Embodiment 1
[0036] The invention provides a composition containing dendrobium leaves with the effect of lowering postprandial blood sugar, which is prepared from the following raw materials in parts by weight:
[0037]
[0038] Further, its dosage form can be powder, granule, pill, tablet, tincture or water.
[0039] Further, the taste-adjusting substance of sugar and acid is composed of sweetener and sour agent, the mass ratio of sweetener and sour agent is 50-800:1, and the sweetener is sorbitol, protein sugar Any one or a combination of two; the sour agent is any one or a combination of citric acid or malic acid.
[0040] The present invention also provides a preparation method of the above-mentioned composition containing dendrobium leaves that has the effect of lowering postprandial blood sugar, comprising the following steps:
[0041] 1) A step for preparing dendrobium leaf hydrolyzate and freeze-dried powder. After sorting, cleaning and drying fresh dendrobium leaves, add water...
Embodiment 2
[0047] 1, Dendrobium leaf pretreatment and cellulase enzymatic hydrolysis process
[0048] Dendrobium leaf sorting→cutting→weighing→adding water→beating→enzymatic hydrolysis→filtering→testing
[0049] Process Description:
[0050] (1) Selection of raw materials: take fresh dendrobium leaves without moth-eaten damaged parts.
[0051] (2) Divide into small pieces: fresh dendrobium leaves are divided into small pieces with a knife, and put into a blender for convenient pulverization.
[0052] (3) Weighing: put the fresh dendrobium leaves in a designated container, and weigh them with an electronic balance.
[0053] (4) Add water: mix it with fresh dendrobium leaves at a material-water ratio of 1g:10ml.
[0054] (5) Pulverization: put fresh Dendrobium leaves into a blender, whip quickly, stop once every 10 seconds, and whip 3-4 times.
[0055] (6) Enzymatic hydrolysis: five groups of factors including enzymatic hydrolysis temperature, enzymatic hydrolysis pH, enzyme amount, an...
Embodiment 3
[0063] 3. Determination of postprandial blood glucose in animals and the hypoglycemic effect of dendrobium leaves
[0064] 3.1 Blood glucose measurement method:
[0065] (1) Orally ingest capsules containing quantitative materials, and then use a blood collection pen to collect blood through the ears of male rabbits every 15 minutes;
[0066] (2) Insert the blood glucose test strip into the matching blood glucose meter, wait for a few seconds, and the blood glucose meter starts up;
[0067] (3) Touch the blood sample to the blood inlet port of the blood glucose test strip, and the blood drop will be sucked automatically;
[0068] (4) Confirm that the amount of blood collected is sufficient;
[0069] (5) Wait for 8 seconds, and the screen will display the blood glucose test result.
[0070] 3.2 Determination procedure for the effect of food on postprandial blood sugar:
[0071] (1) Oral ingestion of capsules containing quantitative white granulated sugar, and blood glucose ...
