Calcium bisulphite
Function: Preservatives
E227 is the European food-additive number for Calcium bisulphite, a preservative — used to extend shelf life by slowing spoilage from microbes. Calcium bisulphite (E227) is a food additive used as a food additive.
What is E227 used for?
Calcium bisulphite (E227) is a preservative — used to extend shelf life by slowing spoilage from microbes. It is added during food production for a technological purpose rather than for nutrition. See all Preservatives (E-numbers).
Is E227 safe or restricted?
E227 faces restrictions under EU rules on how, where, or in what quantities it may be used. Forkin classifies it as “Restricted use” and does not make health claims. See the methodology for how regulatory levels are assigned, or the guide to how EU additives are approved, re-evaluated and banned.
Is E227 vegan or vegetarian?
Calcium bisulphite (E227) is typically produced from plant, mineral, or synthetic sources, so it is generally suitable for vegans and vegetarians.
E227 belongs to the sulphite group (E220–E228). Sulphites are one of the 14 EU-declarable allergens: above 10 mg/kg or 10 mg/L the label must state ‘contains sulphites’, whatever the additive's technological purpose.
The production source can vary between manufacturers — the Forkin app shows product-specific vegan and vegetarian signals where available, based on ingredient and label data. Always read the label for allergens.
