Influence of Apple Juice Type on Fermentation Process and Volatile Compounds of Hard Apple Cider

| Summary: | Fermented apple cider is a refreshing alcoholic drink known since ancient times, and it is obtained by fermenting apple fruit juice. Using the standards of alcohol concentration (up to 8%) and carbonation, it belongs to drinks similar to beer. It can be produced using wild yeasts, but currently a fermentation starter can be purchased. This work aims to produce fermented cider using commercial pasteurized juices: clear apple juice and organic cloudy juice using commercial yeast for cider production. After fermentation, the physico-chemical characteristics of the drink were determined, alongside volatile compounds of the freshly produced ciders, as well after 1, 2, and 3 weeks of maturation. Acids, alcohols, carbonyl compounds, terpenes, esters, and volatile phenols were determined using headspace–solid phase microextraction–gas chromatography–mass spectrometry (HS-SPME-GC/MS). The results show that the fermentation was slower (14 days) in the cloudy juice in contrast to the sample produced from clear apple juice (10 days). Also, the volatile compounds related to aroma were abundantly found in the cider produced from cloudy apple juice compared to the cider produced from the clear apple juice. The conducted sensory analysis was in favor of cloudy juice. |
