Embodiment 1

[0034] 1) Processing of apple pomace

[0035] Add 4 times the volume of 40°C distilled water into the apple pomace, stir at room temperature for 30 minutes, then filter, collect the filter residue, wash the filter residue twice with 40°C distilled water, dry it in a 60°C blast drying oven, and then crush it. Pass through a 40-mesh sieve to obtain the apple pomace raw material.

[0036] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0037] Mix apple pomace raw material and acetate buffer solution with a pH of 5.2 at a material-to-liquid ratio of 1:20 (g:mL), add pectinase at a ratio of 100 U / g apple pomace raw material, and shake in a shaker at 40°C, Incubate at 100r / min for 12h. After enzymatic hydrolysis, directly add 4 times the volume of 95% ethanol, let it stand at room temperature for 2 hours, filter it with suction, put the filter residue in an oven at 60°C until it is dried until the water content of the solid does not exceed 8%, and then the apple pomac...

[0047] 1) Processing of apple pomace

[0048] Add 4 times the volume of 30°C distilled water into the apple pomace, stir at room temperature for 30 minutes, then filter, collect the filter residue, wash the filter residue twice with 30°C distilled water, dry it in a 60°C blast drying oven, and then crush it. Pass through a 40-mesh sieve to obtain the apple pomace raw material.

[0049] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0050] Mix apple pomace raw material and acetate buffer solution with a pH of 4.4 at a material-to-liquid ratio of 1:20 (g:mL), add pectinase at a ratio of 200 U / g of apple pomace raw material, and shake in a shaker at 37°C, Incubate at 150r / min for 18h. After enzymatic hydrolysis, directly add 4 times the volume of 95% ethanol, let it stand at room temperature for 2 hours, filter it with suction, put the filter residue in an oven at 60°C until it is dried until the water content of the solid does not exceed 8%, and then the apple po...

Embodiment 3

[0060] 1) Processing of apple pomace

[0061] Add 4 times the volume of 50°C distilled water into the apple pomace, stir at room temperature for 30 minutes, then filter, collect the filter residue, wash the filter residue twice with 50°C distilled water, dry it in a 60°C blast drying oven, and then crush it. Pass through a 40-mesh sieve to obtain the apple pomace raw material.

[0062] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0063] Mix apple pomace raw material and acetate buffer solution with a pH of 3.6 at a material-to-liquid ratio of 1:15 (g:mL), add cellulase at a ratio of 250 U / g apple pomace raw material, and shake in a shaker at 35°C, Incubate at 100r / min for 24h. After enzymatic hydrolysis, directly add 4 times the volume of 95% ethanol, let it stand at room temperature for 2 hours, filter it with suction, put the filter residue in an oven at 60°C until it is dried until the water content of the solid does not exceed 8%, and then the apple pomac...

Abstract

The invention discloses a natural dietary fiber supplement with a hypoglycemic effect and a preparation method thereof. The natural dietary fiber supplement is prepared from, by weight, 20-50 parts ofan apple pomace extract, 20-80 parts of a blueberry pomace extract and 5-30 parts of dehydrated nettle leaves. According to the preparation method, with apple pomace, blueberry pomace and nettle leaves as raw materials, soluble dietary fibers in the apple pomace and blueberry pomace extracts are utilized, the hypoglycemic effect of anthocyanin components and components in the nettle leaves is improved, and therefore the dietary fiber supplement with natural component composition and the hypoglycemic effect is obtained. According to the natural dietary fiber supplement with the hypoglycemic effect and the preparation method thereof, the adopted pomace raw materials are by-products of processing products of apples and blueberries; the high-added-value utilization of the apples and blueberries is achieved by effectively extracting the rich dietary fibers in the apple pomace and blueberry pomace, and good economical benefits can be obtained.

Description

technical field [0001] The invention relates to the technical field of dietary health products, in particular to a natural dietary fiber supplement with hypoglycemic effect and a preparation method thereof. Background technique [0002] As a metabolic disease, diabetes is mainly characterized by insufficient insulin secretion by the islets of the pancreas, which leads to the inability to fully decompose and absorb the sugar ingested by the body, resulting in a long-term high level of blood sugar in the body, which is harmful to the eyes, kidneys, and heart. , blood vessels, nerves and other tissues and organs cause chronic damage and destruction. The occurrence of the imbalance of glucose and lipid metabolism in the human body is closely related to the imbalance of dietary structure, the most critical of which is the lack of dietary fiber intake. Dietary fiber refers to a class of non-starch polysaccharides that are not digested and absorbed by digestive enzymes in the inte...
