In the United States, where ultra-processed foods make up 58 percent of the calories Americans consume, government experts arebetween ultra-processed foods and obesity, and their findings could influence the government’s influential Dietary Guidelines for Americans. These refined starches are often used to thicken and improve the “mouthfeel” of processed foods like puddings, sauces, salad dressings, canned soups, stews and baked goods. But they’re also used to make a variety of other ultra-processed foods through a manufacturing technique called extrusion cooking.
While the process can vary, the machine typically twists and heats the mixture, generating intense pressures, sheer forces and temperatures that melt the mixture. This process disrupts the food matrix of the starch: It breaks open the rigid cell walls inside the starch and destroys its microscopic granules, which contain long chains of glucose, a type of sugar.
