Ascorbic acid is a weak sugar acid structurally related to glucose. In biological systems, ascorbic acid can be found only at low pH, but in solutions above pH 5 is predominantly found in the ionized form, ascorbate. [8] Numerous analytical methods have been developed for ascorbic acid detection.
Irwin Stone (1907–1984) was an American biochemist, chemical engineer, and writer.He was the first to use ascorbic acid in the food processing industry as a preservative, and originated and published the hypothesis that humans require much larger amounts of Vitamin C for optimal health than is necessary to prevent scurvy.
Ascorbic acid is an organic compound with formula C 6 H 8 O 6, originally called hexuronic acid. It is a white solid, but impure samples can appear yellowish. It ...

His 1955 thesis was "studies on ascorbic acid synthesis in apple leaves" (Cornell: 1955, 304 pages). In 1960, while working for the Canadian Department of Agriculture in Ottawa (Agriculture Canada), he developed a process of making instant mashed potato flakes, and filed a patent on the process (Canadian patent 3260607, July 1966).
Intravenous Ascorbic Acid or PAA, pharmacologic ascorbic acid [1] (also known as vitamin C or L-ascorbic acid), is a process that delivers soluble ascorbic acid directly into the bloodstream. It is not approved for use to treat any medical condition.
The Reichstein process in chemistry is a combined chemical and microbial method for the production of ascorbic acid from D-glucose that takes place in several steps. [1] This process was devised by Nobel Prize winner Tadeusz Reichstein and his colleagues in 1933 while working in the laboratory of the ETH in Zürich.
