If you see any pulp in your oat beverage, it is highly likely to be part of the oat When producing the drink, it is subjected to mechanical processes (centrifugation) to remove most of the insoluble fiber but not all, to prevent the beverage from being watery and without body. Since the product has no additives, emulsifiers, or gums that allow the fiber to be kept in suspension, some amount of fiber is deposited at the bottom of the container. Typically, the fiber that remains in the drink should remain in suspension and not accumulate at the bottom, but sometimes it does. Sometimes shaking the carton can help redistribute the pulp. In no case is it dangerous to consume it since it is the fiber of the oats itself, although we understand that it can be unpleasant to find.
