Does a high-fat meal remain in the stomach longer then a high-carbohydrate meal?
Yes, crude protein and carb digestion begins in the stomach but is actually done by the duodenum. No fat digestion is done in the stomach. When high fat chyme is passed into the duodenum enzymes from the pancreas and bile from the gallbladder are needed to digest the fat. Therefore a signal is sent and inhibits the stomach from passing anymore chyme to the duodenum until fat digestion is complete. This is why high fat foods tend to stay in the stomach longer. ~simply the duodenum needs time to get bile and pancreatic enzymes to break down the fat. The standard for a high fat meal that the FDA uses for clinical studies is a McDonalds burger, fries and a soda!

Starch digestion begins in the mouth when amylase, an enzyme produced by the salivary glands, is secreted into the oral cavity. Amylase helps break down starch into smaller sugar molecules such as maltose.
Where does contact digestion take place?
The brush border of intestinal villi contains various Pep-tidase s. They brake down small Pep-tides into amine acids. Various Bi-sachharidases to spit Maltose, Sucrose and lactose sugars. (Maltese, Sucrase and Lactase are the enzymes.) Small quantity of intestinal lipase to split Fat into glycerol and Fatty acids. So this type of digestion is called as contact digestion and it takes place in small intestine.
