Abstract

This study determined the optimal drying and storage conditions, which are regarded as crucial post-harvest management technologies, for the production of high-quality husk of ‘Saekso 5’. To determine changes in the quality characteristics of the husk according to drying temperature, samples were dried at 30°C, 50°C and room temperature (RT). Samples dried at 50°C remained free from fungal contamination, whereas the quality of samples dried at 30°C and RT significantly decreased due to fungal infection. Except for moisture, there was no difference in general component content between samples dried at 30°C and 50°C. Furthermore, there was no significant difference in Cyanidin-3-glucoside (C3G) content, which is the husk’s main quality indicator. The storage test was conducted at three different temperatures (-5°C, 5°C and RT) for six weeks. Zearalenone mycotoxin levels exceeding safe intake limits were detected after two weeks in samples stored at RT; but samples stored at low temperatures were not contaminated with fungi. Quality analysis according to storage temperature showed that the moisture content at -5°C was changed less than that at 5°C, while the C3G content was maintained for up to one week. Therefore, to produce high-quality husk of ‘Saekso 5’, a drying temperature of 50°C is more effective than 30°C. If post-harvest storage is required, the husk can be stored at -5°C for up to one week.
