CAS 77-92-9

Acido citrico

Descrizione:

Acido citrico, con il numero CAS 77-92-9, è un acido organico debole che si trova naturalmente negli agrumi. È una sostanza cristallina e incolore che è altamente solubile in acqua, rendendolo un acidificante efficace in varie applicazioni alimentari e di bevande. Acido citrico ha un sapore aspro ed è comunemente usato per esaltare il sapore, conservare gli alimenti e agire come stabilizzatore di pH. La sua formula molecolare è C6H8O7 e contiene tre gruppi di acidi carbossilici, che contribuiscono alla sua acidità. Oltre ai suoi usi culinari, Acido citrico è utilizzato in prodotti farmaceutici, cosmetici e per la pulizia grazie alle sue proprietà chelanti, che gli permettono di legarsi agli ioni metallici. Svolge anche un ruolo nel ciclo di Krebs, una via metabolica cruciale negli organismi viventi. Acido citrico è generalmente riconosciuto come sicuro (GRAS) dalle agenzie regolatorie, rendendolo una scelta popolare in vari settori. La sua natura biodegradabile ne aumenta ulteriormente l'attrattiva come opzione ecologica.

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.
