Allow food to be kept for 30 minutes (even across dead)

I know may sound stupid but there are some foods that REQUIRES time to be gathered and created, we can't lower the price so much because they do require time but... let's think about it: a food costs 6k, I can't imagine anyone using those (I'm speaking about combat foods), for example if someone disconnect for 1 minute right at the start of the battle, you have lost 6k gils in 3 seconds?
Isn't it a too big punishment? I think food must last 30 minutes, no matter what happens.
This maybe will result in even a better market share for culinarian, so an improvement for everyone

I didn't find the right solution from the Internet.
