Embodiment 1

[0036] Drying of dendrobium flowers:

[0037] (1) Picking: pick within 48 hours after the dendrobium blooms, and cut from the base of the inflorescence stalk;

[0038] (2) selection: the plucked dendrobium flowers are selected to remove rotten flowers and impurities;

[0039] (3) Cleaning: Rinse with clean water for 3 times, dissolve sodium gluconate into the clean water during the first rinse with clean water, dissolve 1g of sodium gluconate per liter of clean water, and replace with clean clean water after the first two rinses;

[0040] (4) Color protection: soak the cleaned Dendrobium flowers in the color protection solution for 10 minutes, pick up, and drain the water; the color protection solution is made by dissolving L-calcium ascorbate in water, the mass ratio of L-calcium ascorbate to water is 5:95;

[0041] (5) Drying: Dry the dendrobium flowers at 55°C for 10 minutes after color protection, then dry at 80°C for 5 minutes, and finally dry at 105°C to constant weigh...

Embodiment 2

[0044] Taking Example 1 as a comparison, set up Example 2 in which the color protection solution is made by dissolving L-calcium ascorbate and food-grade polyglutamic acid in water, and the rest of the operations are exactly the same.

[0045] Drying of dendrobium flowers:

[0046] (1) Picking: pick within 48 hours after the dendrobium blooms, and cut from the base of the inflorescence stalk;

[0047] (2) selection: the plucked dendrobium flowers are selected to remove rotten flowers and impurities;

[0048] (3) Cleaning: Rinse with clean water for 3 times, dissolve sodium gluconate into the clean water during the first rinse with clean water, dissolve 1g of sodium gluconate per liter of clean water, and replace with clean clean water after the first two rinses;

[0049] (4) Color protection: Soak the cleaned Dendrobium flowers in the color protection solution for 10 minutes, pick up, and drain the water; the color protection solution is made by dissolving L-calcium ascorbate...

Embodiment 3

[0053] Taking Example 1 as a comparison, set Example 3 in which sodium gluconate is replaced by an equal amount of polylysine-gallic acid, and the rest of the operations are identical.

[0054] Drying of dendrobium flowers:

[0055] (1) Picking: pick within 48 hours after the dendrobium blooms, and cut from the base of the inflorescence stalk;

[0056] (2) selection: the plucked dendrobium flowers are selected to remove rotten flowers and impurities;

[0057] (3) Cleaning: Rinse with clean water for 3 times, dissolve polylysine-gallic acid in the clean water during the first rinse, dissolve 1g of polylysine-gallic acid per liter of clean water, and rinse for the first two times Clean water needs to be replaced after the end;

[0058] (4) Color protection: soak the cleaned Dendrobium flowers in the color protection solution for 10 minutes, pick up, and drain the water; the color protection solution is made by dissolving L-calcium ascorbate in water, the mass ratio of L-calciu...

Abstract

The invention discloses a drying technology of dendrobium nobile flowers, and relates to the technical field of dendrobium nobile flower processing. The drying technology comprises the following stepsof 1, picking, 2, selecting, 3, cleaning, 4, color protection, 5, drying and 6, storage. According to the drying technology, the color and luster of the dendrobium nobile flowers are preserved through the color protection working procedure, and the problem of color changing of the dendrobium nobile flowers during high-temperature drying is solved; meanwhile, the problem that the dendrobium nobileflowers are in contact with air and change color in the storage process is also solved; meanwhile, in the cleaning working procedure, sodium gluconate is added to increase the impurity removal rate of the dendrobium nobile flowers.

Description

[0001] Technical field: [0002] The invention relates to the technical field of dendrobium flower processing, in particular to a drying process for dendrobium flowers. [0003] Background technique: [0004] Dendrobium, the flower of Dendrobium, has very high medicinal value. It can nourish yin and lungs, nourish the stomach and promote body fluid, improve eyesight and clear away heat. It has the effect of enhancing immunity and anti-aging. It is effective for respiratory diseases, diabetes, Chronic hepatitis, chronic gastritis, etc. are beneficial. And the Dendrobium flower contains a variety of volatile oils, which are volatile, can make people feel cheerful, and can relieve symptoms such as high mental stress, easy fatigue, irritability, and depression. [0005] If the picked Dendrobium flowers are not dried, they will soon rot and lose their medicinal value. In order to realize the high-value utilization of Dendrobium flowers, it is necessary to dry the freshly picked De...
