Problems solved by technology

[0004] Because fresh Dendrobium candidum is not suitable for preservation, fresh raw materials are easy to rot and deteriorate due to their juiciness and tenderness, especially in mildewy rainy seasons, it is even more difficult to preserve, and although the preservation time can be prolonged after drying, the sensory indicators will deteriorate. Physiologically active ingredients are also affected, resulting in a decrease in their efficacy

Embodiment 1

[0027] A processing method of dendrobium officinale, comprising the following steps:

[0028] Step 1. Collect the Dendrobium officinale with strong plants and no pests, remove the fibrous roots and leaves, and wash it for later use; soak the cleaned Dendrobium officinale in a 4% potassium permanganate solution for 3 minutes, and then rinse the Dendrobium officinale with water. Drain again;

[0029] Step 2, placing the Dendrobium candidum drained in step 1 in a freeze dryer for freezing, and the Dendrobium candidum dropped from 25°C to -30°C in 1.5h;

[0030] Step 3. Dry the Dendrobium candidum after the quick freezing in step 2 under a vacuum degree of 20-40pa, and dry for the first time for 1h, and gradually increase the temperature from -30°C to -20°C; when the temperature rises to -20°C, carry out For the second drying, the drying time is 2 hours, and the temperature is gradually increased from -20°C to -10°C; when the temperature rises to -10°C, the third drying is carrie...

Abstract

The invention belongs to the technical field of processing of medicinal and edible substances, and particularly relates to a processing method and application of dendrobium officinale. Firstly, dendrobium officinale is collected, fibrous roots and leaves are removed, and dendrobium officinale is washed thoroughly for standby application; dendrobium officinale washed thoroughly is soaked in a potassium permanganate solution, dendrobium officinale is flushed with water, and water is drained off; after thorough draining, dendrobium officinale is placed in a freezing drying machine for quick freezing, dendrobium officinale is cooled to -30--40 DEG C from the normal temperature of 25-30 DEG C, and dendrobium officinale is gradually heated for vacuum drying. Before freezing of dendrobium officinale, the potassium permanganate solution is adopted for sterilizing, temperature changes in the quick freezing, gradual temperature rising and vacuum drying processes retain the physiological functions of dendrobium officinale under the premise of not damaging the nutritive value, and dendrobium officinale can be used for making dendrobium officinale cakes and dendrobium officinale grain powder, brewing for drinking and making dendrobium officinale preserved fruit. Dendrobium officinale processed by adopting the method cam be kept for three years.

Description

technical field [0001] The invention belongs to the technical field of processing food and drug homologous substances, and in particular relates to a processing method and application of dendrobium officinale. Background technique [0002] Dendrobium officinale is a rare food and medicine homologous substance. It is a perennial herb with clustered stems, cylindrical shape, 10-30 cm high and 3-8 mm thick. It is known as "life-saving fairy grass" among the people. "Giant Panda". [0003] Dendrobium candidum has high edible and medicinal value. Modern medical research shows that Dendrobium candidum has multiple functions such as nourishing the stomach and promoting body fluid, enhancing immunity, anti-aging, anti-tumor and lowering blood sugar. The 2010 edition of "The Pharmacopoeia of the People's Republic of China" records that Dendrobium officinale can be used for stomach yin deficiency, bone steaming, labor heat and other effects. [0004] Because fresh Dendrobium candidu...
