If you have asthma, or are susceptible to getting "red wine headaches",
stop reading and close this message now. Otherwise, page down.





















To keep apple slices from turning brown, dissolve 1/4 tsp Super Iron Out
rust stain remover (the same white crystals you use to clean the rust
out of your water softener once or twice per year) in a quart of water,
and dip the apple slices in the solution as you peel them. They will
then stay white and fresh looking for days in the refrigerator. It's
also good if your going to dehydrate the apples. Be sure and label the
package "Treated with Sulfites", although that should be obvious from
their white color.

You can also use 1/2 of a Campden tablet (available from winemaking
supply stores) dissolved in a quart of water to accomplish the same thing.

Best regards,
Bob

I wouldn't do that, even if the chemical compound is the same. The
purity is probably NOT the same as the food-grade compound would be,
and it is probably carrying with it things such as heavy metals. You
can buy Fruit Fresh at the grocery store which is citric acid (food
grade) and accomplish the same thing, and ensure your safety as well.

I'm with you on that one, Lyn. Fruit Fresh has always worked well for me.

I use a little bit of dissolved Ascorbic Acid crystals.
They are cheaper. :-)

Lemon Juice works well too.

I'd certainly never use a cleaning product!

Ew!

The chemical is not the same. This is sodium bisulfite, not ascorbic
acid. I think it *is* food grade because the label says it can be used
on dishes and cookware (including plastic), and in water softeners.

I prefer using Campden tablets because they are designed for treating
grape juice so I *know* they are food grade. I think the Super Iron Out
is food grade also, from what is implied by the label. (maybe I need to
call the company and find out.) And did you notice the dilution rate?

Best regards,
Bob

I have asthma, should I not be drinking wine right now?

I doubt Iron Out is food grade, and you'd need to determine the correct
concentration for food use... I wouldn't recommend playing food chemist
without proper credentials. Acidulated water via fresh lemons works
fine and is perfectly safe.

probably cheaper too. Out of one lemon you can get zest, juice and then
toss the rest in the disposal to make it smell good.
