Use of a Combined Autochthonous Starter to Ferment <i>Peranzana Alta Daunia</i> Table Olives

Abstract

This study aims to evaluate the use of a multiple-strain cocktail (Lactiplantibacillus plantarum, Candida norvegica, and Wickeramomyces anomalus) as a starter culture for “Peranzana Alta Daunia” olives. The effect of the veraison degree of drupes (violet or green) and brine salt concentration (6 or 8%) on the acidification kinetics was analysed by using a 2k Factorial Design. The acidification was affected by all the variables tested with the veraison degree as the most significant one; in fact, neither salt concentration nor the presence of the starter was able to improve the acidification kinetics when unripe fruits were used.
