Definitions

  • the present invention relates to a lactic acid bacteria composition, a process for the production of a lactic acid bacteria composition using such an additive composition, a starter culture or kit of parts comprising such lactic acid bacteria composition, a process for making a food or feed product, preferably a fermented milk product, using such lactic acid bacteria composition, and the use of such lactic acid bacteria composition in a process for making a food or feed product.
  • Lactic Acid Bacteria are used world-wide in the dairy industry to produce a variety of fermented dairy products such as cheese, yoghurts, sour cream, kefir, butter and koumiss. Selected strains of lactic acid bacteria initiating and carrying out the desired fermentations are essential in the manufacture of the above products. They are often referred to as starter cultures.
  • LAB are in high demand for their health benefits. These are also referred to as probiotics.

  • the acidifying activity of the frozen, spray-dried or freeze-dried lactic acid bacteria compositions after shelf-life remains acceptable, does not decline or may even increase and/or if the stability, quality or overall appearance of the frozen, spray-dried or freeze-dried lactic acid bacteria compositions after shelf-life, remains acceptable, does not deteriorate or even improves.
