Yoghurt Yoghurt is made by introducing specific bacteria strains into milk, which is subsequently fermented under controlled temperatures and environmental conditions (inside a bioreactor), especially in industrial production. The bacteria ingest natural milk sugars and release lactic acid as a waste product. The increased acidity causes milk proteins to tangle into a solid mass (curd) in a process called denaturation. The increased acidity (pH=4-5) also prevents the proliferation of potentially pathogenic bacteria. These include L. acidophilus, L. casei and Bifidobacterium species. In most countries, a product may be called yoghurt only if live bacteria are present in the final product. Non-pasteurised yoghurt can be marketed as "live" or containing "live active culture". A small amount of live yoghurt can be used to inoculate a new batch of yoghurt, as the bacteria reproduce and multiply during fermentation. Pasteurised products, which have no living bacteria, are called fermented milk (drink). We are told that live cultured yogurt can be made only if the milk is fresh from the animal, giving the maker the opportunity to introduce the desired cultures before the normal "unfriendly" bacteria will go to work. Yoghurt has nutritional benefits beyond those of milk: people who are moderately lactose-intolerant can enjoy yoghurt without ill effects, because the lactose in the milk precursor is converted to lactic acid by the bacterial culture. The reduction of lactose bypasses the affected individuals' need to proces the milk sugar themselves.Yoghurt also has medical uses, in particular for a variety of gastrointestinal conditions and in preventing antibiotic-associated diarrhea. Well so much for all the technical stuff. If you love yoghurt, there can be no better fun than to try this yourself.
