/ˈæmɪləm/

Definitions

• A form of starch, especially that derived from plants, used as a carbohydrate source in the diet.
• The starch in its unmodified or raw form, typically found in tubers, seeds, and roots.
• A polysaccharide that serves as an energy storage molecule in plants.

Usage Examples

• The amylum content in potatoes makes them a significant source of energy in many diets.
• Amylum is broken down by amylase during digestion to release glucose for energy.
• Rice and maize are two common sources of amylum used in food production around the world.

Etymology

The word "amylum" comes from the Latin word "amylum," meaning starch, which is derived from the Greek word "ἄμυλον" (ámylon), meaning "starch" or "flour." The term has been used since the early 17th century to refer to starch in its pure, unmodified form.

Historical Usage

Amylum has been known and used for centuries, with its primary use being in food preparation and as an industrial product. Early references to starch in the ancient world, especially in Egypt and Greece, were often in relation to the use of plants like wheat and barley. The isolation and identification of amylum as a distinct substance took place in the 19th century, which led to its widespread application in food, textiles, and later in pharmaceuticals and bioplastics.

Cultural Nuances

In many cultures, amylum (starch) plays a key role in culinary traditions. In East Asia, rice starch is a staple, while in Europe, potatoes and corn are primary sources of starch. In various parts of the world, amylum is used to thicken soups and sauces, and in some countries, it serves as a base for traditional snacks and desserts. Its properties, like its ability to absorb water and thicken, make it a crucial ingredient in the preparation of food and beverages.

More Information

Amylum, or starch, is one of the most important polysaccharides found in plants. It serves as a storage form of glucose, which is used by plants for energy. In humans, amylum is a major source of carbohydrates, contributing to the daily intake of calories. The structure of amylum can vary based on its source, with some plants having higher amylose content (a form of starch that is less soluble in water) and others containing more amylopectin (a branched form of starch). The digestibility of amylum depends on these variations, affecting the glycemic index of foods rich in starch.
