Chocolate spread preservation

I have tried and made chocolate spread at home. I made it using a melted milk chocolate slab added to boiled Amul fresh cream. After a few days, it grew some fungus. How can its life be increased? What should be added to act as a preservative and in what ratio? It was kept in a plastic container under normal room temperature as I want to sell it in market. Also, what precautions can be taken before sealing the containers? What is the minimum life expected in a sealed plastic container under room temperature? 1litr boiled fresh cream mixed with 1.2 kg of melted chocolate slab.
Best Answer
Use sterilised glass jar/s similar to jam making and pickling, you can place some plastic wrap (cling film) over the top of the jar before sealing as an additional air/moisture barrier. Also think of possibly dividing into smaller portions.

How do you preserve chocolate spreads?
Store it in a jar or other container with a tight fitting lid. I like to use canning jars because they look pretty and have reusable lids. If you refrigerate chocolate hazelnut paste, let it soften at room temperature before using. For very long-term storage homemade Nutella can be frozen.How long does chocolate spread keep?

Try to keep a habit of leaving the containers of your spreads open for only as long as you need to use them, and then seal their lids so no air can get in. While your unopened spreads can last a good while in the pantry, refrigerating them will help them go the extra mile after opening them.Does chocolate spread need to be refrigerated?
Nutella\xae should be stored at room temperature (between 64\xb0 and 72\xb0 F). Keep the container tightly closed and store in a cool, dry place to maintain maximum flavor. Do not refrigerate Nutella\xae, otherwise it will harden and become difficult to spread.Chocolate spread production
