Last Saturday evening I was having  some ‘cheetos pelotazos’ at home,  when I found this ‘thing’ inside my snack bag, and I thought … what the heck is this? Is this another sticker for my daughter? …  But when I watched it, I could read: ‘Do not eat; Oxygen absorber’
It is curious how Food Technology Industry works on product safety.
By the way, these items are also called oxygen scavengers.

I´ll post listening exercise number 2 in a while, it is related to oxygen absorber.

Have fun,
