Per soddisfare la crescente domanda di cibo da parte della popolazione umana in continuo aumento, la carne coltivata (chiamata anche carne in vitro, carne artificiale o carne coltivata in laboratorio) viene presentata dai suoi sostenitori come una buona alternativa per i consumatori che vogliono essere più responsabili ma non vogliono modificare la loro dieta.
Questa review vuole aggiornare le conoscenze attuali su questo argomento, concentrandosi su pubblicazioni recenti e su aspetti non ben descritti in precedenza. La conclusione principale è che non sono stati osservati grandi progressi nonostante le molte nuove pubblicazioni. Infatti, in termini di questioni tecniche, è ancora necessaria la ricerca per ottimizzare la metodica di coltivazione cellulare.
Inoltre, è quasi impossibile riprodurre la diversità delle carni provenienti da varie specie, razze e i differenti tagli.
Sebbene i benefici non siano ancora noti, sono stati ipotizzati quelli potenziali in termini di salute e gli svantaggi della carne coltivata.
A differenza della carne convenzionale, le cellule muscolari sviluppate in coltura possono essere più sicure, non avendo organi digestivi adiacenti. D’altra parte, a causa di questo elevato livello di moltiplicazione cellulare, è probabile una certa disregolazione come succede per le cellule tumorali. Allo stesso modo, non è ancora chiara la regolazione della sua composizione nutrizionale, soprattutto per quanto riguarda i micronutrienti ed il ferro ...
