Quality Characteristics of Low-Salted Yacon Pickles with Leaf-mustard and Pepper

The rate of salt and sugar into pickled cabbages was determined, and physicochemical characteristics, such as sensory, texture, and pH, of vinegar pickled cabbages during storage were examined at different storage temperatures and vinegar concentrations. The rate of salt and sugar penetration was faster in smaller size and on leaves rather than the stem of cabbage. Also, higher salt and sugar concentration and higher storage temperatures led to increase in salt and sugar permeation rate. As a result of sensory test, lower storage temperature is the most suitable, and 6% vinegar concentration was the mostly appropriate. Hardness and cohesiveness were decreased significantly at the initial 1st week storage time, but storage temperature did not show any significant effect. Addition of vinegar contents enhanced the hardness, but decreased cohesiveness. The pH was lowered with increasing vinegar content, indicated most significant factor on pickled cabbage. In general, salt and sugar contents rather than storage temperature have greater influence on permeation rate, and especially, addition of vinegar affects the texture of pickled cabbage.
