Problems solved by technology

Banana is a fruit with more respiration, which is not resistant to storage, easy to deteriorate, and the loss after harvest is very serious. At the same time, the processing technology is backward, which is wasteful and pollutes the environment.
[0009] At the same time, there is no report on the clear material basis of banana for treating constipation, and the mechanism of action is still unclear. There is no research report on the combination of banana oligosaccharides and dietary fiber to prepare laxative functional food

Embodiment 1

[0036] Embodiment 1 prepares composition according to the following method

[0037] (1) Peel the bananas; beat the pulp for 2.5 minutes, extract with water, the weight-to-volume ratio of the material to liquid is 1g: 1ml, the temperature is 60°C, the extraction time is 50min, and the extraction is 4 times; the 4 extractions are combined, and the pomace is placed separately , the extract was filtered and concentrated in vacuum, precipitated with 4 times the volume of the extract in absolute ethanol, centrifuged at 3500 rpm for 14 minutes, collected the precipitate, and vacuum freeze-dried at 50Pa to 80Pa for 4 hours to obtain the banana oligosaccharide product;

[0038] (2) The remaining pomace after extraction of banana sugar liquid is used for enzymatic hydrolysis to prepare banana soluble and insoluble dietary fiber:

[0039] Step A: Add amylase to the pomace, the amount of amylase is 3.6% of the pomace weight, the action temperature is 100°C, add calcium chloride to make th...

Embodiment 2

[0044] (1) Peel the bananas; beat the pulp for 3 minutes, extract with water, the weight-to-volume ratio of the material to liquid is 1g: 1ml, the temperature is 50°C, the extraction time is 60min, and the extraction is performed 4 times; After conventional suction filtration and vacuum concentration, the extract was precipitated with 4 times the volume of the extract in absolute ethanol, centrifuged at 4500 rpm for 12 minutes, the precipitate was collected, and vacuum freeze-dried at 60Pa to 100Pa for 5 hours to obtain the banana oligosaccharide product;

[0045] (2) The remaining pomace after extraction of banana sugar liquid is used for enzymatic hydrolysis to prepare banana soluble and insoluble dietary fiber:

[0046] Step A: Add amylase to the pomace, the amount of amylase is 4.0% of the pomace weight, the action temperature is 95°C, add calcium chloride to make the calcium ion concentration 20mmol / L, adjust by adding hydrochloric acid and sodium hydroxide solution The p...

Embodiment 3

[0051] (1) Peel the bananas; beat the pulp for 2 minutes, extract with water, the weight-to-volume ratio of the material to liquid is 1g: 1ml, the temperature is 55°C, the extraction time is 55min, and the extraction is 5 times; the 5 extractions are combined, and the pomace is placed separately. The extract was filtered and concentrated in vacuum, precipitated with 4 times the volume of the extract in absolute ethanol, centrifuged at 4000 rpm for 13 minutes, collected the precipitate, and vacuum freeze-dried at 100Pa to 150Pa for 4 hours to obtain the banana oligosaccharide product;

[0052] (2) The remaining pomace after extraction of banana sugar liquid is used for enzymatic hydrolysis to prepare banana soluble and insoluble dietary fiber:

[0053] Step A: Add amylase to the pomace, the amount of amylase is 3.8% of the pomace weight, the action temperature is 98°C, add calcium chloride to make the calcium ion concentration 18mmol / L, adjust by adding hydrochloric acid and sod...

Abstract

The invention discloses a composition of banana oligosaccharide and dietary fibre, a preparation method and an application thereof. The composition comprises banana oligosaccharide, soluble dietary fibre and insoluble dietary fibre, wherein the proportion of the banana oligosaccharide to the soluble dietary fibre to the insoluble dietary fibre is 2.5:1:2 or 2:2:2.In the invention, the banana oligosaccharide is obtained by pulping the fruit flesh of bananas, leaching by water, precipitating by ethanol and freeze-drying in vacuum; the soluble and insoluble dietary fibre of the bananas is obtained by carrying out zymohydrolysis on the fruit residues of the bananas. The composition has the effect of relaxing bowels of a common purge, is mild, does not have stimulation property, overcomes side effects caused by common rhubarb and anthraquinone class purges, can exert the physiological function of preventing colonic and rectal cancers, cardiovascular diseases and the like of the dietary fibre and achieves the aims of retaining water, lubricating and keeping high penetrability; because the composition is natural, safe and effective, the composition is especially suitable for relieving the constipation symptoms of dry, dense and clotty stool and difficult defecation of infants because of eating powdered milk.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a functional food and a preparation method thereof, in particular to a banana oligosaccharide and dietary fiber composition, a preparation method and application thereof. Background technique [0002] Constipation refers to the state of unsmooth defecation, including dry feces and poor excretion, and feces that are not dry and difficult to expel. Generally, it refers to less than 2 to 3 bowel movements per week. According to the etiology, it can be divided into organic constipation and functional constipation. The former is caused by intestinal and systemic diseases; the latter refers to rectal constipation caused by abnormal defecation reflex or obstruction and colonic constipation caused by slow colonic peristalsis. Clinically said constipation mainly refers to functional constipation. Rhubarb and anthraquinone laxatives are often used in the treatment of constipation, b...
