The FDA has ruled in favor of a citizen petition requesting dietary fiber status for MGP Ingredients' Fibersym RW and FiberRiteRW -- both resistant starches 4 (RS4) -- with the agency stating that it will propose that cross-linked phosphorylated RS4, regardless of source, be added to its definition of fiber.

Last year, the FDA provided guidance​ on which isolated or synthetic non-digestible carbohydrates it believes should be classified as 'dietary fiber' that at the time did not include RS4.

"The action was taken in response to a citizen petition from MGP Ingredients Inc. Dietary fiber that can be declared on the Nutrition and Supplement Facts labels includes certain naturally occurring fibers that are "intrinsic and intact" in plants and added isolated or synthetic non-digestible soluble and insoluble carbohydrates that FDA has determined have beneficial physiological effects to human health," ​the agency said in a statement ​issued yesterday. 

"Based on available evidence, FDA has determined that the scientific evidence suggests that cross-linked phosphorylated RS4 can help reduce insulin levels following a meal containing a carbohydrate that raises blood glucose levels."​ 

Until the FDA completes rulemaking regarding adding additional fibers (i.e. RS4) to the regulatory definition of dietary fiber, the agency intends to exercise enforcement discretion to allow manufacturers to include the amount of these additional fibers in the dietary fiber declaration on the Nutrition and Supplement Facts labels.

Therefore, Fibersym and FiberRite can continue to provide dietary fiber benefits on food labels to support the growing opportunities for healthy food applications, MGP Ingredients said.

"These two fiber ingredients continue to be the smart choice for food product designers and formulators who are looking to boost fiber and lower calories of many food products while delivering health benefits to the consumers,”​ said Ody Maningat, Ph.D., vice president of MGP Ingredients R&D and chief science officer.

Fibersym RW​ is a resistant wheat starch which delivers a minimumTotal Dietary Fiber of 90% (dry basis), and performs well in a variety of foods, particularly flour-based items. 

FiberRite RW​ is a resistant starch performs as a partial fat replacer and lowers caloric content, while also adding dietary fiber to food such as as yogurt, salad dressings, sandwich spreads, sweet goods, sauces, confections, and frozen desserts.
