What is GDL (Glucono-delta-lactone, E575)

An important function of fermenting sausages is lowering the pH. It is also the most risky, difficult part. Couldn’t you just lower the pH with vinegar, lemon juice or the battery acid? Yes, that’s possible. Many sausage makers do it this way. Not with battery acid, of course. They use Glucono-delta-lactone, or GDL, a naturally occurring food ingredient. It is used in the production of food products to lower the pH, or increase the acidity, of a product. In addition to an acidity regulator, you can also use Glucono-delta-lactone to slow the deterioration of your product and prevent discoloration.

It is guaranteed to work, 100% safe and you do not have to ferment anymore, it just works while your sausage is in the fridge.


  • 100 grams of GDL
  • GDL is also known as E575


GDL lowers the pH by about 0.1 point per gram per kilo. Assuming a fresh pork pH of 5.5-5.8, you need 6 grams per kilo to lower from 5.8 to 5.2, or a maximum of 12 grams to ferment to a slightly safer pH of 4.6.

How do you use GDL

  1. Add the GDL- with nitrite salt and seasoning-  to your sausage meat
  2. Make your sausages
  3. Leave the sausages in the fridge for two days to acidify
  4. Move them to your drying room.
  5. Then dry the sausages after the two days in the refrigerator for about 4 to 5 days at room temperature.

Optionally, you can combine this method with a slow starter, for example a RAPS biostart plus or a Primal SK soft, which gives virtually no acidification but lots of flavor.
