Earlier in July, 2025, Tianjin Hesheng’s 2'-FL was also successfully authorized as a new food additive in China, with the support of CIRS Group. Remarkably, it took only about seven months to complete both the FDA GRAS notice and China's new food additive registration, from submission to final approval.
The obtaining of these two certifications not only demonstrates the high quality and exceptional R&D capabilities of HS SynBio, but also showcases CIRS’s professional expertise in global new ingredient regulatory compliance.
