Hydroxyethyl starch (HES/HAES), sold under the brand name Voluven among others, is a nonionic starch derivative, used as a volume expander in intravenous therapy. The use of HES on critically ill patients is associated with an increased risk of death and kidney problems.
Modified starches are used in practically all starch applications, such as in food products as a thickening agent, stabilizer or emulsifier; in pharmaceuticals as a disintegrant; or as binder in coated paper. They are also used in many other applications. [2] Starches are modified to enhance their performance in different applications.
Damaged starch can be produced, for example, during the wheat milling process, or when drying the starch cake in a starch plant. [5] There is an inverse correlation between gelatinization temperature and glycemic index. [4] High amylose starches require more energy to break up bonds to gelatinize into starch molecules.
In addition, sugars produced from processed starch are used in many processed foods. Mixing most starches in warm water produces a paste, such as wheatpaste, which can be used as a thickening, stiffening or gluing agent. The principal non-food, industrial use of starch is as an adhesive in the papermaking process.
Pentastarch is a subgroup of hydroxyethyl starch, with five hydroxyethyl groups out of each 11 hydroxyls, giving it approximately 50% hydroxyethylation. This compares with tetrastarch at 40% and hetastarch at 70% hydroxyethylation, respectively. It is sold under the name Pentaspan and used for fluid resuscitation.
Products made through extrusion cooking include many breakfast cereals and ready-to-eat snacks, confectionery, some baby foods, full-fat soy flour, textured vegetable protein, some beverages, and dry and semi-moist pet foods. Food products manufactured using extrusion usually have a high starch content.
A dish of staka served as part of a meze, Souda, Crete. Staka (στάκα) is a type of roux particular to Cretan cuisine. It is prepared by cooking sheep's milk cream over a low flame with wheat flour or starch: the protein-rich part of the butterfat coagulates with the flour or starch and forms the staka proper, which is served
