Sodium disulfite
Sodium disulphite, also known as sodium pyrosulphite or sodium metabisulphite, is a sodium salt of disulphurous acid, which is not stable in free form. It has the molecular formula Na2S2O5 and is designated as a food additive with the number E 223.
Why is sodium disulphite used in food?
Sodium disulphite is mainly used as a preservative and antioxidant. It prevents the growth of microorganisms and the loss of color and flavor through oxidation. It is used in dried fruit, horseradish paste, fruit and vegetable preparations, seafood, potato dishes, ready meals, fruit juices and jams.
How does sodium disulphite affect dogs?
In most people and dogs, sodium disulphite is quickly broken down by the body's own enzyme in the concentrations found in food. However, it can lead to nausea, vomiting, diarrhea and headaches if ingested in large quantities.
In asthmatics, sodium disulphite can trigger sulphite asthma; allergic and allergy-like reactions are also possible, although rare. These reactions can manifest themselves in dogs in a similar way to humans, for example through breathing difficulties, itching, skin rash or shock.
How can sodium disulphite be avoided?
Sodium disulphite must be declared on food packaging if it is used as an additive. You can therefore make sure that you do not buy or feed products that contain E 223. You should also make sure that you do not give your dog any food that is intended for humans and may contain sodium disulphite, for example dried fruit or ready meals.
Sodium disulphite is a food additive used as a preservative and antioxidant. It can lead to intolerances or allergic reactions in humans and dogs if it is ingested in large quantities or if there is a sensitivity. You can avoid it by paying attention to the list of ingredients in food or only feeding your dog fresh or home-prepared food.
If you notice any signs of hypersensitivity or poisoning in your dog, you should see your vet immediately. We are not a substitute for a vet, but we try to be as accurate as possible. Every dog reacts differently and we recommend you get a second opinion or consult your vet if in doubt.
Stay healthy and take good care of your four-legged friend!😊
