Ascorbic acid (Vit C, or 'Fruit Fresh') question and oxidation reduction observation

I have done a lot of reading and thanks to hours worth of searching for all sorts of information over the past few months, i just harvested my first few fruits. very nice, thank you to all those whose questions and answers I found so helpful.
So now, a specific questions about ascorbic acid. Vitamin C is used to prevent oxidation of the good stuff. Fruit Fresh is a product that is composed of powdered Vit C along with lots of other stuff to help preserve, mostly lots of sugars. In all the searching and reading I have noticed that most of the people who use it tend to mix it in water then soak for a period of times. Basically, I did this for a short period of time, then the outside layers became nearly translucent. I then took them out of the water and sprinkled a layer of fruit fresh all over the mushroom and then placed it onto my dehydrator. This is how it is typically used with fruit anyway. So my question is more just curiosity for those who have used it before. Do you notice any reduction in bluing when using this product? do you soak or sprinkle? So if you use this stuff, or something similar, which way do you prefer to do it? what reasons do you have for soaking instead of sprinkling? it would seem to me that the outside is the only real area where oxidation can take place, so sprinkling it will give a much nicer cover to protect it. plus, the sugary good taste might make it easier to eat once dry. I know that this has been discussed before,sort of, but Ive been unable to find a reason people soak instead of sprinkle. Since youre going to be drying them anyway, why soak them, getting them even wetter

update: this morning they were all nearly dried, and not a single spot of blue on any of them. not even the base where i cut it off the cake with sissors. in contrast, the stumps of the mushrooms i cut off of the cake were heavily blued. using the fruit fresh sprinkled on actually caused the initial mushroom bluing that started as soon as i cut them off to disappear. So, sprinkling it on and giving it a coating works very well, plus i got them into the dehydrator much faster than letting them sit in a bowl of water with the stuff for a few hours. I am using a food dehydrator to dry btw.
anyone else care to try this when they dry next time who has not tried it before? since this is the first time ive grown anything, i dont have the experience of how much they normally blue when drying.

I've wondered myself and assumed this would work. Have gone so far as to add vitamin C to my substrate as an experiment to see. That would be totally awesome if somehow its absorbed and prevents psilosin from being oxidized, but I'm not so confident its going to make a difference... was just something to play with. Have a few vitamin C fed cakes showing primordia just now, will find out soon enough. Good stuff 
As for experience with blueing, sometimes they do a little, sometimes they do a lot, sometimes they don't at all. So its really hard to gauge if any of this is helping anything. Although, if you snipped with scissors and they were going to blue, they would have done so pretty obviously almost immediately, before you had a chance to coat them with the vit c...

thats right, the bluing actually went away. it started to get blue within a minute of cutting it and i had it in the vit C solution for about 15 mintues before i decided to just sprinkle some on top. so, yes it did 'fix' the discolouration, but it really only had maybe 5-10 minutes to start bluing anyway. this is why I posted this, because it seems like it could be very useful, but few people seem to know about/use it. I would be interested in waiting an hour or so to let the bluing set in then try it to see if the blue reversal still works.

another update: after sprinkling a nice coating onto the stumps of the mushrooms cut earlier, the heavy dark blue that was there cleared up. the mushrooms have taken a while to dry, over 24 hours in a dehydrator, and they still have a very tiny bit of moisture left in them. this is probably because the sugars and such are forming a barrier around them. it is leaving a light pink coat on them in spots. no bluing whatsoever tho. i will test them tomorrow and see if they taste good:)
