Cream of Tartar: How Much Vitamin K?

If you were concerned, don’t be.  Potassium bitartrate (AKA cream of tartar) has no vitamin K.  2 – 100 grams, no vitamin K.

How is it made?   According to Wikipedia (defaced it myself):

Potassium bitartrate crystallizes in wine casks during the fermentation of grapejuice, and can precipitate out of wine in bottles.

In food, potassium bitartrate is used for:

  • Stabilizing egg whites, increasing their heat tolerance and volume
  • Stabilizing whipped cream, maintaining its texture and volume
  • Anti-caking and thickening
  • Preventing sugar syrups from crystallizing
  • Reducing discoloration of boiled vegetables

Additionally it is used as a component of:

  • Baking powder, as an acid ingredient to activate baking soda
  • Sodium-free salt substitutes, in combination with potassium chloride
