Background
Iron sheet stone (Dendrobium officinale) is the most famous and precious one of the Dendrobium medicinal materials with the highest medicinal value. Its polysaccharide content is up to 20% -30%, crude fibre content is above 10%, and it contains 18 amino acids and several trace elements. Modern medical experiments prove that the dendrobium officinale has various efficacies of resisting tumor, diminishing inflammation, reducing blood pressure, reducing blood sugar, nourishing yin, moistening dryness, strengthening spleen, stimulating appetite and the like, and is beneficial to the health and the longevity of human bodies. With the promotion of the market acceptance degree of dendrobium, even if the purchase price of fresh dendrobium officinale medicinal materials can reach thousands yuan per kilogram, the market demand is still gradually enlarged and is in an unsaturated state. The dendrobium officinale is mainly processed into dendrobium officinale buckets to be sold, a small amount of dendrobium officinale buckets are used for deep processing of solid beverages, nutrient substances in the dendrobium officinale buckets are difficult to completely utilize when the dendrobium officinale buckets are used for processing the beverages, and waste is easily caused.
Chinese patent publication No. CN 108606226A discloses a dendrobium solid beverage and a preparation method thereof, which introduces a plurality of active substances and biological enzymes to increase flavor, taste and efficacy, but prepares the filtered dendrobium fermentation liquid into dendrobium ferment freeze-dried powder as a core raw material, and reduces the range of abundant nutrients in fresh dendrobium officinale from the source and depreciates.
Chinese patent publication No. CN 107467466A discloses a method for preparing an instant solid beverage of dendrobium officinale, which comprises vacuum drying the supernatant of the juice to obtain instant solid powder.
