Abstract
Major characteristics of waste brine from the repeated salting and rinsing processes of Chinese cabbage for Kimchi were investigated. Salt concentration of brine was increased with the number of successive salting steps from 12% after 1st salting step to 14% after 5th step. Total waste brine which is the representative of wastewater produced from salting process of cabbage showed 6-8% salt concentration. The pH values in all samples decreased with the number of reuse of brine and showed pH 5.9 and pH 5.2 for the mixture of brine for quarter-cut and small-cut cabbage, respectively, after 5th salting process. Soluble solid contents increased with repetition and resulted in 14-16
