Quality Estimation of Winter Chinese Cabbage Stored in Purge Type of Controlled Atmosphere Storage

Abstract

This study was conducted to propose the conditions of controlled atmosphere (CA) storage suitable for the storage of winter Chinese cabbage and to investigate the maximum storage period of Chinese cabbage based on the results of the quality analysis for CA storage. The weight loss rate of Chinese cabbage stored at 194 days in low temperature storage was about 2 times higher than that in CA storage. The trimming loss rate of Chinese cabbage stored at low temperature was 1.5 times higher than that of CA storage after 83 days of storage. Bolting of Chinese cabbage was observed in only low temperature storage. The Chinese cabbage firmness of CA storage was not different in the range of 5.7-6.2 N, while low temperature storage gradually increased after 83 days of storage and was 7.5 N at 194 days. The incidence of mold occurred after 83 days in low temperature storage, while in CA storage it occurred after 153 days. In the quality evaluation, CA storage for Chinese cabbage was rated 1.5-1.9 points higher than the low temperature storage. The maximum storage period of Chinese cabbage at low temperature storage was 83 days and that at CA storage 153 days.

Effects of Environmental Changes by an Agrivoltaic System on Growth and Quality Characteristics of Kimchi Cabbage

“…At 16 weeks after planting, 10 specimens harvested from 4 cultivation points for each plot were compared in terms of growth, quality and storage characteristics according to the standard of analysis and survey for agricultural science and technology (RDA, 2012; hereinafter referred to as the Standard). The terms used hereinafter are defined as follows: the "plant" for intact specimens immediately after being harvested with the roots cut off; "trimming" for the operation of removing the outer leaves damaged by drying or decay; and the "head" for the inner part remaining after selection (Lee et al, 2016;Kim et al, 2018).…”
