Problems solved by technology

However, there is no research on the use of mussel extracts for selenization, and the research on nano-selenium is limited to polysaccharides as templates.
Due to the single template, the control effect is poor, and the template concentration in the reaction system is required to be low (about 100-400ppm), which brings troubles to subsequent concentration and drying.

[0018] Preparation of nano-selenium mussel powder

[0019] 1. Pre-treatment of mussels:

[0020] After the mussels are harvested, wash them with clean water to remove the silk, impurities, etc., control the water, put them in a tissue masher for homogenization, extract the slurry with 95% ethanol (4 times the volume) at 50°C for 6 hours, and repeat twice , filtered to remove the fat, the filter cake was rinsed with a small amount of ethanol, vacuum-dried, crushed and passed through a 100-mesh sieve to obtain defatted mussel powder.

Abstract

The invention discloses a preparation method of nano-selenium mussel powder, and belongs to the technical field of aquatic product processing. The method comprises the following steps of pre-processing of mussels, co-extracting of mussel protein and polysaccharides and nano-selenizing of a mussel protein and polysaccharide compound. According to the preparation method of the nano-selenium mussel powder, the protein and polysaccharide co-extracting technology is adopted, the mussel protein and polysaccharide compound extract is obtained, and the antioxidant activity in vitro is greatly increased through the synergistic effect of the two ingredients. The mussel polysaccharide and protein peptides act synergistically and jointly serve as templates to regulate and control aggregation of elemental selenium, the regulation and control capacity is enhanced, the particle size of selenium is smaller and more uniform, the antioxidant activity in vitro is greatly increased, the concentration of the templates of a reaction system is higher, and the production efficiency of subsequent concentrating and drying is improved.

Description

technical field [0001] The invention relates to a preparation method of mussel powder, in particular to a preparation method of nano-selenium mussel powder, which belongs to the technical field of aquatic product processing. Background technique [0002] According to existing literature reports, both mussel protein peptides and mussel polysaccharides have antioxidant activity in vitro, so a lot of research has been done on the extraction of mussel protein, enzymatic hydrolysis and extraction of mussel polysaccharides, but these studies are all aimed at However, there are no reports on the extraction process of simultaneous extraction of protein and polysaccharides and the synergistic antioxidant activity of protein peptide-polysaccharide complexes. [0003] Selenium is an important trace element necessary for human life. It has many functions such as enhancing the body's immunity, resisting free radical damage, preventing diseases and regulating thyroid function. Studies ha...
