Embodiment 1

[0030] 1) Processing of apple pomace

[0031] Add 4 times the volume of 40 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, put it into a 60°C blast drying oven, dry it, and then crush it. A 40-mesh sieve obtained the apple pomace raw material.

[0032] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0033] Mix apple pomace raw material and acetate buffer solution with a pH of 5.2 at a solid-liquid ratio of 1:15 (g:mL), add pectinase at a ratio of 100 U / g of 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 pomace extrac...

Embodiment 2

[0041] 1) Processing of apple pomace

[0042] Add 4 times the volume of distilled water at 25°C to the apple pomace, stir at room temperature for 30 minutes, then filter, collect the filter residue, wash the filter residue twice with 25°C distilled water, dry it in a blast drying oven at 60°C, and then crush it. Pass through a 40-mesh sieve to obtain the apple pomace raw material.

[0043] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0044] Mix apple pomace raw material and acetate buffer solution with a pH of 3.6 at a material-to-liquid ratio of 1:20 (g:mL), add cellulase according to the ratio of 200U / g 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 th...

Embodiment 3

[0052] 1) Processing of apple pomace

[0053] 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.

[0054] 2) Enzymatic hydrolysis and post-treatment of apple pomace

[0055] 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 cellulase according to the ratio of 250U / 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 ...

Abstract

The invention discloses a natural dietary fiber supplement with a lipid lowering effect and a preparation method thereof. The natural dietary fiber supplement is prepared from, by weight, 20-80 partsof an apple pomace extract and 20-80 parts of a blueberry pomace extract. According to the preparation method, with apple pomace and blueberry pomace as raw materials, on the basis of keeping the activity of blueberry anthocyanin, the content of soluble dietary fibers in the apple pomace and blueberry pomace extracts is increased, and therefore the dietary fiber supplement with natural component composition and the lipid lowering effect is obtained. According to the natural dietary fiber supplement with the lipid lowering effect and the preparation method thereof, the high-added-value utilization of apples and blueberries is achieved by effectively extracting the 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 lipid-lowering effect and a preparation method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's dietary structure has undergone major changes, mainly characterized by high calorie and low fiber intake, of which dietary fiber intake is about the normal adult diet recommended by the Chinese Nutrition Society 50% of fiber intake (25-30g / d). The incidence of obesity, hyperlipidemia, and lipid metabolism disorders caused by this eating habit shows a clear upward trend. Dietary fiber refers to a class of non-starch polysaccharides that are not digested and absorbed by digestive enzymes in the intestine, but can be partially fermented and utilized by certain microorganisms in the large intestine. It mainly comes from the cell wall of plants, in...
