Wicked1, morning.... Bride had a food service license for serving at Costo to the public.... Any fruits had to be dipped in a very mild chlorine bleach solution for 10 minutes and then rinsed and stacked to drip/air dry.... Might be a consideration not knowing who or how the fruits were handled.... After reading on disinfecting dips, fruits, vegetables etc., there are many variations on the concentration depending on the variety... Not saying it is necessary, but a good practice... If wiping after dipping, a paper towel dipped in the bleach, is recommended if not left to air dry....
Who knows what the store clerk has on his/her hands while stacking the fruits...
Back to drying apples.... We have a "Sausage Maker" D-10 fan forced dryer.... we dry every kind of food.... One thing I found that has saved a ton of work is using parchment paper on the shelves... the food grade silicone in the paper stops stuff from sticking.... no clean up...
All the suggestions from the others is right on.... Good drying....
Food for thought.... Dave
