predigestion
Beforehand food processing
Predigestion is the partial breakdown of food before it reaches the stomach.
Some animals predigest food for their young by chewing it first.
In medicine and nutrition, predigested formulas have proteins or other components already broken down for easier absorption: The infant formula uses predigested proteins for babies with allergies.
