Embodiment 1

[0031] A method for extracting soluble dietary fiber from pineapple pomace, comprising the following steps:

[0032] (1) Degreasing: Screen and clean the pineapple pomace discarded in fruit juice processing, blanch in hot water at 85°C for 3 minutes, then dry with hot air at 45°C for 48 hours; pass through a 40-mesh sieve after crushing, and use a material-to-liquid ratio of 1:5 (m / v) Add petroleum ether, stir and soak at room temperature for 1 hour, filter with suction, and air-dry to obtain the degreased material;

[0033] (2) Double-enzyme hydrolysis: add distilled water to the degreased material prepared in step (1) at a material-to-liquid ratio of 1:30 (m / v), adjust the pH value of the material liquid to 6.0, and add 1% of the weight of the degreased material α-Amylase, in a water bath at 50°C for 60 minutes, after cooling to 40°C, add papain with a weight of 0.1% of the weight of the degreased material, and bathe in water for 60 minutes; keep stirring during the period, ...

Embodiment 2

[0038] A method for extracting soluble dietary fiber from pineapple pomace, comprising the following steps:

[0039] (1) Degreasing: Screen and clean the pineapple pomace discarded in fruit juice processing, blanch in hot water at 90°C for 3 minutes, then dry with hot air at 50°C for 40 hours; pass through a 60-mesh sieve after crushing, and use a material-to-liquid ratio of 1:6 (m / v) Add petroleum ether, stir and soak at room temperature for 3 hours, filter with suction, and air-dry to obtain the degreased material;

[0040] (2) Double-enzyme hydrolysis: add distilled water to the degreased material prepared in step (1) at a material-liquid ratio of 1:30 (m / v), adjust the pH value of the material liquid to 7.5, and then add 2.5% of the weight of the degreased material α-amylase in a water bath at 75°C for 20 minutes, after cooling to 60°C, add papain with a weight of 0.3% of the weight of the degreased material, and bathe in water for 20 minutes; keep stirring during the period...

Embodiment 3

[0045] A method for extracting soluble dietary fiber from pineapple pomace, comprising the following steps:

[0046] (1) Degreasing: Screen and clean the pineapple pomace discarded in fruit juice processing, blanch in hot water at 90°C for 2 minutes, and dry with hot air at 55°C for 48 hours; crush and pass through an 80-mesh sieve with a material-to-liquid ratio of 1:3 (m / v) Add petroleum ether, stir and soak at room temperature for 4 hours, filter with suction, and air-dry to obtain the degreased material;

[0047] (2) Double-enzyme hydrolysis: Add 40 times the weight of distilled water to the degreased material prepared in step (1), adjust the pH value of the material solution to 6.5, add 3% α-amylase by weight of the degreased material, and bathe in water at 65°C for 40 minutes , after cooling to 55°C, add papain with 0.2% of the weight of the degreased material, and bathe in water for 30 minutes; stir continuously during the period, heat to 95°C for 5 minutes to kill the ...

Abstract

The invention relates to the field of agricultural product processing, and discloses a method for extracting soluble dietary fiber from pineapple pomace. In the extraction method of the present invention, soluble dietary fiber is extracted by treating pineapple skin dregs through degreasing, double-enzyme hydrolysis, shear modification, acid bath, alcohol precipitation, and drying. The extraction method is simple and the cost is low, and the soluble dietary fiber can be obtained The finished product yield is as high as 19.22%. The method of the invention can provide a reference basis for the extraction of soluble dietary fiber in pineapple pomace, and has a good application prospect.

Description

technical field [0001] The invention relates to a method for extracting soluble dietary fiber, in particular to a method for extracting soluble dietary fiber from pineapple pomace, and belongs to the field of agricultural product processing. Background technique [0002] Dietary fiber is currently internationally recognized as a functional food base. It is called the "seventh nutrient" after carbohydrates, proteins, fats, vitamins, minerals and water. It has the functions of preventing obesity, enhancing immunity, Preventing diabetes, preventing colon cancer and inhibiting harmful bacteria is one of the main raw materials for the development of functional foods. According to the different solubility in water, dietary fiber can be divided into two categories: insoluble dietary fiber (Insoluble dietary fiber, IDF) and soluble dietary fiber (Soluble dietary fiber, SDF). Insoluble dietary fiber has water-holding and imbibition effects. After ingestion, it can increase the body'...
