$ h, t- {! \0 B& ~/ hGlucono 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). " i1 E. f# z! m6 xHighly 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. # M$ `' {3 i+ H* L4 j; [ g! A" N+ EThe 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.3 W: u+ K6 j) X! m2 U9 ]
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.0 l1 y# |/ }3 E1 E* z! ]/ S3 ?
