Chemical reactions are really important in cooking and keeping food fresh. Let’s look at a couple of examples:

1. Cooking:

   • Maillard Reaction: This happens when amino acids and sugars mix together. It creates the tasty brown color and flavor we love in foods like a nicely cooked steak!

2. Preservation:

   • Fermentation: This is when sugars change into acids, gases, or alcohol. This process helps keep foods like yogurt and sauerkraut fresh for a longer time.

These reactions not only make our food taste better but also help it last longer. That's why they are so important in our kitchens!
