preparation example Construction

[0014] The preparation method of walnut shell dietary fiber of the present invention specifically includes the following steps:

[0015] A. Pre-treatment: After drying and crushing the walnut shells, add distilled water to steam at 110-120°C for 10-20 minutes, then concentrate, dry, and crush the raw materials, and then slowly spray and add water while stirring to adjust the moisture content of the raw materials to 100 ~150%, then stop stirring and take out the raw materials, seal for 5-30min, then put the raw materials into the steam explosion device, raise the pressure to 0.8~1.0Mpa in 1~4min, release the pressure instantly after holding the pressure for 50~80s, take out the raw materials and add The NaOH solution with a mass percentage concentration of 2.5~3 is ultrasonically extracted at 160~200W for 25~30min to obtain the extract, and then the extract is centrifuged at 5500~6000r / min for 3~4min and filtered, and the filter residue is taken as the dietary fiber raw material;

Embodiment 1

[0028] A. Pre-treatment: The walnut shells are dried and crushed and then steamed with distilled water at 110°C for 10 minutes, then concentrated, dried and crushed. Then the raw materials are slowly sprayed with water while stirring to adjust the moisture content of the raw materials to 100%, and then stop Stir and take out the raw materials, seal for 5 minutes, then put the raw materials into the steam explosion device, raise the pressure to 0.8Mpa in 1 min, and release the pressure instantly after holding the pressure for 50 seconds. Take out the raw materials and add the NaOH solution with a concentration of 2.5 mass percentage to ultrasonic at 160W. Extract the extract for 25 minutes, and then centrifuge the extract at 5500 r / min for 3 minutes and filter, and take the filter residue as the dietary fiber raw material;

Abstract

The invention discloses a preparation method of walnut shell dietary fiber, which comprises pretreatment, semi-finished product preparation, purification and posttreatment. Also disclosed is a walnut shell dietary fiber prepared according to the preparation method of the walnut shell dietary fiber. The method of the present invention adopts the method of combining high-temperature cooking treatment, steam explosion treatment and ultrasonic treatment on the raw material during pretreatment, which can effectively destroy the structure and organization of the raw material and fully expose the contents. The raw material after pretreatment not only has It is beneficial to enhance the enzymatic hydrolysis effect of hydrolase, so that the enzymatic hydrolysis is more sufficient to improve the purity of the finished product, and can effectively improve the palatability of the finished product; after enzymatic hydrolysis, it is purified to further improve the purity, and the finished product has high purity The advantages; the walnut shell dietary fiber of the present invention also has the advantages of small fiber particle size, strong water holding capacity and strong swelling capacity.

Description

Technical field [0001] The invention belongs to the technical field of dietary fiber preparation, and specifically relates to a preparation method of walnut shell dietary fiber and walnut shell dietary fiber. Background technique [0002] Dietary fiber is an important non-nutrient. It is a type of non-starch polysaccharides and oligosaccharides in carbohydrates and other indigestible parts. It cannot be digested and absorbed by the human gastrointestinal tract, nor can it produce energy. However, in recent years, more and more studies have shown that dietary fiber intake is closely related to human health. Sufficient intake of dietary fiber will reduce the risk of constipation, obesity, diabetes, cardiovascular disease and intestinal cancer. For example, dietary fiber can absorb a large amount of water in the intestine, keep the stool soft, effectively activate the beneficial bacteria in the intestine, promote the proliferation of beneficial bacteria, and create intestinal ecolog...
