Embodiment 1

[0021] A method to extract alginic acid, follow the steps below:

[0022] (1) Ponylonase interpretation treatment: In the exposure reactor that puts the water into a mixing device, invest 4g / L papaya enzyme in the stirring situation, and after it is completely dissolved, then invest 200g / L ponyta algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder and put it into ponyta algae powder.Warm to 55 ° C, 2 h for the insulation enzyme, that is, stop stirring; pour the ponyta algae powder after the enzymatic dismissal, and wash the ponyta algae powder with the enzymatic dismissal with water;

[0023] (2) Establytic ponyta powder and then extract sea alginic acid with conventional processes.

[0024] The extraction rate of its alginic acid was detected by about 94.29 %, and the obtained alginic acid products met the GB1976-80 standards.

[0025]

Embodiment 2

[0027] A method to extract alginic acid, follow the steps below:

[0028] (1) Ponylonase interpretation treatment: In the exposure reactor that puts the water into a stirring device, when the stirring is stirred, invest 6g / L papaya enzyme, and after it is fully dissolved, then invest 300g / L ponytail algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder.Warm to 60 ° C, 4 h for the insulation enzyme, that is, stop stirring; pour the ponyta algae powder after the enzymatic dismissal, and wash the ponyta algae powder with the enzymatic dismissal with water;

[0029] (2) Establytic ponyta powder and then extract sea alginic acid with conventional processes.

[0030] The extraction rate of its alginic acid was detected by about 93.18 %, and the obtained alginic acid products met the GB1976-80 standards.

[0031]

Embodiment 3

[0033] A method to extract alginic acid, follow the steps below:

[0034] (1) Ponylonase interpretation treatment: In the exposure reactor that puts the water into a mixing device, when the stirring is stirred, invest 5g / L papaya enzyme, and after it is fully dissolved, then invest 100g / L ponytail algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder and then put it and ponyta algae powder.Warm to 50 ° C, the insulation enzyme disintegration 1 h, that is, stop the stirring; pour the ponyta algae powder after the enzymatic dismissal, and wash the ponyta algae powder with the enzymatic dismissal with water;

[0035] (2) Establytic ponyta powder and then extract sea alginic acid with conventional processes.

[0036] The extraction rate of its alginic acid was detected by about 94.08 %, and the obtained alginic acid products met the GB1976-80 standards.

Abstract

A method for extracting alginic acid belongs to the technical field of marine organism extraction. The method comprises the following steps: (1) enzymatic hydrolysis pretreatment of sargassum: adding water into an openmouthed reactor with a stirring device, adding 4-6 g/L of papain with stirring, after papain is fully dissolved, adding 100-300 g/L of sargassum powder, heating to 50-60 DEG C, keeping the temperature for performing enzymatic hydrolysis for 1-4 h, then stopping stirring; pouring out sargassum subjected to enzymatic hydrolysis, filtering, washing with water to obtained sargassum subjected to enzymatic hydrolysis pretreatment; and (2) extracting alginic acid from the sargassum subjected to enzymatic hydrolysis pretreatment by employing a conventional technology. The method provided by the invention helps to improve the extraction yield of alginic acid, reduce resource consumption and reduce production cost. By utilizing papain to perform enzymatic hydrolysis pretreatment on the raw material sargassum and then employing the conventional technology to extract alginic acid, the extraction yield of alginic acid is substantially improved and reaches 90% or more.

Description

Technical field [0001] The present invention is a marine biological extraction technology field, and it involves a method of extracting sea alginic acid. [0002] Background technique [0003] The alginic acid is a polysaccharide carbohydrate extracted from brown algae plants such as the kelp.In recent years, it has been paid more attention to its extensive use of alginic acid.According to relevant data reports, in food workers [0004] Industry, sea alginic acid is used to make artificial foods such as artificial fruits, artificial eggs, jelly, etc., and is also used as food thickeners, beverage antifreeze, sinking agent, school taste agent, and ice cream.Food add [0005] Add doses.In terms of disease prevention, alginic acid has the effects of lowering the cholesterol content in the human body, clearing blood vessels, reducing blood viscosity, and softening blood vessels.In the textile industry, printing and dyeing [0006] Both flowers and pulp need to be used in large quanti...
