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 ...

Abstract

The invention provides a dendrobium leaf-containing composition with a postprandial blood sugar reducing function. The dendrobium leaf-containing composition is prepared from the following raw materials in parts by weight: 1 to 3 parts of freeze-dried powder of a dendrobium leaf hydrolysate, 1 to 3 parts of freeze-dried powder of hericium erinaceus hydrolysate, 1 to 3 parts of freeze-dried powderof plumula nelumbinis, 1 to 3 parts of freeze-dried powder of fructus crataegi and 1 to 3 parts of a sweet and sour taste regulator. The invention also provides a preparation method of the dendrobiumleaf-containing composition. The preparation method comprises the following steps: carrying out hydrolysis and freeze drying on cellulase and pectinase of the dendrobium leaves; carrying out the hydrolysis and the freeze drying on the cellulase of hericium erinaceus; carrying out the freeze drying on the plumula nelumbinis and the fructus crataegi; mixing all the materials in proportions, thus preparing the dendrobium leaf-containing composition. A product prepared by the invention is capable of effectively reducing the postprandial blood sugar, all the materials are medicinal and edible materials, and the product can be taken for a long term, is safe and has a good taste. Meanwhile, a utilization range of the dendrobium leaves is broadened, other parts besides stems are fully developed and utilized, and the utilization rate of a dendrobium plant is increased.

Description

technical field [0001] The invention belongs to the field of food and relates to a health food, in particular to a composition containing dendrobium leaves which has the effect of lowering postprandial blood sugar and a preparation method thereof. Background technique [0002] With the approach of aging society, chronic diseases become the main diseases. Postprandial hyperglycemia is an independent risk factor for macrovascular disease. Postprandial hyperglycemia is associated with increased risk of retinopathy, increased carotid intima-media thickness, decreased myocardial blood volume and blood flow, increased cancer risk, and impaired cognitive function in older adults, as well as oxidative stress, inflammation, and endothelial disfunction. Epidemiological research results show that: lowering postprandial blood sugar can effectively reduce the occurrence of sudden cardiac death. [0003] There are many ways to control blood sugar: low-sugar diet is beneficial to contro...
