Preparation method of pure-natural quick-frozen spiral algae

Abstract

The invention provides a preparation method of pure-natural 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 reproduction; and (3) the quick-frozen product is prepared. According to the invention, the entire method, from the spiral algae strain liquid preparation step is carried out to the quick-frozen product is obtained, causes no pollution. The obtained spiral algae food product has no fishy smell or odor, and has extremely low heavy-metal content. Nutrients in spiral algae are not damaged. Therefore, a pure spiral algae instant food product is provided for people.

Description

technical field

[0001] The invention relates to spirulina, which is a preparation method of pure natural quick-frozen spirulina. Background technique

[0002] Spirulina is rich in nutrients and has various functions such as anti-tumor, anti-virus, anti-radiation, regulating blood sugar, anti-thrombosis, protecting the liver, and improving human immunity. It has become one of the important health products for people. However, due to the fact that spirulina is easily polluted during the growth process, the purity of existing spirulina is not good, especially it is very easy to absorb various heavy metals, so that when people eat spirulina, they also take heavy metals and other substances into their bodies. , Long-term consumption will cause damage to human health. The heavy metal content in the growth process of spirulina mainly comes from the following aspects: water quality in the breeding process; air in the breeding process; nutrient solution used in the breeding process...
