Abstract

Gli obiettivi di questo presente lavoro sono caratterizzare le caratteristiche fisico-chimiche, le strutture chimiche mediante FTIR, sciogliere il contenuto proteico, la microstruttura e il contenuto di umidità del caseinato di potassio preparato con metodi di essiccazione e forza acida. L'esperimento è stato organizzato secondo un disegno fattoriale randomizzato completo con triplicati, mentre i dati dell'analisi FTIR e della microstruttura sono stati presentati descrittivamente. I risultati hanno mostrato che gli acidi ei metodi di essiccazione per la preparazione del caseinato di potassio potrebbero aumentare l'attività antiossidante, punteggio a * (rossastro), punteggio b * (giallastro). In particolare, il metodo di liofilizzazione abbinato a trattamenti acidi ha rappresentato la riduzione del contenuto di umidità, ma ha consentito di migliorare la viscosità e le proprietà microstrutturali. In breve, potremmo sostenere che le tecniche di essiccazione e gli acidi hanno mostrato effetti evidenti sulla qualità del caseinato di potassio.
