Preparation method of high-chromium spirulina powder

Abstract

The invention relates to a preparation method of high-chromium spirulina powder. The method comprises the following steps: 1) preparing a chromium working liquid for later use: adding 2.5g of chromium chloride hexahydrate in each liter of water, wherein the working liquid is dark green after being prepared, and the pH value is between 5-6; b) collecting common spirulina from a culture pond by using a screen or a filter cloth; c) cleaning the collected spirulina by using clear water; d) putting the cleaned spirulina into the chromium working liquid prepared in the step a) to perform high chromizing, and uniformly mixing, wherein the spirulina biomass reaches 20g / l; controlling the liquid temperature at 20-25 DEG C, culturing for 60min, and continuously stirring in the culturing period; e) collecting the high chromized spirulina from the working liquid by using the screen or the filter cloth; and f) cleaning the high chromized spirulina by using the clear water, and drying. Compared with the prior art, the spirulina powder is high in chromium content; and the process is simple, the production period is short, the contained chromium element has biological activity and can be easily absorbed by a human body.

Description

technical field [0001] The invention relates to a preparation method of high-chromium spirulina powder, which belongs to the technical field of health care products and also belongs to the technical field of biopharmaceuticals. Background technique [0002] Spirulina is the ancient plant closest to animals in the biological chain. Its unique cell structure enables it to be directly digested and absorbed by the human body without going through a series of transformation processes. People with poor gastrointestinal function can also digest and absorb well; at the same time, spirulina is an alkaline natural plant food. Continuous consumption can change the acidity of the human body and maintain an alkaline body. So as to better promote immune function to play a role. Spirulina helps eliminate various causes of disease, prevent hidden dangers of various diseases, comprehensively regulate human body functions, and improve cell metabolism. [0003] Chromium is one of the essenti...

Problems solved by technology

[0004] However, the chromium content of existing spirulina is relatively low, and it is difficult to achieve the purpose of lowering blood sugar. While taking spirulina, it also takes more auxiliary materials that the human body does not need. Long-term use will have adverse effects on the human body, especially Existing spirulina is very vulnerable to air pollution, high water hardness and other factors in the production process, so that the amount of heavy metals such as lead and mercury in spirulina exceeds the standard. When taking spirulina for a long time, heavy metals are also accumulated in the body, which cannot achieve health Moreover, the existing spirulina oral preparations have destroyed the nutritional content of spirulina in the production process, which greatly reduces the health care effect of spirulina; these problems in the prior art have always been an important problem for those skilled in the art to study and solve. One of the subjects

[0005] The Chinese invention patent with the publication number CN102845781B provides a method for preparing chromium-rich instant spirulina. In the disclosed technical solution, only 0.13g-0.15g of trichloride is added to 700kg of water when the nutrient solution is prepared during the cultivation of spirulina. Chromium, so it is impractical to advertise it as chromium-rich spirulina, and the entire technical solution is extremely complicated, and the production cycle is long, which is not conducive to reducing costs and is environmentally friendly.
