Sodium Erythorbate

International Numbering System (INS) for Food Additives: 316

Food additives Europe numbers: E316 
Sodium erythorbate is a food additive with a few key functionalities that come in handy for processed meats and other products. Here's a closer look at its roles:

Main functions:

• Antioxidant: Similar to vitamin C in structure, sodium erythorbate helps prevent spoilage by slowing down the oxidation process in foods [1]. This helps maintain freshness and flavor.
• Color fixative: In cured meats like hot dogs, ham, and bacon, sodium erythorbate plays a vital role in preserving the appealing pink color [2]. It aids in the conversion of nitrite, another curing agent, to nitric oxide, which is responsible for the characteristic pink hue.
• Flavor enhancer: Studies suggest it can maintain and even improve the flavor profile of cured meats by reducing off-flavors that can develop during processing [3].

Additional benefits:

• Reduces nitrosamine formation: Nitrosamines are potentially carcinogenic compounds that can form during meat curing. Sodium erythorbate helps minimize their formation by enhancing the effectiveness of nitrite at lower levels [4].

Safety:

• Generally recognized as safe (GRAS): Both the US Food and Drug Administration (FDA) and European Food Safety Authority (EFSA) consider sodium erythorbate safe for its intended uses when consumed within acceptable amounts [5, 6].

Where you might find it:

• Processed meats: Most common in cured meats like hot dogs, sausages, bacon, ham, and corned beef.
• Other uses: Sometimes used in poultry, fish, and even certain beverages like soft drinks to prevent oxidation and improve shelf life.

Overall:

Sodium erythorbate is a versatile food additive that acts as an antioxidant, color fixative, and flavor enhancer in processed meats. It also offers the benefit of reducing potentially harmful nitrosamines. While generally safe, if you have any concerns, it's always best to consult a healthcare professional.
