Example Embodiment

[0023] Example 1

[0024] Mix 1000g oat bran with 12 times the weight of oat bran in water, heat to 90°C for 1 hour, filter to remove precipitation, cool to 55°C, add 0.8% oat bran weight to hydrolyze with neutral cellulase for 1 hour, and heat up Incubate at 95°C for 10 minutes to inactivate the enzyme, cool to room temperature and remove the supernatant by filtration, and spray-dry to obtain oat extract No. 1.

[0025] The test results showed that the oat β-glucan content in oat extract No. 1 was 30.1%, the protein content was 24.2%, and the fat content was 3.5%.

[0026] Control sample:

[0027] Mix 1kg of oat bran with water of 12 times the weight of oat bran, heat to 90°C for 1 hour, filter to remove precipitates, cool to 55°C, heat up to 95°C for 10 minutes to inactivate the enzyme, and filter to remove the supernatant after cooling to room temperature Liquid, spray-dried to obtain an oat extract control sample.

[0028] The test results showed that the content of oat β-glucan i...

[0033] Example 2

[0034] Mix 10kg of oat bran with 6 times the weight of oat bran in water, heat to 80°C for 2h, filter to remove precipitation, cool to 45°C, add 0.3% oat bran weight to hydrolyze with neutral cellulase for 1h, heat up Incubate at 90°C for 15 minutes to inactivate the enzyme, filter to remove the supernatant after cooling to room temperature, and spray-dry to obtain oat extract No. 2.

[0035] The test results showed that the oat β-glucan content in oat extract No. 2 was 28.4%, the protein content was 22.8%, and the fat content was 2.9%.

[0036] Mix 10kg oat bran with 6 times the weight of oat bran and heat to 80℃ to keep

[0037] Hold for 2 hours, filter to remove the precipitate, after cooling to 45°C, heat up to 90°C for 15min to inactivate the enzyme, filter to remove the supernatant after cooling to room temperature, and spray dry to obtain the control sample No. 2 of oat extract.

[0038] The volunteers consisted of 12 women aged 25-70 years and 10 men aged 30-...

Example Embodiment

[0042] Example 3

[0043] Mix 50kg oat bran with 10 times the weight of oat bran in water, heat to 92°C for 1.5h, filter to remove precipitation, cool to 50°C, add 0.6% of the oat bran weight to hydrolyze with neutral cellulase for 2h, The temperature was raised to 95°C for 10 min to inactivate the enzyme, and the supernatant was filtered off after cooling to room temperature, and the oat extract No. 3 was obtained by spray drying.

[0044] The test results showed that the oat β-glucan content in oat extract No. 3 was 30.4%, the protein content was 24.6%, and the fat content was 3.0%.

[0045] It can be seen that the oat extract prepared by the present invention can be used in the preparation of health care products and medicines for improving constipation.

Abstract

The invention discloses an oat extract with a constipation improving function as well as a preparation method and an application thereof. The preparation method comprises the following concrete steps: mixing oat bran with water 8-12 times the weight of the oat bran, heating to 80-90 DEG C, maintaining the temperature for 1-2 hours, filtering to remove precipitates, cooling to 45-55 DEG C, adding cellulose, hydrolyzing for 1-3 hours, heating to 90-95 DEG C and maintaining the temperature for 10-15 minutes to kill the enzyme, cooling to the room temperature and obtaining the oat extract. The preparation method disclosed by the invention has the advantages that an organic reagent is not needed; the extraction method and the separation method are simple and convenient; and the obtained products are good in biological activity. Proved by human experimentations of volunteers, through the ingestion of 5-10 grams of the oat extract disclosed by the invention before meals, the constipation status can be obviously improved and the regular bowel habit is regained.

Description

technical field [0001] The invention relates to the preparation method and application field of oat products, in particular to an oat extract capable of improving constipation and its preparation method and application. Background technique [0002] Oat (Avenasativa) has important nutritional and health functions such as lowering serum cholesterol, triglyceride and serum low-density lipoprotein cholesterol, and its health function is mainly attributed to the soluble dietary fiber-β-glucan in oat grains. Oat β-glucan (Oatβ-glucan) is a white to light yellow powder made from oat or oat bran through hydrolysis, extraction, precipitation, drying, sterilization and other processes. starch polysaccharides. Oat β-glucan is a structural non-starch polysaccharide existing in the cell wall of oats. It was identified as one of the new resource foods by the Ministry of Health in 2014. Oat β-glucan has many physiological activities such as lowering blood fat, lowering blood pressure, p...
