Overview

Şalgam juice is a traditional fermented beverage produced from black carrots and turnips and widely consumed in southern Turkey. It is characterised by a deep purple colour and a sour, salty flavour resulting from lactic acid fermentation.

Raw Materials

  • Black carrots (Daucus carota)
  • Turnips (Brassica rapa)
  • Bulgur flour
  • Salt
  • Water

Fermentation Process

The production of şalgam juice involves a two-stage fermentation process. First, bulgur flour, salt, and water are fermented to create a starter culture known as “şalgam dough.” This starter is then mixed with chopped black carrots and turnips and allowed to ferment for 5–10 days at ambient temperature, resulting in acidification and development of characteristic flavour.

Microbial Ecology

Fermentation is dominated by:

  • Lactobacillus spp.
  • Leuconostoc spp.

These lactic acid bacteria produce organic acids that contribute to the sour taste and preservation of the beverage.

Functional and Nutritional Aspects

  • Production of organic acids
  • Retention of vegetable-derived pigments and antioxidants
  • Mild preservation through acidification

Cultural Significance

Şalgam juice is widely consumed in Turkey, particularly in the Adana region, where it is traditionally served as a refreshing beverage and often accompanies grilled meat dishes.
