Embodiment 1

[0032] (1) Material pretreatment: Dry the fresh strips of Dendrobium at 80°C for 5 hours to obtain dry strips of Dendrobium with a moisture content of 5.2%, then grind the dried strips of Dendrobium, and sieve to select Dendrobium powder with a particle size of less than 200 mesh A;

[0033] (2) Shearing and stirring treatment: add 5 g of the dendrobium powder A obtained in step (1) into 1000 g of water, shear and stir at 40° C. for 1 hour, fully swell the fibers, and obtain the initial extract B and wet residue C after filtration;

[0034] (3) freeze-drying treatment: the wet residue C obtained in step (2) was freeze-dried for 24 hours at -30° C. to obtain dry powder D. Freeze-drying treatment can improve the wall-breaking rate of dendrobium fibers and remove free water and Combining water to form a loose and porous structure is more conducive to subsequent processing;

[0035] (4) Enzymolysis treatment: add cellulase, hemicellulase and pectinase to the dry powder D obtained...

Embodiment 2

[0045] (1) Material pretreatment: Dry the fresh strips of Dendrobium at 90°C for 6 hours to obtain dry strips of Dendrobium with a moisture content of 4.8%, then grind the dried strips of Dendrobium, and sieve to select Dendrobium powder with a particle size of less than 250 mesh A;

[0046] (2) Shear stirring treatment: add 10 g of the dendrobium powder A obtained in step (1) into 1000 g of water, shear and stir at 50° C. for 2 hours, fully swell the fibers, and obtain the initial extract B and wet residue C after filtration;

[0047] (3) Freeze-drying treatment: the wet residue C obtained in step (2) was freeze-dried for 48 hours at -40° C. to obtain dry powder D. Freeze-drying treatment can improve the wall-breaking rate of dendrobium fibers and remove free water and Combining water to form a loose and porous structure is more conducive to subsequent processing;

[0048] (4) Enzymolysis treatment: add cellulase, hemicellulase and pectinase to the dry powder D obtained in ste...

Embodiment 3

[0058] (1) Material pretreatment: Dry the fresh dendrobium strips at 100°C for 8 hours to obtain dry dendrobium strips with a moisture content of 3.7%, then grind the dry strips of dendrobium into powder, and sieve to select dendrobium powder with a particle size of less than 300 mesh A;

[0059] (2) Shearing and stirring treatment: add 30 g of dendrobium powder A obtained in step (1) into 1000 g of water, shear and stir at 60° C. for 3 hours, fully swell the fibers, and obtain initial extract B and wet residue C after filtration;

[0060] (3) freeze-drying treatment: the wet residue C obtained in step (2) was freeze-dried for 108 hours at -50° C. to obtain dry powder D. Freeze-drying treatment can improve the wall-breaking rate of dendrobium fibers and remove free water and Combining water to form a loose and porous structure is more conducive to subsequent processing;

[0061] (4) Enzymolysis treatment: add cellulase, hemicellulase and pectinase to the dry powder D obtained...

Abstract

The invention relates to dendrobium officinale powder preparation method which is characterized by including the steps: (1) material pretreatment; (2) cutting and stirring; (3) freeze-drying; (4) enzymatic hydrolysis; (5) high-pressure homogenizing; (6) fermentation; (7) vacuum concentration; (8) spray-drying. Compared with the prior art, the method has the advantages that the enzymatic hydrolysisis matched with fermentation to generate biochemical doubling effect, preliminary enzymolysis of dendrobium officinale fibers can be achieved by enzymatic hydrolysis treatment, cellulose and hemicellulose in the dendrobium officinale can be converted into fermentable glycogen, nutrients are provided for metabolic acid production of follow-up lactobacillus and acetic bacteria, cellulose is hydrolyzed under acid condition, fibers are further hydrolyzed by enzymes generated after bacillus metabolizes, a firm ester bond formed between lignin and cellulose is destroyed, the prepared dendrobium officinale powder is high in dendrobium officinale fiber content and good in dispersibility, and the utilization rate of dendrobium officinale raw materials is high.

Description

technical field [0001] The invention relates to the technical field of plant powder processing, in particular to a preparation method of dendrobium officinale powder. Background technique [0002] Dendrobium was first recorded in "Shen Nong's Materia Medica", and the Dendrobium included in the Chinese Pharmacopoeia includes Dendrobium nobile, Dendrobium drumstick, Dendrobium fringe, and Dendrobium candidum. Dendrobium has the effects of nourishing the stomach and promoting body fluid, nourishing yin and clearing away heat. For febrile disease fluid injury, dry mouth and polydipsia, insufficient stomach yin, lack of food and retching, persistent asthenic fever after illness, hyperactivity of fire due to yin deficiency, bone steaming and labor-heat, blurred vision, muscle flaccidity and weakness. Dendrobium is known as "Chinese Immortal Grass" among the people, and it is the only source of famous and precious Chinese herbal medicine Fengdou. According to the difference in wat...
