The Color Additives from Natural Sources Working Group is a newly established working group, composed of four contaminant-specific subgroups, to develop and adopt voluntary consensus standards for color additives from natural sources. Stakeholder-approved standards will be used in the development of Official Methods of Analysis for (1) microbial contaminants, (2) residual solvents, (3) pesticide residues, and (4) heavy metal contaminants in naturally derived color additives. Each sub-group will develop and adopt one or more Standard Method Performance Requirements, SMPRs® based on priorities established by the project’s Advisory Panel.

Current US regulation only requires synthetic color additives to be tested by the FDA and undergo the FDA certification process, prompting consumer demand for initiatives in natural color additives.
