Sodium formate

International Numbering System (INS) for Food Additives: 237

Food additives Europe numbers: E237 

Sodium formate (E237) is a multi-functional food additive that shows up in various processed foods. Here's a breakdown of its key aspects:

Functions:

• Preservative: The primary function of sodium formate in food is to inhibit the growth of bacteria and mold, thereby extending shelf life [1]. This is beneficial for products like baked goods, cheeses, and some meats.
• Acidity regulator: Sodium formate can help control the acidity of some foods, which can impact taste, texture, and overall quality [2].

Additional benefits:

• Antimicrobial properties: Along with preventing spoilage microbes, sodium formate may also have some activity against certain foodborne pathogens [3]. However, more research is needed to confirm this fully.

Applications:

• Variety of processed foods: You might encounter sodium formate in bakery items (cakes, breads), cheeses, some processed meats, beverages (like soft drinks or beer), and even certain dried fruits or vegetables [4].

Safety:

• Generally recognized as safe (GRAS): Regulatory bodies like the US FDA and the European Food Safety Authority (EFSA) consider sodium formate safe for its intended uses when consumed within established limits [5, 6].

Overall:

Sodium formate is a common food additive that acts as a preservative and acidity regulator in various processed foods. It contributes to extending shelf life and potentially enhancing food safety. While generally safe, if you have any concerns about food additives, it's always best to consult a healthcare professional or registered dietitian for personalized advice.
