Xanthan gum
Xanthan gum is a high-molecular-weight polysaccharide made by fermentation with nonpathogenic Xanthomonas campestris and then purified. In food, it helps thicken liquids, keep ingredients evenly suspended, improve body or mouthfeel, stabilize emulsions, and improve texture in sauces, dressings, beverages, dairy products, gluten-free baked goods, and other formulated foods.

What this is
Xanthan gum is widely permitted as a food additive under ordinary good-manufacturing-practice or category-specific limits. U.S., Codex, Canadian, EU, EFSA, and JECFA sources generally treat it as a low-to-limited concern hydrocolloid when it meets food-grade specifications. EFSA concluded in 2017 that a numerical ADI was not needed for the general population, and JECFA lists the ADI as not specified. The main caution is narrow: historical reports linked a xanthan-gum-containing thickener product to NEC cases in premature infants, with causality uncertain. Later JECFA and EFSA infant-formula reviews found no safety concern for reviewed maximum levels and uses. Recent EU action updates use conditions and specifications for xanthan gum and related hydrocolloids, especially in infant/young-child contexts, but does not amount to a broad ban.
Safety Review
The health areas reviewed when evaluating an ingredient. This does not mean the ingredient is proven to cause harm.
EFSA/JECFA did not identify genotoxicity, carcinogenicity, reproductive, or developmental toxicity concerns for reviewed uses. The practical note is GI and vulnerable-population focused: some adults reported abdominal discomfort at high short-term intake, human gut bacteria can degrade xanthan gum, and historical FDA/CDC/case-report evidence linked xanthan-gum-containing thickeners to necrotizing enterocolitis reports in premature infants.
