Embodiment 1

[0044] 1 gram of chitosan was dissolved in an appropriate amount of 1% acetic acid solution, 0.4 gram of ascorbic acid was added, after fully dissolving, 100 mg of sodium selenite was added, and the reaction was stirred until the red color in the solution did not deepen any more, and nanometer elemental selenium sol was obtained. Another 100 g of sucrose was completely dissolved in 200 ml of deionized water to obtain a sucrose solution. The nano elemental selenium sol and the sucrose solution are fully mixed to prepare the powder spraying liquid. The powder spray liquid is spray-dried, the hot air inlet temperature of the spray dryer is 190°C, the outlet temperature is 110°C, and the gauge pressure at the atomizer is 2MPa. After spray drying, a reddish-brown powder nanometer elemental selenium / sucrose complex is obtained. The light reddish brown solid powder is observed under a scanning electron microscope (SEM), and the image is as follows figure 1 shown. The light reddish...

Embodiment 2

[0046] Dissolve 1 gram of sodium carboxymethyl cellulose in an appropriate amount of deionized water, add 0.6 gram of ascorbic acid, after fully dissolving, add 60 mg of selenium dioxide, stir and react until the red color in the solution does not deepen any more, and obtain nanometer elemental selenium sol. Another 150 grams of glucose was taken and completely dissolved in 250 ml of deionized water to obtain a glucose solution. The nano elemental selenium sol and the glucose solution are fully mixed to prepare the powder spraying liquid. The powder spray liquid is spray-dried, the hot air inlet temperature of the spray dryer is 180°C, the outlet temperature is 105°C, and the gauge pressure at the atomizer is 1.5MPa. After spray drying, a reddish-brown powdery nanometer elemental selenium / carboxymethyl cellulose composite was obtained.

Embodiment 3

[0048] Dissolve 1 gram of sodium alginate in an appropriate amount of deionized water, add 100 mg of sodium selenate, fully stir to dissolve, add 0.6 gram of sodium borohydride, stir and react until the red color in the solution no longer deepens, and obtain nanometer elemental selenium sol. Another 200 grams of chitosan oligosaccharides was completely dissolved in 500 ml of deionized water to obtain a chitosan oligosaccharide solution. The nano elemental selenium sol and the chitosan oligosaccharide solution are fully mixed to prepare a powder spraying solution. The spray powder liquid is spray-dried, the hot air inlet temperature of the spray dryer is 160°C, the outlet temperature is 85°C, and the gauge pressure at the atomizer is 1.5MPa. After spray drying, a reddish-brown powdery nanometer elemental selenium / chitooligosaccharide complex is obtained.

Abstract

The invention discloses an elemental selenium and sugar compound and a preparation method of the elemental selenium and sugar compound. The elemental selenium and sugar compound comprises nano elemental selenium and water-soluble sugar, wherein the ratio of the water-soluble sugar to the selenium is (1-10000):(1-10000) according to the dry weight. The preparation method comprises the following steps: (1), preparing the nano elemental selenium; and (2), mixing the nano elemental selenium with the water-soluble sugar to obtain a mixture; and (3), spray-drying the mixture, and thus obtaining a finished product. According to the elemental selenium and sugar compound, water-soluble monosaccharide or polysaccharide is used for replacing or partially replacing a macromolecular substance in the prior art, thus the defects of difficulty in dissolution and dewatering, time consumption and excessive energy consumption of the macromolecular substance can be well solved, and meanwhile, the elemental selenium and sugar compound has multiple physiological functions of the water-soluble monosaccharide or polysaccharide. The preparation method disclosed by the invention has the advantages of safety and controllability of quality of products, simple, convenient and stable production process, energy consumption reduction, waste emission reduction, and the like.

Description

technical field [0001] The invention belongs to the technical field of food additives, and in particular relates to a compound of elemental selenium and sugar and a preparation method thereof. Background technique [0002] Selenium is an essential nutritional trace element for the human body. It plays an important role in the prevention of cardiovascular diseases, anti-oxidation, anti-aging, anti-virus, anti-cancer, and immune function regulation. Selenium deficiency is closely related to dozens of common diseases. The human body cannot synthesize selenium by itself, and there is no tissue or organ that can retain selenium for a long time. Therefore, selenium can only be taken in from outside the body. 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 sele...
