Abstract:
In this study, peanut hulls powder (PHP) was treated via mechanical activation (MA) and divided into three groups (control, PHP150 and PHP250). Physicochemical properties including mean particle size distribution (MPSD), powder properties, solubility and in vitro protein digestibility of PHP were then investigated. The results showed that MA could decrease the particle size of PHP by destroying its crystal structure, resulting in an increase of amorphization and a decrease of crystallinity and crystalline size. The results of in vitro protein digestibility and crude fiber contents showed that MA increased the protein digestibility of PHP by 43.32% and 74.70% (P < 0.05), while crude fiber content was decreased by 0.42% and 26.65% (P < 0.05). These findings indicated a large application potential of MA in PHP treatment.

Mechanical and Chemical Digestion in the Small Intestine
Mechanical digestion in the small intestine involves movements such as segmentations and migrating motility complexes (MMCs), primarily controlled by the myenteric plexus. Segmentations are localized contractions occurring in areas of the intestine distended by chyme—a mixture of partially digested food. These contractions mix chyme with digestive juices, facilitating...
