example 1

[0016] Example 1: Seabuckthorn seed dregs after degreasing with supercritical carbon dioxide are used as raw materials, pulverized to 40-60 mesh by a pulverizer for subsequent use; the sea buckthorn seed dregs powder is mixed with water at a ratio of 1:5, and the temperature is controlled at 40-50°C. pH 5.5 or so, add 0.5% (w / w)-1.0% (w / w) neutral protease to the feed liquid, heat and stir for 2 hours, filter, wash the filter residue with deionized water to remove the contained protein; then After heating at 100°C for 30 minutes to inactivate the enzyme, cool to 20-30°C, then add 0.5% (w / w) to 1.0% (w / w) cellulase, control the temperature at 45-55°C, and pH 4. 5 to 5.5, after 2 hours of stirring for enzymolysis, the enzymolysis solution is vacuum concentrated, spray-dried, and ultrafinely pulverized to a powder of 10-20 microns to obtain seabuckthorn seed dregs dietary fiber powder.

example 2

[0017] Example 2: using seabuckthorn seed dregs degreased by supercritical carbon dioxide as raw material, pulverized to 60-80 mesh by a pulverizer for subsequent use; mixing said sea buckthorn seed dregs powder with water 1:10, controlling the temperature to 50-60°C, pH 6.0 or so, add 1.0% (w / w)-2.0% (w / w) neutral protease to the feed liquid, heat and stir for 2 hours, filter, and wash the filter residue with deionized water to remove the contained protein; then After heating at 100°C for 30 minutes to inactivate the enzyme, cool to 20-30°C, then add 1.0% (w / w) to 1.5% (w / w) of cellulase, control the temperature at 55-65°C, and pH 5. 5 to 6.5, after 2 hours of stirring for enzymolysis, the enzymolysis solution is vacuum concentrated, spray-dried, and ultrafinely pulverized to a powder of 10-20 microns to obtain seabuckthorn seed dregs dietary fiber powder.

example 3

[0018] Example 3: using seabuckthorn seed dregs degreased by supercritical carbon dioxide as raw material, pulverized to 80-100 mesh by a pulverizer for subsequent use; mixing said sea buckthorn seed dregs powder with water at 1:15, controlling the temperature to 60-70°C, pH 6.5 or so, add 2.0% (w / w)-3.0% (w / w) neutral protease to the feed solution, heat and stir for 2 hours, filter, and wash the filter residue with deionized water to remove the contained protein; then After heating at 100°C for 30 minutes to inactivate the enzyme, cool to 20-30°C, then add 1.5% (w / w) to 2.0% (w / w) of cellulase, control the temperature at 65-75°C, and pH6. 5 to 7.5, after 2 hours of stirring for enzymolysis, the enzymolysis solution is vacuum concentrated, spray-dried, and ultrafinely pulverized to a powder of 10-20 microns to obtain seabuckthorn seed dregs dietary fiber powder.

Abstract

The invention relates to a preparation method of an edible sea-buckthorn dietary fiber. The method comprises the following steps of: mixing sea-buckthorn seed residual after supercritical carbon dioxide degreasing treatment with water, adding a neutral protease into the resulting product, preserving heat and stirring for 2 hours, filtering the resulting product, washing the filter residue with deionized water, deactivating enzyme, cooling the resulting product, adding cellulase into the cooled product, stirring for 2 hours so as to carry out enzymolysis, carrying out vacuum concentration on enzymatic hydrolysate, carrying out spray-drying on the resulting product, and ultra-finely crushing the resulting product to obtain the sea-buckthorn seed dietary fiber powder. The edible sea-buckthorn dietary fiber prepared by the method provided by the invention is fine in particles, the total dietary fiber content reaches more than 80%, wherein the soluble dietary fiber content reaches more than 30%, and the edible sea-buckthorn dietary fiber can be applied to the fields of various beverages, foods and healthcare foods.

Description

technical field [0001] The invention relates to a method for preparing dietary fiber, in particular to a method for preparing edible seabuckthorn dietary fiber from seabuckthorn seed dregs. Background technique [0002] With the rapid development of my country's economy, people's daily diet structure has undergone great changes. However, due to unscientific dietary structure and insufficient intake of dietary fiber, the emergence of "civilization disease", high blood pressure, hyperlipidemia, diabetes, constipation, obesity, coronary heart disease, etc. are all related to insufficient intake of high-quality dietary fiber , has brought serious harm to people's health. Patients with coronary heart disease, hypertension, and diabetes account for more than 15% of adults in cities across the country, and they are increasing year by year. Dietary fiber is a very important component to maintain the normal functioning of the human body. After in-depth research, nutritionists have ...
