Retrogradation (starch)

Index Retrogradation (starch)

Retrogradation is a reaction that takes place when the amylose and amylopectin chains in cooked, gelatinized starch realign themselves as the cooked starch cools. [1]

Amylopectin

Amylopectin is a water-soluble polysaccharide and highly branched polymer of α-glucose units found in plants.

Amylose

Amylose is a polysaccharide made of α-D-glucose units, bonded to each other through α(1→4) glycosidic bonds.

Crystallization

Crystallization is the (natural or artificial) process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal.

Emulsion

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable).

Fat

Fat is one of the three main macronutrients, along with carbohydrate and protein.

Hydrogen bond

A hydrogen bond is a partially electrostatic attraction between a hydrogen (H) which is bound to a more electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), and another adjacent atom bearing a lone pair of electrons.

Modified starch

Modified starch, also called starch derivatives, are prepared by physically, enzymatically, or chemically treating native starch to change its properties.

Resistant starch

Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals.

Retrogradation

Retrogradation is the landward change in position of the front of a river delta with time.

Staling

Staling, or "going stale", is a chemical and physical process in bread and other foods that reduces their palatability.

Starch

Starch or amylum is a polymeric carbohydrate consisting of a large number of glucose units joined by glycosidic bonds.

Starch gelatinization

Starch gelatinization is a process of breaking down the intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water.

Syneresis (chemistry)

Syneresis (also spelled 'synæresis' or 'synaeresis'), in chemistry, is the extraction or expulsion of a liquid from a gel, as when serum drains from a contracting clot of blood.

Viscosity

The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress.
