How does acidofilní mléko differ from other types of milk?

Quick answer

Acidophilus milk (acidofilni mleko) is cow's milk with live Lactobacillus acidophilus bacteria added. The sweet type tastes like regular milk; the fermented type is tangy, like kefir or yogurt. It still contains lactose, unlike lactose-free milk, and it is not suitable for a cow's milk allergy.

What is acidophilus milk?

Acidophilus milk is cow’s milk with live cultures of Lactobacillus acidophilus, a probiotic bacterium. It is sold as a probiotic milk. It is still dairy milk, so it provides the same basic nutrition as milk of the same fat level.

How does acidophilus milk differ from regular milk?

Milk What is different
Regular milk Contains lactose; no added cultures
Sweet acidophilus milk Live cultures added; taste is close to regular milk
Fermented acidophilus milk Cultured so it is tangy and thicker, like kefir or yogurt
Lactose-free milk Lactase added so the lactose is already broken down
Plant milks Not dairy; different nutrition

What is the difference between sweet and fermented?

The sweet kind tastes very similar to regular milk, while the fermented kind has a tangy taste from the probiotics. Sweet acidophilus milk can be swapped 1:1 for regular milk in recipes. Check the label to see which you have.

Is it the same as lactose-free milk?

No. Acidophilus milk keeps its lactose and relies on the bacteria to help with digestion, while lactose-free milk has the lactose broken down with added lactase. The two are different products, so choose lactose-free if you react strongly to lactose.

Who is it for?

  • People who want a probiotic-containing dairy product.
  • Not for people with a cow’s milk allergy, nor for vegans.

How long does it keep?

One source says both types typically last around 7 to 14 days in the refrigerator, but check the date on the pack and the smell. Keep it cold and do not leave it out.
