摘要

The performance of different selected yeast strains regarding the capacity to convert histidine into histaminol during fermentation has been described and discussed in a model grape must (Chardonnay). First, the activity of 10 commercial active dry yeast strains (ADY) in the native grape must both with and without a nitrogen supplementation has been compared. In the second set of fermentations, after selecting the four best-performing strains, their performances using four different nitrogen sources have been tested. During fermentation process it was not possible to identify a common trend. In some cases, histaminol content appeared related to the nutrient supplementation, however, in other cases a different behaviour emerged. However, as shown by the experimental evidences, among the two variables considered the nature of yeast strain was slightly prevalent.
