Özet
Shalgam has been a fermented beverage produced in high amounts and consumed widely in Turkey in recent years. Despite its potential, there is no specific processing method or temperature for the production of shalgam beverages. Therefore, in this study, some changes in shalgam obtained by using two production processes (conventional and rapid processes) at 25 and 35°C were monitored during 4 months of storage. In particular, changes in color values that might affect product quality and attractiveness were influenced by production method, temperature and storage time. The highest a* and b* color values were found in samples produced by using the rapid process at 25°C (5.61 and 0.12, respectively) while the lowest values were found in those manufactured by the conventional method at 35°C. The L* values of beverages changed by storage time. In addition, while the content of anthocyanins decreased by storage time, the content of total antioxidants increased. Additionally, when production temperatures were compared, total aerobic mesophilic bacteria counts in shalgam beverages were higher at 35°C than 25°C. All samples produced at two different temperatures and with two different methods showed a decrease in the number of lactic acid bacteria at the end of storage time. Considering all the changes, it could be concluded that it would be inappropriate to store shalgam beverages at room temperature for 4 months or longer without using any heat treatment or preservative. © 2022 by the authors.
