原文

Over the last few years, plant-based alternatives to meat and dairy have become increasingly widespread. However, for many, they simply don't come up to scratch in terms of flavour, texture or ease of use.

But now, a number of start-up companies, like MeliBio, are looking to use fermentation to produce vegan products that are identical biologically to the real thing.

Through the process of fermentation, micro-organisms digest a food supply and excrete a useful product - yeast, for example, is fed sugars and produces alcohol to make beer.
