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.
High amylose starches require more energy to break up bonds to gelatinize into starch molecules. Gelatinization improves the availability of starch for amylase hydrolysis. So gelatinization of starch is used constantly in cooking to make the starch digestible or to thicken/bind water in roux, sauce, or soup.
Modified starch may also be a cold-water-soluble, pregelatinized or instant starch which thickens and gels without heat, or a cook-up starch which must be cooked like regular starch. Drying methods to make starches cold-water-soluble are extrusion , drum drying , spray drying or dextrinization .
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.
In cooking, a leavening agent (/ ˈ l ɛ v ən ɪ ŋ /) or raising agent, also called a leaven (/ ˈ l ɛ v ən /) or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens the mixture.
However, a meta-analysis of trials that excluded Boldt's fabricated data found that the intravenous use of hydroxyethyl starch is associated with a significant increased risk of death and acute kidney injury compared with other resuscitation solutions. [4]
Modified starch is also used as textile printing thickener. In oil exploration, starch is used to adjust the viscosity of drilling fluid, which is used to lubricate the drill head and suspend the grinding residue in petroleum extraction. Starch is also used to make some packing peanuts, and some drop ceiling tiles.
Resistant starch content of cooked rice was found to decrease due to grinding; resistant starch content of oats dropped from 16 to 3% during cooking. [20] Other types of processing increase resistant starch content. If cooking includes excess water, the starch is gelatinized and becomes more digestible.
