Eat like a Pig to Combat Obesity

METABOLITES, 13(3).

Is the intestinal mucous layer a natural deep eutectic solvent-based digestion matrix?

AMERICAN JOURNAL OF PHYSIOLOGY-GASTROINTESTINAL AND LIVER PHYSIOLOGY, 324(6), G438–G441.

By: T. Kempen n & G. Boerboom*

author keywords: digestion; eutectic; intestines; mucous layer; NADES
MeSH headings : Solvents; Deep Eutectic Solvents; Water; Starch; Digestion; Lipids; Plant Extracts / chemistry
TL;DR: It is proposed that the mucous layer in the small intestines harbors digestive enzymes like amylase, while starch, due to solubility, redistributes from the lumen into the mucOUS layer where it is subsequently digested by amyl enzyme. (via Semantic Scholar)

Pigs as recyclers for nutrients contained in Bermuda grass harvested from spray fields

BIORESOURCE TECHNOLOGY, 81(3), 233–239.

author keywords: Bermuda grass; swine; digestibility; enzyme; nutrient recovery
MeSH headings : Animal Feed; Animals; Conservation of Natural Resources; Digestion; Nitrogen; Poaceae; Swine
TL;DR: Results suggest that Bermuda grass digestibility is negative in animals not adapted to a high-fiber diet, and feeding Bermuda grass to pigs as a means to recycle nitrogen is thus not recommended. (via Semantic Scholar)

Stability of pepsin (EC 3.4.23.1) during in vitro protein digestibility assay

Qiao, Y. R., Gumpertz, M., & Van Kempen, T. (2002, September). JOURNAL OF FOOD BIOCHEMISTRY, Vol. 26, pp. 355–375.

By: Y. Qiao*, M. Gumpertz* & T. Van Kempen*

TL;DR: It was found that increase of pH and concentration of pepin increased pepsin's half-life for both specific activity decay and peptide bond hydrolysis, and the results indicated the time needed to maximize pepingin utilization depended on pH and the concentration. (via Semantic Scholar)
