Between the end of the 1700s and the beginning of the 1800s technological innovation appeared, such as bread maker machine or modern oven. At the beginning of the 1900s, bread was “black” and hard to chew because it was produced with wholegrain flours, rich in fibers. Later, technology permitted to refine the ingredients and white bread developed. Today, with the rediscovery of healthy food, it's used again wholegrain bread, rich in fibers.
