Ascorbic Acid 500g is a professional-use food antioxidant and acidulant developed for chefs, pastry kitchens, mixologists, beverage developers, and food manufacturers who need to reduce oxidation, inhibit browning, and manage acidity with precision.

Ascorbic acid is used in food and drink to help preserve freshness, protect colour, and extend usable life by reducing oxidation and browning.

Made from pure ascorbic acid (E300), this fine off-white crystalline powder dissolves easily and can be added directly to liquids, purées, syrups, and other cold or post-cooking preparations. In practical use, it helps slow enzymatic browning in cut fruit and vegetables, reduces oxidation in juices and clarified liquids, and supports cleaner flavour retention in ingredients that are easily dulled by air exposure.

It delivers effective antioxidant protection while maintaining a clean, light acidity that does not dominate the final flavour profile. At lower use levels, it is primarily valued for freshness protection and colour preservation. At higher levels, it can also contribute a mild sourness, support pH balancing in cocktails, jams, and beverages, and add Vitamin C enrichment to finished products.

Compared with citric acid, ascorbic acid is used more for its antioxidant and anti-browning function than for assertive acidity. Where citric acid is typically chosen to create a sharper, more direct sour profile, ascorbic acid is often selected when the goal is to preserve freshness, protect colour, and add only a gentler acidic profile.

Suitable for fruit and vegetable preparation, juices, smoothies, cocktails, clarified liquids, jams, syrups, cold sauces, purées, and other oxidation-sensitive food and beverage applications.

For best results, add directly to the liquid or preparation during cold prep, immediately after cutting or juicing, or after cooking once the product has cooled sufficiently. Typical usage is 0.02% to 0.2%, with lower levels used for antioxidant protection and higher levels used where acidity or Vitamin C fortification is also required.

We will always contact you to confirm these additional fees before we accept and process your order.
Please note the website does not calculate or charge local import taxes or customs duties for non-UK destinations. You are liable for payment of these if they arise.
