Starter Culture Preparation

Commercial manufacturers provide starter cultures in lyophilized (freeze-dryed), frozen or spray-dried forms. The dairy product manufacturers need to inoculate the culture into milk or other suitable substrate. There are a number of steps necessary for the propagation of starter culture ready for production:

  1. Commercial culture
  2. Mother culture - first inoculation; all cultures will originate from this preparation
  3. Intermediate culture - in preparation of larger volumes of prepared starter
  4. Bulk starter culture - this stage is used in dairy product production
