reactions.
  • 🌡️ Boiling Point: Water boils at $100^{\circ}C$ (212°F) at sea level, decreasing at higher altitudes. This impacts cooking times.
  • 🧊 Freezing Point: Water freezes at $0^{\circ}C$ (32°F). Freezing can affect the texture of foods due to ice crystal formation.
  • ⚖️ Water Activity (aw): A measure of the free water in a food, ranging from 0 (bone dry) to 1 (pure water). It influences microbial growth and food preservation.
  • 🧫 Water and Microbes: High water activity promotes the growth of bacteria, yeast, and mold, leading to spoilage.
  • 🧪 Chemical Reactions: Water acts as a solvent, facilitating chemical reactions like hydrolysis and enzyme activity, essential in cooking processes.
  • 🍲 Cooking Methods: Different cooking methods (boiling, steaming, poaching) rely on water's properties to transfer heat and cook food.
