Potassium bisulfate is a chemical compound that can be found as a food preservative. The chemical formula for this product is K2(SO4), and it falls into the category of a sulphite. Potassium bisulfate helps to prevent or delay food spoilage and is a class II preservative.
There are a number of uses for potassium bisulfate as a food preservative. The Manitoba Agriculture, Food and Rural Initiatives reports this product works to prevent the growth of mold, yeast and bacteria in foods. It is also an additive for homemade wine. Potassium bisulfate is found in some cold drinks and fruit juice concentrates. Sulfites are common preservatives in smoked or processed meats and dried fruits. In spray form, it may help prevent foods from discoloring or browning.
Potassium bisulfate is primarily a commercial product. You might find this chemical compound at meat processing plants. Manufacturers of juice drinks and concentrate will use potassium bisulfate to increase the shelf life of their products. The preservative is also available for home use. You can purchase potassium bisulfate at stores and online retailers that market wine-making products.
Sulphites such as potassium bisulfate can trigger an attack for those with asthma. According to Dr. Adrian Morris, potassium bisulfate may cause lung irritation. Other chemicals that fall into this category include sulphur dioxide, sodium sulphite and potassium metasulphite.
The Royal Society for the Prevention of Cruelty to Animals (RSPCA) in Australia claims some preservative may cause health problems for pets. On this list is potassium bisulfate. According to the RSPCA, products with labels such as "pet meat" or "pet food rolls" may contain this preservative. Potassium bisulfate can lead to thiamine (vitamin B1) deficiency in dogs and cats. This condition may cause severe neurological problems and death for animals.
If after eating processed meat or another food that may contain potassium bisulfate, you feel ill, have shortness of breath or develop hives or a rash, this may be an indicator of an allergic reaction to the chemical. Seek medical care immediately. Do not serve homemade wine containing potassium bisulfate to anyone with asthma without warning him first. Check labels of pet foods to ensure the product does not contain potassium bisulfate or other sulfide preservatives. The regulations for labeling may differ between states. According to the United States Food and Drug Administration (FDA), pet food labeling is monitored at both the federal and state levels. Most will list preservatives in the ingredients. Manufacturers must adhere to specific preservatives approved by the FDA. Labeling may vary between countries as well. In Australia, it is not a legal requirement that pet foods list preservatives on their labels. If you are concerned, talk to your vet about the best food choices for your pet
