Eternal Yogurt: The Starter That Lives Forever

Image
If you make your own yogurt, there's a chance your yogurt could outlive you.
That's because some bacteria that grow and feed on the sugar in milk – the process that ferments milk into yogurt — can procreate indefinitely in new generations of yogurt.

But not all yogurts have these immortal powers. The typical store-bought yogurt only carries a few strains of bacteria that have been isolated by scientists. Those bacteria on their own can't regenerate very long – maybe just a generation or two.

That's one reason yogurt enthusiasts are now rediscovering heirloom yogurt starters, many of which originated in countries like Finland and Bulgaria with long traditions of yogurt-making. These bacterial cultures, which live on in yogurt or in freeze-dried powders now sold by one company, are made up of diverse communities of bacteria that together can take over one batch of milk after another.

  1. There is no problem if the yoghurt starter culture outlive the discoverer.The important thing is that the desireable characteristics (such as flavour,colour ,taste) inherent in the starter culture is continuously maintained or possibly improved. This can possibly guarantee increased demand for the yoghurt.
