201 Sodium Sorbate

What is Sodium sorbate (201), and where is it used?

Sodium sorbate, also known as E201, is a food preservative commonly used in the food and beverage industry to prevent the growth of bacteria, yeast and moulds [1]. This additive is the sodium salt of a naturally occurring compound known as sorbic acid. While sodium sorbate can be sourced naturally, it’s most commonly synthetically produced. The main purpose of sodium sorbate as a food preservative is to prevent microbial growth, thereby maintaining the quality, taste, texture and shelf-life of various products, such as wine, carbonated drinks, fruit juices, salad dressing, cottage cheese, meat and fish products [1,2]. 

Purported Health Implications

While sodium sorbate itself may not have explicit health benefits as a preservative, its capacity to prevent microbial growth and safeguard the nutritional value contributes to upholding the overall quality and safety of products, thereby reducing the risk of food-borne illnesses [1,2].

  • Allergic Reactions: Some individuals may experience allergic reactions or sensitivities to preservatives, including sodium sorbate. This may include skin rashes, hives or respiratory symptoms [2]. If you suspect or have a known allergy to sodium sorbate, it’s important to be aware of its presence in food products and to consult a healthcare professional.

  • Potential Genotoxicity: Previous investigations have shown conflicting results, in which some studies reported that sodium sorbate might have harmful effects on genes in cultured Hamster cells and isolated human lymphocytes [3-5]. Whereas, other studies have reported no genotoxicity was found in mice or hamsters [6]. 

 Recommendations for Safe Consumption

  • Acceptable Daily Intake (ADI): The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the EU Scientific Committee for Food (SCF) both have allocated a group ADI for sorbic acid (E200) and its sorbates, including sodium sorbate (E201), of 25 mg/kg body weight/day [7,8]. Adhering to recommended limits is key to ensuring safe consumption.

  • Balance diet with fresh foods: Just like any food additive, moderation is key. Although sodium sorbate is an effective preservative, it's important to have a diverse and balanced diet that includes fresh, minimally processed foods. Depending solely on preserved or processed foods may not supply all the necessary nutrients our bodies require for overall well-being. Incorporating a variety of fresh foods into your diet reduces the need for preserved foods.

  • Different Legalisations: Due to concerns about the potential genotoxic and mutagenic effects of sodium sorbate, it has been prohibited as a food additive in the UK and throughout Europe by the European Union [9]. Whereas, it is a permitted additive in the US, Australia and New Zealand [10,11].

  • Regulatory Agencies: The FDA has determined sodium sorbate as “Generally Regarded As Safe” (GRAS) when used in accordance with good manufacturing practices [10].
