Effect of seasonal cabbage cultivar (Brassica rapa L. ssp. Pekinesis) on the quality characteristics of salted-Kimchi cabbages during storage period

Abstract

This study investigates the physicochemical, microbiological and sensory characteristics of seasonal salted-Kimchi cabbages to provide basic data on its uniform quality. Generally, seasonal salted-Kimchi samples had different pH values at initial storage periods, but there was no difference in pH between the seasonal samples when stored for longer periods. The samples from the fall and winter seasons were relatively low in acid and high in solid soluble content compared to samples from other seasons. Salted-Kimchi cabbages in the summer showed the highest microbiological number compared to samples from other seasons. In the sensory evaluation, there were differences in the appearance, aroma, and taste, depending on seasonal samples at different storage periods. The correlation coefficient between the quality characteristics in the seasonal samples showed a positive or negative correlation between the quality characteristics at 1% significant level. In the principal component analysis, F1 and F2 were shown the 51.81% and 14.23% of the total variance (66.21%), respectively. In the PCA pattern of seasonal salted-Kimchi cabbages during storage periods, winter samples were distributed on the top of F2, spring samples were in the middle of F2, while the rest of the samples were distributed on the bottom of F2. According to increasing storage periods, initial storage samples were distributed at the left of F1, while other samples were located at the right of F2.

“…특히, 비타민 B1이 많이 함유되어 있어 면역력을 강화하고, 알코올 흡수 저해 효과 및 항산화 효과가 있다 (Chung & Jung, 2003). 봄동(Brassica rapa L.)은 십자화과(Brassicaceae) 배추 속 (Brassica)에 속하는 두해살이 잎채소 (Kim, 2016)로 겨울철 노지에 파종하고 봄에 수확하는 배추 종류 중 하나이다 (Choi et al, 2015;Seo et al, 2015). 봄동은 아미노산, 식이섬유소, 칼슘, 철분 등의 영양성분이 일반 배추에 비해 2배 가까이 풍부한 것으로 알려져 있 으며, 특히 β-carotene의 경우, 6배 이상 높은 함량을 가지고 있다 (RDA, 2016).…”
