Hey. So I am making a cake that will be used for display in a restaurant, so I will covering styrofoam with fondant. But do I need to preserve the fondant in any way, such as spraying it with something, in order to keep it from going bad or turning colors or getting mold or anything else that may happen??? thanks!
No, just keep it out of direct light (both sun & artificial), heat, or humidity.
It will last a long time, but nothing lasts forever. It will, eventually crack or fade, but if you do as directed above, that could take a year.
I made a fondant covered wedding cake as a display for a Wedding Show. I then brought it back and placed it in my shop as a display. I had not sprayed it with any type of preserver. After a couple of months, I noticed that ants had discovered the cake. That was the end of the display!
Just spritz it with ant spray. seriously.
No, seriously, I would not spray it with ant spray. My point is that fondant is a sugar based material that will attract little critters.
As has been mentioned nothing is needed unless you have a problem w/ants. Usually after a few months (up to a yr) you will want to change the style. If it is being displayed in a resturant it might get touched a lot &/or pick up discoloration from all the cooking so don't get too upset if it only lasts a few months.
ASpray the Fondant with clear varnish. They have a dull sheen so it won't make it shiny. But the varnish will seal in the smell and prevent it from cracking. It will still fade.
AMy dummy cakes are in a case never touched by customers. I DO spray them with ant spray when needed. It poses no problem.
AI just recently had a florist tell me that she has a display cake ...dummy cake....that is covered with fondant that is a few years old that she just sprayed it with spray paint. She is supposed to bring it by today, she wants me to make the flowers for it...I guess we'll see how it looks!
