Inside The Factory viewers all have the same question as Gregg Wallace reveals how Doritos are really made

INSIDE The Factory viewers have all had the same question after Gregg Wallace revealed how Doritos are really made.

Wednesday's episode of the BBC series saw Gregg and co-star Cherry Healey explore how the millions of tortilla chips are made each year to be devoured by the nation.

While Gregg went to the factory that makes Doritos, Cherry also explored how crisp packaging is transforming to be better for the environment.

Cherry explained how hard it is for crisp packets to be recycled due to the thin layers of plastic, before visiting a factory that was helping a different brand produce the first plastic-free crisp packet in the UK.

The process saw the factory workers turning sustainable wood pulp from South America into a film that looks like plastic but is biodegradable.

The segment featured lots of shots of the different elements of the process, but the presenters didn't name the crisp brand using the game-changing packaging directly.

It left viewers desperate to know where to find them, with one writing on Twitter: "Which brand is that using the compostable bags ? And why doesn’t everyone?";

Another added: "Handy to not show the brand of crisps using the paper bags."

A third tweeted: "BBC2 #insidethefactory Please could you tell us who makes the biodegradable crisp packets from your programme tonight? #savetheplanet."

Meanwhile another shared: "Would be good to know which company uses the biodegradable crisp packets so we can switch to them #InsideTheFactory."
