Cheese and yoghurt are products of
Fermentation
The chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the release of heat, is called as fermentation. It is through the process of fermentation that commercial products like yoghurt and cheese are processed, involving the action of specific bacteria like LAB (lactic acid bacteria) for the manufacture of yoghurt, and some fungi in the production of different types of cheeses. For example, Blue cheese is produced by Penicillium roqueforti and Penicillium glaucum molds. Distillation is a process of separating the component or substances from a liquid mixture, by selective evaporation and condensation. This distillation process is generally employed for the production of beverages in brewery industries. Pasteurisation is a process of sterilisation through heat treatment or irradiation of products like milk, curd, wine etc. before consumption by the consumers.
