What it is

Sodium ascorbate (E301) is the sodium salt of ascorbic acid (Vitamin C). In the food industry, it is prized as a highly soluble antioxidant that prevents food from browning and fats from going rancid.

How it is used in food

Speeds up meat curing and suppresses nitrosamine formation.

Commonly found in
  • Bacon, sausages, and cured meats
  • Minced meat and burger patties
  • Canned fruits and vegetables
  • Vitamin supplements

Health and safety

None known.

Very common in cured meats.

Alternatives to this additive

  • E300: Ascorbic acid — Pure Vitamin C, though it is more acidic and less soluble in some meat applications.

How it is made

It is typically synthesized by reacting ascorbic acid (which is often fermented from corn starch) with sodium bicarbonate (baking soda).

  1. Synthesis — Ascorbic acid is reacted with sodium bicarbonate to form a soluble salt.

Worth knowing

Vitamin C bound to sodium for better solubility.

Conclusion

In processed meats, E301 plays a vital protective role. It accelerates the curing process, meaning manufacturers can use less nitrite (E250). More importantly, it actively prevents those nitrites from forming harmful cancer-causing nitrosamines during cooking.
