It amazes me how store-bought bread can last for months because the bread that I make is only edible for a few days. Food manufacturers have to add chemicals to keep bread fresh, and I'm sure only the cheapest flour is used. Today, I read an article about some of the ingredients in packaged foods. It made me glad to know my bread doesn't contain hair or duck feathers. Well, it might contain some of my hair but that's ok :)
Here is the excerpt:
"Many packaged breads and baked goods contain L-cysteine—a non-essential amino acid made from dissolved human hair (often from China) or duck feathers (mmmm). Food manufacturers use the ingredient as a commercial dough conditioner, meant to improve the texture of breads and baked goods."
