Hi Olga
Thank you for contacting us.

You can add preservatives and gums to the recipe but that would change the eating quality. Keep in mind that certain coatings, icings and toppings may also deteriorate the shelf life (ex: powdered sugar dissolves and decreases your shelf life).

I suggest you take your donuts to the next level and expand to sell into all day parts. An example would be to offer rings filled with whipped topping and/or a creamy, savory filling. Packaging may also be something to think about.

We offer an extended shelf life yeast donut mix. Please contact your local CSM representative and ask for a sample.
