Dextrin

Dextrin is a type of carbohydrate that is produced through the hydrolysis of starch[1][3]. It is a water-soluble polysaccharide formed by the breakdown of starch, which is a complex carbohydrate found in foods such as potatoes, wheat, and rice[1][3]. Dextrin is made up of shorter chains of glucose molecules compared to starch and is classified into different types, including white, yellow, and British gum[3].

The chemical formula for dextrin is (C6H10O5)n, where 'n' represents the number of glucose molecules in the chain[1]. Dextrin is used in various applications, including as a thickening agent, adhesive, and stabilizer in foods, pharmaceuticals, and other industries[1][3]. It is also used as a fiber supplement due to its high soluble fiber content[1][4].

Dextrin can be produced from various starch sources, such as corn, wheat, or potatoes, and its production involves the use of heat, acids, or enzymes to break down the starch molecules[1][3]. The resulting dextrin can be used in a wide range of products, including tea concentrates, corn syrups, gravies, jellies, puddings, beer, hard candies, and frozen dairy products, among others[1].

In the context of food, dextrin plays a significant role in the browning process during cooking, particularly in carbohydrate-rich foods like bread and potatoes[1]. It is also used to enhance the crispness of food, such as in fried foods, and as a coating to improve texture[4].

In terms of gluten-free status, dextrin is often made from gluten-free ingredients like corn or tapioca in the United States, making it gluten-free[5]. However, dextrin made from wheat may contain gluten, and individuals with gluten-related disorders should exercise caution when consuming products containing dextrin[5].
