Problems solved by technology

However, according to the theory that the solute in the solution or the colloidal particles in the sol are in a state of motion all the time, the nano-selenium particles stored in the state of solution or sol may collide with each other all the time, resulting in irreversible aggregation, and finally the formation of organisms that cannot Utilized gray or black elemental selenium
Adding a polymer solution is only a method of softly blocking nano-selenium particles, which can only slow down the aggregation process of nano-selenium, and often can only maintain a stable state for several months

Embodiment 1

[0031] Take 10 grams of agarose, add it to 100mL of water, pre-soak for 1 hour, and heat to 90°C to completely dissolve the agarose, filter it while it is hot, and keep the filtrate. Take 0.1g of nano-selenium, the particle size of which is not more than 1000 nanometers, add it to the aforementioned hot agarose solution, and keep stirring until the red color is uniformly dispersed in the system. Then add 0.2 g of citric acid, stir rapidly while hot until the citric acid solid cannot be seen. Pour the hot agarose liquid with various components into the mold, and cool it down to room temperature naturally to form a jelly-like selenium-enriched marine polysaccharide composition. figure 1 The morphology of nano-selenium in the selenium-enriched marine polysaccharide composition prepared in this example is shown.

Embodiment 2

[0033] Take 2.5 grams of agar, add it to 100mL of water, pre-soak for 5 hours, take out the agar and heat it to 95°C to completely melt the agar, filter it while it is hot, and keep the filtrate. Take 0.05g of nano-selenium, whose particle size does not exceed 1000 nanometers, add it to the aforementioned hot agar solution, and keep stirring until the red color is uniformly dispersed in the system. Then add 0.2 g of citric acid and 0.1 g of sodium citrate, and stir rapidly while hot until the solids of citric acid and sodium citrate cannot be seen. Pour the hot agar solution with various components into the mold, and let it cool down to room temperature naturally to form a figure 2 The jelly-like selenium-enriched marine polysaccharide composition shown.

Embodiment 3

[0035] Take 10 grams of agarose, add it to 100mL of water, pre-soak for 1 hour, and heat to 90°C to completely dissolve the agarose, filter it while it is hot, and keep the filtrate. Add 0.2 g of sodium selenite and 1.2 g of ascorbic acid to the aforementioned hot agarose solution, and keep stirring until the red color in the system does not deepen and the dispersion is uniform. Then add 0.2 g of citric acid, stir rapidly while hot until the citric acid solid cannot be seen. Pour the hot agarose solution added with various components into the mold, cool naturally to room temperature, and then put it in a refrigerator to refrigerate to form a jelly-like selenium-enriched marine polysaccharide composition.

Abstract

The present invention discloses a selenium-enriched marine polysaccharide composition and a preparation method thereof. The composition presents a solid gelatinized shape at room temperature and elemental selenium is evenly dispersed within the composition. The composition consists of the following components in parts by weight: 100-10,000 parts of marine polysaccharides, 1-100 parts of red nano-elemental selenium, 100-1,000,000 parts of water, 0-50,000 parts of citric acid and 0-50,000 parts of metal salts. The composition can physically isolate the nano-selenium particles, prevents the aggregations of the particles due to contacting with each other, and thereby improves the stability of the nano-selenium.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a selenium-enriched marine polysaccharide composition and a preparation method thereof. Background technique [0002] Selenium is an essential nutritional trace element with a wide range of biological activities. Selenium plays an important role in the prevention of cardiovascular disease, anti-oxidation, anti-aging, anti-virus, anti-cancer, immune function regulation, etc.; selenium deficiency is closely related to dozens of common diseases. In 1973, the World Health Organization announced that selenium is an indispensable trace element in human and animal life activities; in 1988, the Chinese Nutrition Society listed selenium as one of the 15 daily dietary essential nutrients. Reasonable supplementation of selenium and maintaining a reasonable metabolism of selenium in the body are crucial to maintaining normal physiological functions of the human body. ...
