Sauerkraut with the Addition of Lactobacillus casei: Effects of Salt and Sugar Concentrations on Fermentation and Antioxidant Activity

This study developed sauerkrauts with the addition of Lactobacillus casei and investigated how salt and sugar concentrations affected their fermentation and antioxidant activity. Methods: A fresh cabbage was washed and cut, before salt (1.0%; 1.5% and 2.0%) and sugar (0% and 2.0%) were added, prior to inoculation with a L. casei culture at 10% (v/w). The cabbage was then incubated at 28oC for 5 days. The controlled lactic fermentation of the cabbage without culture and sugar, but with salt at 2.5% was performed. The sauerkrauts were evaluated for total lactic acid bacteria, pH, total acidity, phenolic content and DPPH scavenging activity. Results: The fermentation increased the total lactic acid bacteria counts in the sauerkrauts from 1.38 x 109 to 3.86 x 109 cfu/mL, and this demonstrated significant (p
