Hydroxyethyl starch. 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. [2][3]
Modified starch. Pack of modified food starch, a food additive which is prepared by treating starch or starch granules. Modified starch, also called starch derivatives, is prepared by physically, enzymatically, or chemically treating native starch to change its properties. [1] Modified starches are used in practically all starch applications ...
Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. [4]
The Summary. New research offers insight into the evolutionary history of amylase genes, which are key to our ability to eat and digest starchy food. A study found that human ancestors started ...
Starch is a common biodegradable additive, and blends of synthetic plastics with starch are becoming more and more prevalent. Because starch is a polymeric carbohydrate, it can be directly consumed by microorganisms. Starch is a renewable and cheap resource that is available all year round, making it a viable biodegradable additive. [1]
Chemical reaction between ethylene oxide and substrate. In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C2H4O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R (OC2H4)nOH ...
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Acetylated starch, E1420 in the E number scheme of food additives, is a modified starch. These are not absorbed intact by the gut, but are significantly hydrolysed by intestinal enzymes and then fermented by intestinal microbiota.
Acetylated distarch adipate (E 1422) is a food additive of the thickening agent type, and more specifically a bulking agent. It is also used as a stabilizer. This is an additive belonging to the family of modified starches. This is a starch that is treated with acetic anhydride and adipic acid anhydride to resist high temperatures.
