Fumaric acid natural Usage And Synthesis

Description	Fumaric acid is an important kind of organic chemical raw materials as well as the intermediate of fine chemical products. Meanwhile, it is also an important kind of derivatives of maleic anhydride, being widely used in food, coatings, resins and plasticizers. In the food industry, fumaric acid, used as souring agent, can be applied to soft drinks, western-style wine, cold drinks, fruit juice concentrate, canned fruit, pickles and ice cream. As an acidic substance used as solid beverage gas production agent, it has excellent bubble durability with delicate product organization. Fumarsyre har blitt brukt som et suringsmiddel for mat siden 1946. Som tilsetningsstoff brukes det som en surhetsregulator og kan betegnes med E-nummeret E297.Kjemisk er det en umettet dikarbonsyre og er en del av sitronsyresyklusen. Fumaric acid is a common food additive included in many processed foods to keep them stable and to add tartness. The substance has a more sour flavor than citric acid, another common food additive. Fumaric acid occurs naturally in fumitory, bolete mushrooms, lichen and Iceland moss. As an additive, fumaric acid is produced synthetically, mainly from malic acid from apples. Fumaric acid as an additive is regulated under the Codex Alimentarius General Standard for Food Additives (GSFA), a collection of internationally recognized standards.The U.S. Food and Drug Administration considers it safe.
Kjemiske egenskaper	Fumaric acid is naturally presented in Corydalis, mushrooms and fresh beef. Product precipitated from the water is monoclinic needle-like, prismatic or leaf-like white crystalline or crystalline powder. It is odorless with a special and strong sour, which is about 1.5 times that of the citric acid. It has a melting point 287 ° C, the boiling point of 290 ° C with subjecting to sublimation at temperature above 200 ° C. When being heated to 230 ° C, it will lose water and become maleic anhydride. Its co-boiling with water can produce DL-malic acid. It is soluble in ethanol, slightly soluble in water and ether, but insoluble in chloroform. The pH value of the 3% aqueous solution is 2.0 to 2.5 with a strong buffering performance, in order to maintain the pH of the aqueous solution at around 3.0. This product is non-toxic; rat-oral LD50: 8000mg/kg.
Chemical Properties	Fumarsyre er et fargeløst til hvitt, luktfritt krystallinsk pulver. Fruktig-sur smak.
Kjemiske egenskaper	Fumaric acid occurs as white, odorless or nearly odorless, granules or as a crystalline powder that is virtually nonhygroscopic.
Chemical Properties	White, odorless granules or crystalline powder. It is soluble in alcohol, slightly soluble in water and in ether, and very slightly soluble in chloroform. Fumaric acid is used as a replacement for tartaric acid. It has an odorless, tart, acidic-sour flavor. It may be synthesized by the action of certain fungi (Rhizopus nigricans) on glucose; by oxidation of furfural with sodium chlorate in the presence of vanadium pentoxide.
Kjemiske egenskaper	Fumaric acid is odorless with a tart, acidic-sour favor Fumaric acid is used as a replacement of tartaric acid.
Occurrence	Rapportert funnet i flere planter, Fumaria offcinalis L, Boletus scaberBoll og lean raw fsh
Uses	fumarsyre brukes til å tilføre produkter duft og redusere pH. Det kan også bidra til å holde pH stabil. Det brukes vanligvis i rensemidler. Fumarsyre forekommer naturlig i planter, som lav og ismos, og hos dyr. For eksempel produserer huden fumarsyre som er utsatt for lys. Den kan også F produseres syntetisk.
