Sparkling Wine

Comparative study was conducted on the basis of free amino acids and biogenic amines of Hungarian sparkling wines originated from 3 producers (Törley, Hungária, Balaton Boglár). Determination of amino acids and biogenic amines was accomplished by ion-exchange chromatography using an amino acid analyser. The dominant free amino acids in sparkling wines were proline and arginine and the major biogenic amine was spermidine. Based on results of chemometric analyses, free amino acid and biogenic amine contents seemed to be closely related to quality and the technology of sparkling wine making.

Amino Acid Analyser

Determination of the composition of proteins by amino acid analysis after hydrochloric acid hydrolysis is unsatisfactory for cystine which is not all recoverable. When proteins were hydrolysed in hydriodic acid, half-cystine was released quickly and without measurable loss as cystine with freshly distilled acid and as cystine plus cysteine with hydriodic acid containing hypophosphorous acid_ The necessary alterations to the normal operating conditions of an amino acid analyser to enable the resolution of cysteine from proline are discussed. This procedure for cystine analysis provides a simple alternative to determinations involving chemical modification of the amino acid.
