Zitronensäure

Beschreibung:

Zitronensäure, mit der CAS-Nummer 77-92-9, ist eine schwache organische Säure, die natürlich in Zitrusfrüchten vorkommt. Es handelt sich um eine farb- und geruchlose kristalline Substanz, die hoch wasserlöslich ist, was sie zu einem effektiven Säuerungsmittel in verschiedenen Lebensmittel- und Getränkeanwendungen macht. Zitronensäure hat einen sauren Geschmack und wird häufig verwendet, um den Geschmack zu verbessern, Lebensmittel zu konservieren und als pH-Stabilisator zu wirken. Seine chemische Formel ist C6H8O7 und es enthält drei Carbonsäuregruppen, die zu seiner Säure beitragen. Neben seinen kulinarischen Anwendungen wird Zitronensäure auch in der Pharmazeutik, Kosmetik und Reinigungsprodukten aufgrund seiner chelatierenden Eigenschaften verwendet, die es ihm ermöglichen, Metallionen zu binden. Es spielt auch eine Rolle im Krebszyklus, einem entscheidenden Stoffwechselweg in lebenden Organismen. Zitronensäure wird von den Regulierungsbehörden allgemein als sicher (GRAS) anerkannt, was es zu einer beliebten Wahl in verschiedenen Branchen macht. Seine biologisch abbaubare Natur erhöht zusätzlich seine Attraktivität als umweltfreundliche Option.

Citric Acid

CAS: 77-92-9

Applications Citric acid is a weak organic acid that is known as a commodity chemical, as more than a million tonnes are produced every year by mycological fermentation on an industrial scale using crude sugar solutions, such as molasses and strains of Aspergillus niger. Citric acid is widely distributed in plants and in animal tissues and fluids and exist in greater than grace amounts in variety of fruits and vegetables, most notably in citrus fruits such as lemon and limes. Citric acid is mainly used as an acidifier, flavoring agent and chelating agent. Citric acid is also a metabolite of Dimethyl Fumarate (D464965), a compound used as a treatment for the relapsing forms of multiple sclerosis and psoriasis.

Citric acid anhydrous

CAS: 77-92-9

Citric acid is an organic compound that is a weak organic acid. It is a colorless, odorless solid with a sour taste. Citric acid participates in many biochemical reactions, including the citric acid cycle and fatty acid metabolism. Citric acid can be found in many citrus fruits, such as lemons, limes, and grapefruits. Citric acid also has antioxidant properties and functions as an anti-inflammatory agent. Citric acid is used for the production of citrates and citrate salts, which are added to food preservatives or acidic foods such as lemonade or vinegar. Citric acid can be used to measure water vapor concentration by using fluorescence probes that react with hydrated electrons in water molecules. It also has electrochemical impedance spectroscopy (EIS) applications in biomedical research and biotechnology as an enzyme inhibitor or activator.
