The capability to produce lactic acid is one of the reasons why L. lactis is one of the most important microorganisms in the dairy industry. [5] Based on its history in food fermentation, L. lactis has generally recognized as safe (GRAS) status, [6] [7] with few case reports of it being an opportunistic pathogen. [8] [9] [10]
Special interest is placed on the study of L. lactis subsp. lactis and L. lactis subsp. cremoris, as they are the strains used as starter cultures in industrial dairy fermentations. [5] Their main purpose in dairy production is the rapid acidification of milk; this causes a drop in the pH of the fermented product, which prevents the growth of ...
After pasteurization, the mixture is cooled down to a temperature of 20˚C, an ideal temperature for mesophilic inoculation. It is then inoculated with 1–2% active starter culture. The starter culture initiates the fermentation process by enabling the homogenized cream to reach a pH of 4.5 to 4.8. Lactic acid bacteria (LAB) ferment lactose to ...

Using Lactobacillus as starter cultures for the dairy industry depends on the number of viable and active cells. Currently, the preferred method to preserve the bacterial cells is through freeze-drying, however this also results in some strains being killed.

Milk and dairy drinks with protein claims had less total and saturated fat, and yogurts and fermented milk products with protein claims had less carbohydrates and sugar. Next, researchers looked ...
The bacteria is included in dairy starter cultures since they are able to produce metabolites needed for dairy production. These metabolites include diacetyl and CO₂ from citric acid. Diacetyl is important for dairy because it is the main source of aroma and flavor in many different dairy products, like buttermilk, butter, and different ...
