SoPure™ Stevia Receives 2nd FDA “No Questions” Letter for GRAS Notice of New Stevia Sweetener

GRAS Notification for SoPure™ Stevia Enzyme-Modified Steviol Glycosides

February 23, 2022 — HOWTIAN®, formerly known as Zhucheng Haotian Pharma Co., Ltd (ZCHT), has announced the reception of their 2nd FDA No Questions GRAS notice for another stevia sweetener product. GRAS Associates, a fully owned subsidiary of Nutrasource, successfully submitted the notice to the FDA on behalf of HOWTIAN, the world’s largest manufacturer of natural stevia extracts.

“We are excited to receive the Letter of No Objection from the FDA to our Enzyme Modified Steviol Glycosides (EMSG) GRAS notification. The response underscores the safety of HOWTIAN’s EMSG products, opening the opportunity to use them in a wide range of applications,” said Mavis Ran, Business Director at HOWTIAN. “HOWTIAN’s leaf-based product portfolio, which also includes our natural stevia extracts, minor glycosides, and specialized blends, offers more possibilities now to address the increasing consumer demand for low sugar or zero sugar food and beverage products using non-artificial sweeteners.”

Glycosoylated stevia products offer improved taste via enzyme-treated steviol glycosides that are extracted from the leaf. These can serve as sweeteners or flavor enhancers, mask unpleasant flavors and augment overall taste.

Amy Mozingo, Vice President of US Nutra Regulatory Sciences, Nutrasource/GRAS Associates shared, “GRAS Associates is pleased to have assisted adding another steviol glycoside preparation into the HOWTIAN portfolio permitted for import and use in the US marketplace with the successful GRAS conclusion and notification to FDA for their enzyme-modified steviol glycosides (GRN 999).”
