What are three disaccharides commonly found in foods?

1. Sucrose: This is the most common disaccharide, also known as table sugar. It's found in many natural sources, including sugarcane, sugar beets, and maple syrup, and is widely used in processed foods.

2. Lactose: This is the sugar found in milk and other dairy products. It's composed of glucose and galactose.

3. Maltose: This disaccharide is formed when starch breaks down, especially during the malting process used in brewing. It's found in products like malt beverages, candies, and some breakfast cereals.
