Embodiment 1

[0021] The preparation method of present embodiment 1 comprises the following steps:

[0022] (1) Take 100g of Shuifa kelp and grind it into pieces (1-10mm), add water at 30°C to 1000ml.

[0023] (2) Add 5.6g of EDTA, 3g of KOH with a purity of 90%, and slowly stir for 2 hours. It can be observed that the seaweed epidermis is separated from the subcutaneous structure, the subcutaneous tissue is swollen and dissolved, and becomes a sol containing kelp peel.

[0024] (3) Continue to stir and add 3 g of ferrous sulfate 7 hydrate to the agitator. After stirring evenly, add 4 ml of 30% hydrogen peroxide. Later, add 0.6 g of VC powder. The viscosity of the reactant sol increases first, then drops rapidly, then stops stirring and filters.

[0025] (4) Add 10g boric acid in the filtrate to prevent it from spoiling.

Embodiment 2

[0027] The preparation method of present embodiment 2 comprises the steps:

[0028] (1) Take 200g of Shuifa kelp and grind it (1-10mm), add water at 30°C to 400ml.

[0029] (2) Add EDTA11.2g, 90%KOH6g, under the strong stirring of the agitator with blades at 5000 revs / min at the rotating speed, the agitated matter becomes a high-viscosity colloid after 2 to 10 minutes.

[0030] (3) Under strong stirring, add 6 g of ferrous sulfate 7 hydrate, 8 ml of 30% hydrogen peroxide, and 1.2 g of VC powder to the stirring material successively. The viscosity of the sol increases first and then decreases. Add water to 2000 ml, stop stirring, and filter.

[0031] (4) Add 20g boric acid to the seaweed liquid to prevent it from decaying.

Embodiment 3

[0033] The preparation method of the present embodiment 3 is to get 200g of fresh sea cabbage, wash and mince (1-10mm), and add 400 milliliters of clear water. All the other are the same as example 2.

Abstract

The invention provides a method for hydrolyzing seaweed. The method is as follows: fresh or water expanded seaweed is shattered; ethylenediamine tetracetic acid, potassium hydroxide or sodium hydroxide, ferrous sulfate, hydrogen peroxide and vitamin C are sequentially added while the seaweed is stirred; and after filtration, the filtrate is added with boric acid or borate, and finally seaweed hydrolysate can be obtained. The invention has simple preparation method and required equipment, seaweed polysaccharides can be fast degraded into micromolecules, and the activity of natural active substances of the seaweed can be maintained.

Description

Technical field: [0001] The invention relates to the fields of food, medicine, chemical industry, agriculture and the like, and is particularly related to a method for hydrolyzing seaweed. Background technique: [0002] Seaweed is a renewable resource, which is widely used in food, medicine, chemical industry and agriculture. Seaweed includes kelp, sea cabbage, sargassum, kelp, ascophyllum, and kelp, among others. [0003] In the field of agriculture, seaweed liquid fertilizer is receiving widespread attention as a new type of fertilizer. [0004] Seaweed is the product of hydrolyzed seaweed, and it is the basic material of seaweed liquid fertilizer. Among the key technologies of seaweed hydrolysis, the small molecularization of seaweed polysaccharides and the maintenance of the activity of seaweed natural active substances are one of the important goals for the development of high-quality seaweed and seaweed liquid fertilizer production technology. [0005] The alginic a...
