Embodiment 1

[0020] A preparation method of sargassum wall-broken acidification product, comprising the following steps:

[0021] (1) Cut Sargassum into small pieces of 2cm, soak in water for 12 hours, add 15% sodium carbonate solution to 20cm of Sargassum, and then stir for 4 hours at a temperature of 40°C and a pH of 8.6. into a sargassum paste;

[0022] (2) Adjust the pH of the sargassum paste in step (1) to 3 with glacial acetic acid under stirring, and flocs start to precipitate, and then stop stirring after stirring for 1 hour;

[0023] (3) Filter the floc in step (2) with a 20-mesh filter cloth, centrifuge and dehydrate, and then dry at 80°C to obtain Sargasso wall-broken acidified product.

Embodiment 2

[0025] A preparation method of sargassum wall-broken acidification product, comprising the following steps:

[0026] (1) Cut Sargassum into small pieces of 2 cm, soak in water for 24 hours, add 2% sodium carbonate solution to soak the Sargassum 20 cm, and then stir for 5 hours at a temperature of 80 ° C and a pH of 8, the solution into a sargassum paste;

[0027] (2) Adjust the pH of the sargassum paste in step (1) to 2 with glacial acetic acid under stirring, and flocs start to precipitate, and then stop stirring after stirring for 1 hour;

[0028] (3) Filter the floc in step (2) with a 20-mesh filter cloth, centrifuge and dehydrate, and then dry at 80°C to obtain Sargasso wall-broken acidified product.

Embodiment 3

[0030] A preparation method of sargassum wall-broken acidification product, comprising the following steps:

[0031] (1) Cut the sargassum into 2cm pieces, soak in water for 20 hours, add 8% sodium carbonate solution to soak the sargassum 20cm, and then stir for 3 hours at a temperature of 60°C and a pH of 8.2. into a sargassum paste;

[0032] (2) Adjust the pH of the sargassum paste in step (1) to 5 with glacial acetic acid under stirring, and flocs start to precipitate, and then stop stirring after stirring for 1 hour;

[0033] (3) Filter the floc in step (2) with a 20-mesh filter cloth, centrifuge and dehydrate, and then dry at 80°C to obtain Sargasso wall-broken acidified product.

Abstract

The invention discloses a preparation method of a ruptured acidified substance of a sea grape. The method comprises the following steps of (1) cutting the sea grape into slices, soaking by water for 12-24 hours, adding 2-15% of sodium carbonate solution to soak the sea grape, agitating until the solution becomes sea grape paste under the conditions that the temperature is 40-80 DEG C and the pH is 8-8.6; (2) adjusting the pH of the sea grape paste in the step (1) to 2-5 by glacial acetic acid under an agitating state,, agitating for one hour when floccules begin to be separated out and stopping agitating; and (3) filtering, dewatering and baking the floccules in the step (2) to obtain the ruptured acidified substance of the sea grape. In addition, the invention also discloses the ruptured acidified substance of the sea grape prepared by the method; and the ruptured acidified substance of the sea grape can be used for cultivation of aquatic products, especially can be used as a feed additive for cultivating shrimps, and can obviously improve growth and immunity of prawns.

Description

technical field [0001] The invention relates to a method for breaking and acidifying sargassum walls and a broken acidifying product of sargassum obtained by the method. Background technique [0002] Sargassum is a class of seaweed in brown algae, belonging to Phaeophyta, Carragees, and Sargassumaceae. Sargassum is a temperate seaweed with a large body and a height of more than 1m. It is distributed in the South and North Seas of my country, and Guangdong and Guangxi have the highest yields, and the general harvest period is from March to May. Distributed in the intertidal and subtidal shallow water areas, it is the dominant species in this water area and is very rich in resources. [0003] The production of Sargassum in Hainan is large, but it has not been developed and utilized, and has not produced economic value. At present, Sargassum is in a state of self-destruction. When Sargassum grows, it absorbs a large amount of nitrogen and phosphorus in seawater, reducing the...
