where does the name digestive biscuit come from
McVitie's McVitie & Price's first major biscuit was the McVitie's Digestive, created in 1892 by a new young employee at the company named Alexander Grant.[7] The biscuit was given its name because it was thought that its high baking soda content served as an aid to food digestion.[7] Grant was later to become managing director of the company, in 1923 he was the main benefactor in the establishing the National Library of Scotland giving an endowment of £100,000. Grant donated a further £100,000 in 1928 to assist with the building of the National Library premises on George IV Bridge in Edinburgh.[8]
Chyme After hours of mechanical and chemical digestion, food has been reduced into chyme. As particles of food become small enough, they are passed out of the stomach at regular intervals into the small intestine, which stimulates the pancreas to release fluid containing a high concentration of bicarbonate. This fluid neutralizes the gastric juices, which can damage the lining of the intestine, resulting in duodenal ulcer. Other secretions from the pancreas, gallbladder, liver, and glands in the intestinal wall help in digestion.
