1、 Preservation method

1. Normal temperature preservation: it is a commonly used preservation method in general families. When preserving, it should be placed in a dry and ventilated place at home. The room temperature should not be too high, and it is better not to exceed 20 ℃. Moreover, Dendrobium cannot be wrapped in outer packaging during storage, and it should not be exposed to direct sunlight. If it is stored in winter, it cannot be placed in a place too cold to avoid freezing the water

2. Refrigerated storage: if it is refrigerated in the refrigerator, it can usually be stored for 3-6 months. To put it in the fresh-keeping layer, the temperature in the refrigerator is preferably 3-5 ℃

3. Glutinous rice preservation: first stir fry the glutinous rice in the pot and wait until its color turns dark yellow. Put the Dendrobium in a glass bottle after treatment and heat it on the frying pan. Finally, put the fried glutinous rice into the bottle, seal it and put it in a cool place

2、 Is there a shelf life

Dried Dendrobium also has a shelf life, but compared with fresh Dendrobium, it has a longer shelf life and can usually be stored for several years. During storage, it is necessary to ensure good ventilation. It is recommended to put it in a cool and ventilated place. If there is no ventilation during storage, mildew may occur
