why drink immediately?

My partner just suggested I take a ready made up flask into work, I said I couldn't cause they need drinking straight away, he asked why, i said 'dunno - something to do with the vitamins or something' and he laughed and said that unless these packs contain some kind of malicious enzyme, then the vitamins wont be affected..

So... does anyone know why?

"I think" its because the nutrition value of the vitamins starts to decrease after 15mins, so you wont be getting the correct amount of vitamins etc....


Gone fishing
The main reason is because of a change in texture, though Cambridge also say there could be a very small amount of vitamins and minerals degrade too.
