Ascorbic Acid Preservative

Toast

Hello All - 

How much ascorbic acid do I need to add to my bread to get preservative benefits? I make big batches using 62lbs of flour at 61% hydration.

Thanks! 

...a preservative in bread, just in fruit and veg where it stops browning or colour loss (if that can be called a preservative). It's prime use in baking is to slow the effect of glutathione on yeast, allowing a open crumb to develop in wholemeal loaves. But it's not an essential ingredient at all.

"It's prime use in baking is to slow the effect of glutathione on yeast, allowing a open crumb to develop in wholemeal loaves." That's pretty darn questionable, far far off base, i'd say. 

There are several informative replies to this on the posters previous similar post.
