Preparation method of selenium-rich quick-frozen spiral algae

Abstract

The invention provides a preparation method of selenium-rich quick-frozen spiral algae. The method comprises the steps that: (1) a spiral algae strain liquid is prepared, wherein: 1.1, a culture medium is prepared according to the components and the ratio presented below; and 1.2, the spiral algae strain liquid is prepared; (2) spiral algae is cultured, wherein: 2.1, a nutrient solution is prepared; and 2.2, according to a ratio that 25kg of the spiral algae strain liquid is added into every 700kg of the nutrient solution, the nutrient solution and the spiral algae strain liquid are added into a culturing tank for carrying out culturing; and the spiral algae is collected; and (3) the quick-frozen product is prepared, wherein: 3.1, the collected fresh spiral algae is prepared into semi-finished product spiral algae; 3.2, the semi-finished product spiral algae is frozen and is stored in a quick-freezing storage with a temperature of -28 DEG C to -30 DEG C, such that the selenium-rich quick-frozen spiral algae is obtained. According to the invention, the entire method, from spiral algae strain liquid is prepared to the selenium-rich quick-frozen spiral algae is obtained, causes no pollution. A pure spiral algae instant food product is provided for people. When the product is taken for a long time, a real health-caring function is provided, and no adverse influence is caused on body.

Description

technical field [0001] The invention relates to spirulina, which is a preparation method of selenium-enriched quick-frozen spirulina. Background technique [0002] Spirulina is a health product with high nutritional value. Long-term consumption has anti-tumor, anti-virus, anti-radiation, blood sugar regulation, anti-thrombosis, liver protection, anti-fatigue, improvement of human immunity and correction of iron deficiency anemia, etc. With the continuous improvement of people's living standards, spirulina is gradually accepted by the public as a health product. However, at present, the edible varieties of spirulina on the market are generally tablets and capsules. Although these varieties have the advantage of long shelf life, the content of spirulina is relatively low. Excipients that are difficult to metabolize, long-term consumption will have adverse effects on the human body. At the same time, because spirulina is highly susceptible to pollution during the production ...

Problems solved by technology

However, at present, the edible varieties of spirulina on the market are generally tablets and capsules. Although these varieties have the advantage of long shelf life, the content of spirulina is relatively low. Excipients that are difficult to metabolize, long-term consumption will have adverse effects on the human body

At the same time, because spirulina is very susceptible to pollution during the production process, it is very easy to absorb various heavy metals, so that the content of heavy metals is relatively high

In particular, some companies add artificial dyes to increase the appearance of chlorophyll in spirulina, so that the heavy metal content seriously exceeds the standard. When this spirulina is used to make selenium-enriched products or other edible varieties, there is no guarantee that long-term consumption will cause no harm to the human body.
