" good example of ingredientsused only in industrial settingsinclude specific sugars , such as dextrose , and protein sources , such as casein paint .
Ultraprocessing demand breaking down food into their portion parts , such as starches and oils . These are then chemically modified — to break bonds between their molecules , for instance — and combined with techniques like bump , which forces soft kernel together into a trust shape .
