| Abstract: | Extractability in various solvents of grape skin proteins from cv Palomino, the most abundant and characteristic grape in the sherry zone, was studied. The greatest extractability was obtained in NaOH solutions. Amino acid analysis of the various protein extracts showed that the most abundant amino acid was glutamic acid and the limiting ones were tryptophan and the sulphur-containing amino acids, methionine and cystine. |
