Worth knowing

Agar (E406) is a vegan alternative to gelatine, extracted from red seaweed, and has been used in Asian desserts for centuries. It sets at room temperature and won't melt on a hot day.

Conclusion

Konjac is a limited concern that mainly matters due to its specific restriction in jelly sweets, where its strong gel poses a choking hazard. Outside of those restricted confectionery uses, this natural plant gum acts as soluble dietary fibre and is confirmed safe by EFSA. Unless found in choked-risk jelly sweets, konjac is safe in standard foods.
