Hi, this depends how realistic you want it to look.
You can try and play around with some of the filters that photoshop has built in example frosted glass or plastic wrap and a combination of a few.
If you want far more realistic results then this project will require a "number" of workflow solutions, and experimentations as well as manual painting which of course will require a certain level of skill.
You could also select certain parts of the strawberry:
give it a bit of a feather, then add a light grey fill (new layer)
add noise and gausian blur
then clip an adjustment layer to adjust tone/value as desired
