What are dairy cultured products and how are they made?
Central to the production of cultured milk is the initial fermentation process, which involves the partial conversion of lactose (milk sugar) to lactic acid. Lactose conversion is accomplished by lactic-acid–producing Streptococcus and Lactobacillus bacteria.
How were cultured dairy products discovered?
Various cultured dairy products are formed by the conversion of lactose in milk to lactic acid by the use of starter cultures. Louis Pasteur declared that lactic acid could be formed from sugar fermentation by yeast (probably actually lactic acid bacteria) in 1857, as described and referenced by Manchester (2007).
Is cultured milk fermented?
When cultured milk is cultured, it often has already been pasteurized. Then, it is fermented and has a lactic acid bacteria culture added. Culturing was initially done because the process resulted in milk that stayed good for much longer before the advent of refrigerators.
Is milk a cultured dairy product?
Put simply, cultured dairy is a milk product that has been fermented with lactic acid bacteria.
What does cultured mean in yogurt?
Yogurt is a cultured or fermented milk product that is soured and thickened by adding specific lactic acid-producing cultures to milk. The basic cultures or probiotics used to make yogurt are Lactobacillus bulgaricus and Streptococcus thermophilus. Additional probiotics are often added.
What do cultured dairy products taste like?
Kefir is cultured milk that has been fermented with yeast and bacteria. The taste of the drink can vary depending on what type you buy, but it typically tastes tangy, sour, and a bit sweet. Sometimes the drink can be likened to cottage cheese, but other times, it may have a more acidic taste like pickles or yogurt.
Is yogurt a cultured dairy product?

What kind of taste does cultured dairy products have?
Basically, all yogurt is cultured milk. The bacteria used most commonly are Lactobacillus bulgaricus (named so because yogurt was first discovered by Europeans among the people of Bulgaria) and Strepto- coccus thermophilus. This is what gives yogurt its gel- like consistency and semisour, tangy taste.
What is raw or cultured dairy?
Fermented milk products or fermented dairy products, also known as cultured dairy foods, cultured dairy products, or cultured milk products, are dairy foods that have been fermented with lactic acid bacteria such as Lactobacillus, Lactococcus, and Leuconostoc.
Are there different types of cultured milk products?
A range of different Lactobacilli strains has been grown in laboratories allowing for many cultured milk products with different flavors and characteristics. Many different types of cultured milk products can be found around the world including milk, cheese, yogurt, other cultured dairy foods, ice cream and more.
When did they start making cultured dairy products?
With the development of microbiological and nutritional sciences in the late 19th century came the technology necessary to produce cultured dairy products on an industrial or commercial basis.
What kind of bacteria is in cultured milk?
What is the fermentation process for cultured milk?
Central to the production of cultured milk is the initial fermentation process, which involves the partial conversion of lactose (milk sugar) to lactic acid.
