[Proportion of proline in wines from province of Trapani produces in 1973/74 and 1974/75 years, determinated with changed Ough's method (author's transl)].

Abstract

The proportion of proline in tested wines, has given values between 670 and 1110 mg/1, with 920 mg/1 on an average. The tests have been executed with Ough's method replacing the mixture Isopropanolo diluited 1 : 1 by water, with N-Butanolo, by which we have obtained the best reproductivity of values in time.
