Caution

Sometimes. This ingredient could be derived from animal sources but is not usually seen in food (more typically seen in medications, supplements, cosmetics and/or cleaning supplies).

Gluconolactone and the Pescatarian Diet

Gluconolactone is a polyhydroxy acid derived from gluconic acid, which is naturally present in fruits and honey. It is primarily used in cosmetics and skincare products for its exfoliating and moisturizing properties. In the food industry, it acts as a sequestrant, acidifier, or preservative, though its use in foods is less common compared to its prevalence in non-food products.
