The Royal Flavor Black Sesame Paste comes with no preservatives. According to my information, Royal Flavor Black Sesame Paste is a natural food and does not come with preservatives. The process of making black sesame paste usually includes steps such as grinding black sesame seeds, heating and mixing, and there is no need to add preservatives. However, I would suggest that you check the ingredient list on the product packaging or consult the brand's official customer service to ensure that it is preservative-free.
