About
Tara gum is a purified galactomannan polysaccharide extracted from the endosperm of seeds of the South American tara tree (Caesalpinia spinosa), appearing as a white-to-yellowish powder. It is used in food as a thickener, stabiliser, emulsifier, and gelling agent in dairy products, frozen desserts, sauces, bakery goods, and meat products.
Safety summary
EFSA and JECFA both assigned an ADI of 'not specified', indicating low toxicity; no adverse effects were found at the highest tested doses in subchronic, chronic, and carcinogenicity studies, and no genotoxicity concern was identified. Tara gum is unlikely to be absorbed intact and is expected to be fermented by the intestinal microbiota. Consumers should be aware that tara flour (a distinct whole-seed product from the same plant) was associated with a 2022 hepatotoxicity outbreak due to the non-protein amino acid baikiain — this hazard is not attributed to the purified E417 gum additive.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| FSANZ (Food Standards Australia New Zealand) (Australia) | Approved | Approved under Schedule 2 (Miscellaneous additives permitted in accordance with GMP in processed foods) of Standard 1.3.1 – Food Additives. FSANZ Final Assessment concluded no public health and safety concerns.source |
| Health Canada (Canada) | Approved | Health Canada approved tara gum as an emulsifying, gelling, stabilising, and thickening agent in unstandardised foods and certain standardised foods, including bread, following pre-market safety and efficacy assessment.source |
| EFSA (European Food Safety Authority) (European Union) | Approved | Authorised as a Group I food additive under Annex II and III of Regulation (EC) No 1333/2008 across 67 food categories. EFSA re-evaluation (2017) confirmed ADI 'not specified' — no numerical ADI required. Use governed by Good Manufacturing Practice (GMP) limits.source |
| MHLW (Ministry of Health, Labour and Welfare) (Japan) | Approved | Tara gum is listed as a permitted food additive in Japan, as noted in FSANZ assessment documentation.source |
