13 May 2020 --- Food manufacturers can now use “natural dietary fiber” as a claim on products featuring Taiyo’s Sunfiber dietary fiber. The ingredient has been classified as 100 percent natural by the International Organization for Standardization (ISO) – technical specification, ISO 19657:2017. As a result, manufacturers can also simplify the certification process for their own products. Natural guar bean fiber is one of the rare, truly pure plant-based fibers that allows formulators to enrich and enhance high-quality foods, according to Taiyo.
