I'd say no. The carboy design keeps the surface area which is succeptible to oxidizing to a minimum. The food grade container I'm picturing you're speaking of is like a primary. Lots of surface area that the oxygen could mess with.
thanks again all.
guess i will go back to store and buy some more carboys
i was buying them for 19.90 for 5gals
but they raised the price to 26.95 they said it was because of shiping
but they had them for years. so i quit buying. Guess i will eat my hat.
