:Tartrazina
Descrizione:
Tartrazina, noto anche come E102, è un colorante azoico sintetico di colore giallo limone comunemente usato come agente colorante negli alimenti. È caratterizzato dalla sua brillante tonalità gialla ed è solubile in acqua, rendendolo adatto per varie applicazioni nell'industria alimentare e delle bevande, inclusi bibite, caramelle e prodotti da forno. Chimicamente, Tartrazina deriva dal catrame di carbone ed è noto per la sua stabilità in condizioni acide, sebbene possa degradarsi in ambienti alcalini. Ha una formula molecolare di C16H9N3NaO9S e un peso molecolare di circa 404,4 g/mol. Tartrazina è spesso utilizzato in combinazione con altri coloranti per ottenere tonalità desiderate. Tuttavia, è stato associato a reazioni allergiche in alcuni individui, in particolare quelli con sensibilità all'aspirina o asma. Le agenzie di regolamentazione, come la FDA e l'EFSA, hanno stabilito livelli di assunzione giornaliera accettabili per Tartrazina, garantendo il suo uso sicuro nei prodotti alimentari. Nonostante il suo uso diffuso, c'è un dibattito in corso riguardo ai suoi potenziali effetti sulla salute, spingendo alcuni consumatori a cercare alternative.

Tartrazine (otherwise known as E number E102, C.I. 19140, or FD&C Yellow 5) is a synthetic lemon yellow azo dye used as a food coloring. Tartrazine appears to cause the most allergic and intolerance reactions of all the azo dyes, particularly among asthmatics and those with an aspirin intolerance.

CAS:<p>Tartrazine is a yellow synthetic food dye that has been used since the late 1800s. It is classified as a non-steroidal anti-inflammatory drug (NSAID). Tartrazine binds to the response element on DNA, which inhibits gene transcription and causes cell death. The rate constant for this reaction was determined using crystalline cellulose as the substrate. Mouse monoclonal antibodies were used to measure the rate constant of transfer reactions between tartrazine and optical sensor. The optimum concentration for tartrazine was determined using toxicity studies in rats.</p>Formula:C16H9N4Na3O9S2Purezza:Min. 95%Colore e forma:PowderPeso molecolare:534.37 g/molTartrazine, 87%
