Proper dehydration is the key to preserving tutti frutti for a longer time. Also, these are sugar dunked, and we all know that sugar is a natural preservative. Homemade tutti frutti keeps well for months if it is made and stored properly. We have to understand that there should be no excess moisture left in the prepared tutti frutti.    Also, choose a dry and clean airtight container to store the tutti frutti. The last batch I made, was 3 months ago and I finished it last week only. I noticed no discoloration or false odor issue in the past 3 months.  I stored it in my refrigerator.
