I make my own Acorn scent every year with acorns from the area I hunt.

I have an old cast iron meat grinder. In the autum after the mast crop falls I gather up about 4 to 6 cups of acorns and grind them up shell and all. I place them in a gallon jug and pour in a liter of cheap Vodka. This sits until the next hunting season.
I drain off the liquid and place it in smaller bottles to carry in my pack pack and use it as an attractor scent. I've seen Deer stop, change direction and lick it off rocks and tree truck. No they don't get hammered, the Vodka evaporates. You can also dump the acorn pulp on the ground but make sure solid bait is legal in your are before doing so.

I have not tried it but Im sure that this would work with other food products such as apple, corn or what have you. The vodka is just a carrying agent that lets the acorn scent remain and concentrate without spoiling.

works for me
