Mineral ascorbates are used as dietary supplements and food additives, and drugs. An example of a mineral ascorbate drug is sodium ascorbate injections (the acid form, ascorbic acid, of vitamin c is too acidic for injections). Ascorbate salts may be better tolerated by the human body than the corresponding weakly acidic ascorbic acid.
Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium). As a food additive, it has the E number E301 and is used as an antioxidant and an acidity regulator. It is approved for use as a food additive in the EU, [3] USA, [4] Australia ...
Vitamin C (ascorbic acid) is a water-soluble compound that fulfills several roles in living systems. Sources include citrus fruits (such as oranges , sweet lime , etc.), green peppers , broccoli , green leafy vegetables , black currants , strawberries , blueberries , seabuckthorn , raw cabbage and tomatoes .
It is the potassium salt of ascorbic acid and a mineral ascorbate. As a food additive, it has E number E303, INS number 303. Although it is not a permitted food additive in the UK, USA and the EU, [2] [3] it is approved for use in Australia and New Zealand. [4]
Ascorbic acid and its sodium, potassium, and calcium salts are commonly used as antioxidant food additives. These compounds are water-soluble and, thus, cannot protect fats from oxidation: For this purpose, the fat- soluble esters of ascorbic acid with long-chain fatty acids (ascorbyl palmitate or ascorbyl stearate) can be used as antioxidant ...
And that can include everything from ascorbic acid (aka vitamin C), which helps keep foods fresh, to iodine, which was added to salt in the 1920s to help combat iodine deficiency in the general ...
ascorbic acid [20] (Ascorbic acid converts into its oxidizing form, dehydroascorbic acid (DHAA) during mixing.) azodicarbonamide (E927) potassium bromate (E924, the component which gives bromated flour its name, used mainly in the U.S. East and Midwest, acts as a bleaching agent, banned in some areas) potassium iodate
[35] [94] While ascorbic acid is effective antioxidant, it can also oxidatively change the flavor and color of food. With the presence of transition metals, there are low concentrations of ascorbic acid that can act as a radical scavenger in the Fenton reaction. [93] 2 Fe 3+ + Ascorbate → 2 Fe 2+ + Dehydroascorbate 2 Fe 2+ + 2 H 2 O 2 → 2 ...
