Which natural preservatives have been used to increase the shelf life of cranberries?

Our cranberries are renowned for their exceptional purity. They are free of any preservative, artificial flavours or colours & added sugar. The cranberries are infused with pure apple juice, enhancing their flavor while maintaining their natural integrity. To ensure their freshness, we use only a minimal amount of sunflower oil, less than 0.5%, in our process. This gentle coating helps preserve the cranberries without compromising their quality. When you choose our cranberries, you can savor the true essence of this remarkable fruit in its purest form.
