Glucono delta-lactone (GDL) is a product sourced from plant-based raw materials, found naturally in honey and grapes, for example. After the dehydration of gluconic acid (elimination of a water molecule), we obtain glucono delta-lactone. Roquette expertise guarantees a very pure crystallised GDL (several particle sizes available)., P3 [4 A9 @$ h. x; B
Highly soluble in water, GDL is progressively hydrolysed into gluconic acid, resulting in a regular fall in the pH. It can thus be considered a progressive acidifying agent.0 H7 O' l& b( z [# k2 j/ s
The acidifying character of GDL gives it interesting functionalities as a raising agent; GDL also helps to reduce salt content and even improve the conservation of foodstuffs. The neutral flavour of GDL is also a property looked for in this product.5 r t2 c4 k+ w+ v' D" K9 I
GDL is one of the many functional solutions that the Group offers to the food processing industry and, more specifically, in the cheese making, bakery and culinary products sectors. 4 M! J.
