Embodiment 1

[0037] A method for extracting seaweed dietary fiber, comprising the steps of:

[0038] (1) Pretreatment

[0039] After the seaweed is selected to remove impurities and washed with water, the wet seaweed is placed in the steam explosion tank, and saturated steam is introduced until the temperature in the tank reaches 90°C, and after maintaining for 7 minutes, the supply of saturated steam is stopped, and the steam explosion tank is passed Inject high-pressure air until the pressure in the steam explosion tank reaches 1.5Mpa, and release it under reduced pressure instantly. After drying the obtained product in a drying oven for 1 hour at 61°C, crush it to a particle size of 180 mesh or less, add water and soak it at room temperature for 0.7 hours , the ratio of material to water is 1:7, and the mixed solution of broken seaweed is obtained.

[0040] (2) Enzymolysis

[0041] Add compound enzyme A to the above broken seaweed mixture, add disodium hydrogen phosphate-citric acid b...

Embodiment 2

[0049] A method for extracting seaweed dietary fiber, comprising the steps of:

[0050] (1) Pretreatment

[0051] After the seaweed is selected to remove impurities and washed with water, the wet seaweed is placed in the steam explosion tank, and saturated steam is introduced until the temperature in the tank reaches 85°C, and after maintaining for 5 minutes, the supply of saturated steam is stopped, and the air explosion tank is passed Inject high-pressure air until the pressure in the steam explosion tank reaches 0.9Mpa, and release it under reduced pressure instantaneously. After drying the product at 57°C in a drying oven for 1.5h, crush it to a particle size of less than or equal to 160 mesh, add water and soak it at room temperature for 0.6 h, the ratio of material to water is 1:6, and the mixed solution of broken seaweed is obtained.

Embodiment 3

[0061] A method for extracting seaweed dietary fiber, comprising the steps of:

[0062] (1) Pretreatment

[0063] After the seaweed is selected to remove impurities and washed with water, the wet seaweed is placed in the steam explosion tank, and saturated steam is introduced until the temperature in the tank reaches 96°C, and after maintaining for 9 minutes, the supply of saturated steam is stopped, and the air explosion tank is ventilated. Inject high-pressure air until the pressure in the steam explosion tank reaches 1.8Mpa, and release it under reduced pressure instantaneously. After drying the obtained product in a drying oven at 64°C for 0.5h, crush it to a particle size of less than or equal to 200 mesh, add water and soak it at room temperature for 0.9 h, the ratio of material to water is 1:9, and the mixed solution of broken seaweed is obtained.

Abstract

The invention provides an extraction method of seaweed dietary fibers. The method comprises the steps of firstly performing steam explosion cell disruption pretreatment on seaweed, then performing three times of enzymolysis, acid and alkali treatment, and fishy smell elimination, activation and extraction in sequence to obtain the seaweed dietary fibers. A method combining chemical reagents and enzyme reagents is adopted by the invention to extract the seaweed dietary fibers, and the extraction rate of the dietary fibers is high; the extraction method provided by the invention has the advantages that the damage to soluble dietary fibers is small, the soluble dietary fiber content in the prepared dietary fibers is high, the expansibility and water-holding power of the dietary fibers are relatively high, and no fishy smell exists; the prepared dietary fibers have relatively good physiological functions and is beneficial to intestinal tract movement, saccharides and lipid metabolism and the like.

Description

technical field [0001] The invention relates to a method for extracting seaweed dietary fiber, which belongs to the technical field of deep processing of marine resources. Background technique [0002] Seaweed is a low-level cryptogamous plant that grows in the ocean. It is the original organic producer and natural enricher of inorganic substances in the ocean. Studies have shown that whether it is red algae, brown algae or green algae, it is rich in dietary fiber. . my country has a long coastline, a vast area of ​​tidal flats, rich algae resources and various varieties, such as sargassum, Gracilaria, Eucheuma, kelp, etc., which belong to seaweed marine plants, rich in alginate, cellulose, hemicellulose, vitamins, minerals, etc. Substances, etc., and the content of soluble polysaccharides is quite high, which is a high-quality raw material for extracting high-activity dietary fiber. Among them, seaweed that cannot be eaten directly is mainly used as raw materials for the p...
