Is Potassium Sorbate Bad for You?
Lots of people worry if food additives like potassium sorbate are truly safe to eat. From cheese to wine, this widespread preservative shows up almost everywhere. But should we be nervous that it could harm our health? Or are those fears not based on facts?
What is a Potassium Sorbate Preservative?
Known also as k-sorbate, potassium sorbate acts as a preservative and food additive. It comes from the potassium salt of sorbic acid, a type of unsaturated fatty acid found naturally in some berries and fruits.
Definition and Chemical Composition
Having the chemical formula C6H7KO2, potassium sorbate appears as a white, odorless, crystalline powder or granular solid. It dissolves easily in water and ethanol, making it useful in liquid foods and drinks.
Production and Sources
While it can be obtained from natural sources like berries of mountain ash trees (Sorbus aucuparia), most global supply gets produced synthetically by neutralizing sorbic acid with potassium hydroxide. This reaction makes a salt highly soluble in water, which helps it work well as a preservative. It works best up to pH of 6.5, beyond which its efficacy can rapidly diminish.
The solubility and stability of potassium sorbate make it very effective in acidic environments, which is why it is commonly used in acidic foods and drinks. This property ensures that potassium sorbate preservative distributes evenly throughout, providing effective protection from spoilage.
Potassium Sorbate Applications
Using potassium sorbate as a preservative relies on its ability to stop molds, yeasts, and some bacteria from growing. This extends shelf life of many foods, personal care products and cosmetics. Some examples where you’ll find Potassium Sorbate include:
- Baked goods like bread, cakes and pastries
- Cheese and other dairy products
- Dried fruits and vegetables
- Wine and other alcohol
- Jams, jellies and syrups
- Processed meat and fish
- medications and creams
Besides using potassium sorbate in food, it also works as a preservative in shampoos, lotions and cosmetics.
Is Potassium Sorbate Bad for You?
A common question that people often ask: Is potassium sorbate safe?
Yes, Potassium Sorbate as an additive has been thoroughly assessed and approved as safe by reputable regulatory groups. The U.S. Food and Drug Administration (FDA) gives potassium sorbate a Generally Recognized As Safe (GRAS) status, meaning it is safe for consumption when used in proper amounts. This preservative also has regulatory approval from global bodies like United Nations Food and Agriculture Organization and European Food Safety Authority (EFSA), further confirming its safety for human intake.
World Health Organization (WHO) sets the Acceptable Daily Intake (ADI) of potassium sorbate at up to 25 mg/ kg of body weight. This allows an average adult weighing 70 kg to safely have 1750 mg of it daily, without ill effects. Due to its effectiveness at preventing mold, yeast and fungus growth, to prolonging shelf life, this preservative is widely used in apple cider, baked goods, cheeses, dried meats and more.
Possible Risks and Side Effects
Though potassium sorbate E202 is generally considered safe, rare allergic reactions can happen. Mostly this is the case with cosmetics instead of foods. These reactions can include skin irritation or rashes but aren’t very common. Environmental Working Group gives potassium sorbate low risk as a potential skin irritant.
As long as its consumption as food is concerned, potassium sorbate doesn’t accumulate in the body and harmlessly passes through in the form of water and carbon dioxide. Also, recommended concentrations for foods range from 0.025% to 0.1%. At these levels, no adverse health effects are known.
1970s rat studies also found no carcinogenic effects from potassium sorbate.
Alternatives and Avoidance
For those who want to completely avoid synthetic preservatives, there are natural substitutes for potassium sorbate, like certain flavonoids. However, potassium sorbate has a 50+ year track record as a reliable, safe choice, with extensive research on its safety and use as a preservative.
Conclusion
To wrap things up, potassium sorbate is a widely accepted preservative. It’s important in stopping food and personal care products from going bad and helps them last longer. Scientific studies and regulatory bodies back its safety. Therefore it’s okay to consume it as long as we stick to the recommended amounts.
