I don’t really examine any food, i am more apart of the production of food from a grass/agricultural angle. But I would imagine yoghurt or cheese would be interesting because of all the bacteria in them
I love working with dairy. It is so diverse and can transform into so many different products from drinking milk, cream, powder, cheese and yoghurt all with their own individual properties, processing pipelines and different microbes found in them.
