Scallion Storage Technology Optimum Storage Temperature: 0°C Relative Humidity: 95% RH or more Onion is also a common leafy dish, suitable for storage in low temperature and high humidity environments. Above freezing point, the lower the storage temperature, the better (around 0°C). The relative humidity is preferably 98-100% RH. Therefore, it can be placed in a hole-opening plastic bag. Shallots are truncated before bandaging to avoid bringing large amounts of waste to the market. If you pay attention to maintaining hygienic conditions and avoid invasion of pathogenic bacteria during truncated, the storage period of truncated or not has little difference. Commercially available ones may choose to use truncated or not truncated, as appropriate. Storage temperature (°C) 0 5 10 15 Room temperature (25°C) Storage period (days) 18-26 10-14 6-10 4-6 1-2
