Description

Technical Field

[0001] The invention relates to the technical field of deep processing of Chinese medicinal materials, in particular to a Huoshan Taiping Dendrobium officinale fresh stem puree freeze-dried powder and a preparation method thereof. The invention obtains a dendrobium product with high absorption rate and convenient to carry and use by performing special processing on the Huoshan Dendrobium officinale (Dendrobium officinale) fresh strips, thereby solving the problems of nutrient loss, low absorption efficiency, and inconvenience in carrying of existing dendrobium products during processing and use. Background Art

[0002] Huoshan Dendrobium (Dendrobium huoshanense), also known as Mihu, is one of the traditional precious Chinese medicinal materials, known as the "first of the nine immortal herbs in China". It mainly grows in Huoshan County, Anhui Province and surrounding areas. Due to its unique medicinal value and nourishing effect, it is widely used to improve human immunity, anti-fatigue, anti-aging, etc.

[0003] The existing processing methods of dendrobium products mainly include drying fresh dendrobium strips and processing them into maple pods, dried strips, a series of beverages, etc. During the production process of these products, due to processes such as high-temperature drying, some nutrients will be lost. At the same time, when consumers use these products, they usually need to soak, boil water or stew soup. If the time and method are not appropriate, the nutrients of dendrobium are often not fully absorbed, resulting in nutritional waste. In addition, these products also have many inconveniences in use and carrying, such as requiring cumbersome cooking steps and being difficult to carry.

[0004] In order to solve the above problems, the present invention proposes a new Huoshan Taiping Dendrobium officinale fresh stem puree freeze-dried powder and a preparation method thereof, aiming to improve the nutritional absorption rate, ease of use and portability of Dendrobium officinale products. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a freeze-dried powder of Huoshan Taiping Dendrobium officinale fresh stem puree and a preparation method thereof, which can better retain and absorb the nutrients in the Dendrobium officinale through special process treatment, while improving the convenience and portability of the product.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0007] (1) Raw material selection:

[0008] Select high-quality Huoshan Dendrobium (Mihu) fresh strips grown on stones for more than five years;

[0009] The raw materials must be strictly screened to ensure they are free of pests and diseases, mechanical damage, and have consistent maturity;

[0010] (2) Fresh strip processing:

[0011] Wash the selected fresh strips to remove surface dirt and impurities;

[0012] Use special equipment to puree the fresh strips to ensure that the cell walls are broken to release more nutrients;

[0013] (3) Freezing treatment:

[0014] The puree is quickly frozen to -70 degrees Celsius and kept for no less than 72 hours;

[0015] (4) Breaking the cell wall into powder:

[0016] The frozen puree is taken out and processed into powder using secondary wall breaking technology. During the wall breaking process, the powder particle size must reach 1200 mesh;

[0017] (5) Freeze-drying:

[0018] The powder after the cell wall is vacuum freeze-dried to remove moisture and obtain freeze-dried powder. The freeze-drying process needs to be carried out at low temperature and low pressure to retain the nutrients and active substances in the powder;

[0019] (6) Packaging and storage:

[0020] Aseptically package the freeze-dried powder to ensure product hygiene and quality;

[0021] Store in a cool, dry place, avoid direct sunlight and high temperatures.

[0022] Beneficial effects of the present invention:

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) Improve the absorption rate of nutrients: By breaking the wall, the powder particle size must reach 1200 mesh, and freezing to minus 70 degrees, the nutrients in the dendrobium can be fully released and preserved, thereby improving the absorption rate of the product.

[0025] (2) Easy to use: Freeze-dried powder can be eaten directly or dissolved in water for drinking. It does not require complicated cooking steps and is convenient and quick.

[0026] (3) Easy to carry: Freeze-dried powder is small in size and light in weight, making it easy to carry and store.

[0027] (4) Technological innovation: The present invention is the first of its kind in the reprocessing and production technology of Dendrobium series products, filling a gap in the market. DETAILED DESCRIPTION
