Problems solved by technology

However, during the long-term processing process, the alginate, mannitol, water-soluble vitamins, minerals, etc. on the surface of the kelp are dissolved and lost, which makes the active substances in the seaweed powder greatly lost, and the seaweed polysaccharide is not degraded and is still high. Molecular state, difficult to be absorbed

Embodiment 1

[0030] The preparation method of a kind of active seaweed extract described in the present invention comprises the following steps:

[0031] (1) Select 1 kg of clean and mildew-free kelp, and remove algae and foreign matter;

[0032] (2) Take 5Kg tap water, adjust the pH to about 3 with sulfuric acid, immerse the kelp in stirring and rinsing for 1 hour;

[0033] (3) After the cleaned kelp is minced, add 8 kg of dilute sulfuric acid with a pH of 3 and homogenate together;

[0034] (4) Keep the kelp pulp obtained after homogenization at 125°C and 3 MPa for 1 hour, ripen and sterilize and degrade the polysaccharide components;

[0035] (5) adding ammonia water to the degraded algae slurry to adjust the pH to 6.5;

[0036] (6) Inoculate the pre-cultivated bifidobacterium strains in the seaweed slurry after pH adjustment at 3% by volume, and conduct anaerobic fermentation for 24 hours at 37°C;

[0037] (7) Add 0.3Kg of alginate oligosaccharides to the fermented slurry to prepare...

Embodiment 2

[0040] The preparation method of a kind of active seaweed extract described in the present invention comprises the following steps:

[0041] (1) Select 30kg of clean and mildew-free kelp, 70kg of hijiki, and remove miscellaneous algae and foreign matter;

[0042] (2) Weigh 600Kg of tap water, adjust the pH to about 3 with nitric acid, immerse the kelp in stirring and rinsing for 1.5 hours;

[0043] (3) After the cleaned kelp is minced, add 800 kg of dilute nitric acid with a pH of 3 and homogenate together;

[0044] (4) Keep the kelp pulp obtained by homogenization at 125°C and 3 MPa for 1 hour, ripen and sterilize and degrade the polysaccharide components;

[0045] (5) adding potassium hydroxide to the degraded algae slurry to adjust the pH to 6.5;

[0046] (6) Inoculate the pre-cultivated lactic acid bacteria strains at 4% by volume in the seaweed slurry after pH adjustment, and perform anaerobic fermentation for 24 hours at 37°C;

[0047] (7) Add 40 kg of alginate oligos...

Embodiment 3

[0050] The kelp with the same quality and quantity as in Example 2 was tested according to the above steps, wherein only the dilute acid added during washing and homogenization was replaced with tap water, and a control test was carried out. Then the seaweed slurry after high temperature and high pressure degradation was adjusted to pH After 6.5, the specific comparison is shown in Table 1.

Abstract

The invention provides a preparation method of an active seaweed extract. The method comprises the steps of: seaweed selecting, impurity removing, weak acid washing, mincing and homogenizing, curing and sterilization under high temperature and high pressure as well as polysaccharide component degradation, pH adjustment, probiotic fermentation, and adding of alginate oligosaccharide for blending. The obtained liquid product is an active seaweed extracting solution, or it can be prepared into active seaweed extract powder through drying, and the extracting solution and the extract powder are collectively called an active seaweed extract. The active seaweed extract prepared in the invention reserves algae iodate, mannitol, inorganic salts, trace elements and other components, and the proteinand polysaccharide components in seaweeds are degraded and easy to absorb. Added with probiotics, secondary metabolites, and low molecular weight seaweed polysaccharide, the active seaweed extract ofthe invention has better biological activity, and can remove harmful heavy metals so as to improve the security of the seaweed extract.

Description

technical field [0001] The invention relates to the field of seaweed extracts, in particular to a preparation method of active seaweed extracts. Background technique [0002] Brown algae are the main constituents in marine plants. The kelp, kelp, wakame, hijiki, etc. in the brown algae can be used for food and medicine; the plants of the genus Sargassum can be used as feed or fertilizer. In addition, food or medical raw materials such as algin, mannitol, iodine, potassium chloride, and algal starch can be extracted from brown algae such as kelp. [0003] Brown algae is rich in nutrients and active substances, and also contains vitamins A, B, C and trace elements such as selenium, cobalt, and chromium. At the same time, brown algae also contains a large number of non-nitrogen-containing organic compounds and unknown growth-stimulating hormones. Most of the minerals and trace elements contained in brown algae exist in the form of organic state, which is not easy to be oxidiz...
