Lockjaw Posted February 17, 2013 Share Posted February 17, 2013 and what is air made of? Nitrogen, oxygen, carbon dioxide, water vapour and some inert gases. Why? Link to comment Share on other sites More sharing options...
Chris_Sleeps Posted February 17, 2013 Share Posted February 17, 2013 Sorry to spoil the party but unopened crisp packets don't contain air. To prevent microbes doing any work? Never considered that before but it makes sense. Another point; Pringles are not crisps. They contain under 50% potato and the rest is made up of rice flour.

Also, the crisps would go a bit soggy if there was air in the bags because they would absorb the water vapour. Link to comment Share on other sites More sharing options...

Also, the crisps would go a bit soggy if there was air in the bags because they would absorb the water vapour. Presumably more so if they were ready-salted? When crisp packets contained a packet of salt (not the sealed, rectangular ones but the blue paper twists), I wonder if that alleviated the soggy crisp problem to some extent. I do remember, in the days before inflated packets, that rancid crisps were a regular disappointment. Link to comment Share on other sites More sharing options...
aliceBB Posted February 17, 2013 Share Posted February 17, 2013 Is anyone else fed up of buying bags of air with 6 crisps in it? Because I for one am pee'd off! So stop buying packets of crisps. They are bad for you in all sorts of ways. Eat apples instead. Link to comment Share on other sites More sharing options...
