Description | Diglycerides (DGs) are also known as diacylglycerols or diacylglycerides, meaning that they are glycerides consisting of two fatty acid chains covalently bonded to a glycerol molecule through ester linkages. DG(8:0/8:0/0:0), in particular, consists of one chain of caprylic acid at the C-1 position and one chain of caprylic acid at the C-2 position. Mono- and diacylglycerols are common food additives used to blend together certain ingredients, such as oil and water, which would not otherwise blend well. Diacylglycerols are often found in bakery products, beverages, ice cream, chewing gum, shortening, whipped toppings, margarine, and confections. |
