Un nuovo tipo di alimento dal sapore "fantascientifico" è pronto per essere immesso sul mercato: carne che non è mai cresciuta su un animale vivente, ma creata in laboratorio da una base di cellule staminali estratte da polli "veri".
Un’azienda americana ha in programma di vendere (e sarà la prima in assoluto) questo prodotto negli Stati Uniti già a partire dal 2019. Secondo i produttori, questo metodo è più rispettoso del clima ed evita i problemi etici di macellazione di animali.
Carne "coltivata"
Disse Winston Churchill in un'intervista nel 1931: "Sfuggiremo all'assurdità di far crescere un pollo intero, solo per mangiarne il petto o l'ala, facendo crescere queste parti separatamente in un ambiente adatto". E infatti, nel XXI secolo, diversi progetti di ricerca sono riusciti nella produzione di carne in vitro (o carne "coltivata" o "pulita") nei laboratori. Il primo hamburger in provetta, creato da una squadra olandese, è stato mangiato ad una dimostrazione per la stampa a Londra ad agosto del 2013.
