Comparison of quality characteristics between seasonal cultivar of salted-Kimchi cabbage (Brassica rapa L. ssp. Pekinesis)

Abstract

This study was carried to investigate the physicochemical and microbiological characteristics of seasonal salted-Kimchi cabbage order to provide basic data for optimal salting and storage condition of seasonal Kimchi cabbage. Generally, fall season samples had slightly higher pH and acidity value than the other seasonal salted Kimchi cabbage. The soluble solids content of spring, summer, fall and winter samples were 5.95%, 6.18%, 6.29% and 7.76%, respectively. The salt content of all the seasonal salted Kimchi cabbage samples were insignificant. The number of microbial bacteria in the summer samples were generally much more significant than spring and winter samples. There was no significant difference in the color of seasonal salted Kimchi cabbage. As for the texture properties, the firmest samples in the surface rupture test were the spring samples (force: 4.92 kg), and the hardest samples in the puncture test were the summer samples (force: 11.71 kg). In the correlation analysis of the quality characteristics of seasonal samples, the soluble solids content and hardness of the seasonal salted Kimchi cabbage was significantly correlated at 1% significance level. Also, in the principal component analysis, F1 and F2 were shown to explain 27.28% and 35.59% of the total variance (62.87%), respectively. The hierarchical cluster analysis of the quality characteristics of seasonal samples, the samples were divided into three groups: spring cabbage group, summer cabbage group and fall and winter cabbage group,.

“…Therefore, we analyzed the Pearson's correlation coefficient (23,24) between the temperature changes in the materials according to the transport system and the quality characteristics to determine the quality index for the distribution of salted Korean cabbage (Table 2). The correlation coefficients between a CVS without salt water and salinity, acidity, or yeast and mold were 0.89, 0.55 and -0.55, respectively.…”

“…It can be further classified according to its shape or form: spherical, semi-spherical and incompletely spherical. One of the optimal conditions for the growth and development of kimchi cabbage is a cool environment, which promotes a spherical shape (Ku et al, 2014;Lee et al, 2013).…”
