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.
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 .
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 ...
Ascorbic acid efflux by embryos of dicot plants is a well-established mechanism of iron reduction and a step obligatory for iron uptake. [a] All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant and regenerator of other antioxidants. [95]
Examples of dough conditioners include ascorbic acid, distilled monoglycerides, citrate ester of monoglycerides, diglycerides, ammonium chloride, enzymes, [2] diacetyl tartaric acid ester of monoglycerides or DATEM, potassium bromate, calcium salts such as calcium iodate, L-cystine, [3] L-cysteine HCl, [4] glycerol monostearate, azodicarbonamide, [5] [6] sodium stearoyl lactylate, sucrose ...
Ascorbic acid: Found in oranges and green peppers and gives a crisp, slightly sour taste, better known as vitamin C. C 6 H 8 O 6: pH 3.59 [3] Citric acid: Found in citrus fruits and gives them their sour taste. C 6 H 8 O 7: pH 3.24 [3] Fumaric acid: Found in bolete mushrooms, Icelandic moss and lichen. Not found in fruits, used as a substitute ...
[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 ...
Many agents possessing chelating activity have been studied and used in different fields of food industry, such as citric acid, sorbic acid, polyphosphates, hinokitiol, kojic acid, EDTA, porphyrins, polycarboxylic acids, different proteins. [16] [18] Some of these compounds also have other anti-browning effects, such as acidifying or antioxidant.
