I know we are talking LL here, however, I would say the guidance would be the same.
OUT OF DATE STOCK
--------------------------------------------------------------------------------
I have had a discussion with the head of production and clarified the issue.
Official Guidance - what happens after best before date
Powders
The vitamins and minerals start to deteriorate.
The flavour changes and will start to taste stale.
The fats, essential fats are added, sunflower oil is added, and the soya flour contains fat these are the elements that become rancid.
Tetras
These become thick and all of the above apply.
Bars
Bars harden and as they have the fats added the rancid problem again arises along with the reduction in vitamins and minerals.
So advice from CD Head Office use the packs before the best before
