A Preliminary Study on the Potential of the New Red-Fleshed ‘JB’ Clone Apple for Cider Production

Abstract

Apples are one of the most widely consumed fruits in the world, resulting in the continuous creation of new cultivars with different properties, both in terms of breeding as well as extended shelf lives and increased bioactive substance contents. This study aimed to determine the potential of a new red-fleshed apple ‘JB’ clone developed at the Warsaw University of Life Sciences to produce high-sensory-quality cider. Fermentation was carried out using the Saccharomyces cerevisiae UCLM S325 yeast strain, commonly used for quality white wines (Fermentis, Lesaffre Polska SA, Warsaw, Poland), at 15 °C for 21 days. The must and the cider were subjected to physicochemical analysis to determine their color, sugar content, total acidity, and polyphenol levels. Additionally, volatile acidity and alcohol content were measured in the cider, followed by an organoleptic evaluation. A red color characterized both the must and the cider, which had total acidities of 8.78 ± 0.05 and 6.61 ± 0.03 g malic acid/L, respectively, as well as polyphenol contents of 307.28 ± 1.29 and 240 ± 7.00 mg chlorogenic acid/L, respectively. Trained panelists evaluated the cider obtained from fermentation. The study’s results indicate that the new ‘JB’ apple clone has strong potential for producing juice and cider with a unique red color and high sensory attributes.
