Embodiment 1

[0071] (1) Chop the yew branches, dry, crush, and pass through a 80-mesh sieve. The sieve is ready for use.

[0072] (2) Weigh 10 kg of the undersize, put it in a reflux extraction tank, add 2 times by mass of No. 6 solvent oil, and reflux for 2 hours to degrease.

[0073] (3) Suction filtration, recover No. 6 solvent oil, air-dry the filter residue, and set aside.

[0074] (4) Take the filter residue, place it in a heating and stirring tank, add 10 times the mass of water, stir and soak at a low speed at 50°C for 30 minutes. Make the yew powder residue fully absorb water to form a slurry.

[0075] (5) Pour the slurry prepared in (4) into the colloid mill in batches, and grind for 5 minutes in a circular manner. Grind the slurry to a homogenate.

[0076] (6) Pour the slurry prepared in (5) into a high-pressure homogenizer, perform high-pressure shear homogenization, twice, and the pressure is 800 bar.

[0077] (7) Put the homogenized slurry into a stirring tank, add 0.5% ...

Embodiment 2

[0082] (1) Chop the yew branches, dry, crush, and pass through a 80-mesh sieve. The sieve is ready for use.

[0084] (3) Suction filtration, recover No. 6 solvent oil, air-dry the filter residue, and set aside.

[0085] (4) Take the filter residue, place it in a heating and stirring tank, add 5 times the mass of water, stir and soak at a low speed at 70°C for 30 minutes. Make the yew powder residue fully absorb water to form a slurry.

[0086] (5) Pour the slurry prepared in (4) into the colloid mill in batches, and grind for 5 minutes in a circular manner. Grind the slurry to a homogenate.

[0087] (6) Pour the slurry prepared in (5) into a high-pressure homogenizer, perform high-pressure shear homogenization, twice, and the pressure is 1600 bar.

[0088] (7) Put the homogenized slurry into a stirring tank, add 1...

Embodiment 3

[0095] (1) Chop the yew branches, dry, and crush through an 80-mesh sieve. The sieve is ready for use.

[0096] (2) Weigh 10 kg of the undersize, put it in a reflux extraction tank, add 2 times by mass of No. 6 solvent oil, and reflux for 2 hours to degrease.

[0097] (3) Suction filtration, recover No. 6 solvent oil, air-dry the filter residue, and set aside.

[0098] (4) Take the filter residue, put it in a heating and stirring tank, add 10 times the mass of water, stir and soak at a low speed at 50°C for 30 minutes. Make the yew powder residue fully absorb water to form a slurry.

[0099](5) Pour the slurry prepared in (4) into the colloid mill in batches, and grind for 5 minutes in a circular manner.

[0100] (6) Pour the slurry prepared in (5) into a high-pressure homogenizer, perform high-pressure shearing and homogenization twice, and the pressure is 800 bar.

[0101] (7) Put the homogenized slurry into a stirring tank, add 0.5% cellulase of the quality of the air-d...

Abstract

The invention relates to a method for extracting dietary fiber from Chinese yew. The method disclosed by the invention adopts a high pressure homogenization-enzyme combination method. According to the extraction method of the dietary fiber, disclosed by the invention, the yield of the soluble dietary fiber can be improved, the production process is simple and easy to operate, and chemical residues can be avoided.

Description

technical field [0001] The invention relates to a dietary fiber, an extraction method and its use, in particular to a dietary fiber extracted from yew, an extraction method and its use. Background technique [0002] In 1976, H.C. Trowell, a British nutritional expert, defined "polysaccharide carbohydrates and lignin that are not digested and absorbed by the human body" as "dietary fiber". Dietary fiber is called "the seventh largest nutrient" in modern nutrition. Dietary fiber has physiological functions such as preventing obesity, preventing and treating diabetes, regulating blood lipid levels, preventing colon cancer, inhibiting toxic fermentation products, preventing intestinal diverticulum and breast cancer. Acidic polysaccharides in dietary fiber have strong cation exchange capacity, and can interact with Na in the intestine + 、K + Exchange, affect the pH value, osmotic pressure and oxidation potential of the digestive tract, so that the Na in the blood + 、K + Rati...
