First, look at the batch number: "food standard" is the batch number of food, but it is only in accordance with the food standard, but its health effect has not been certified by the authority. According to the relevant regulations, the "food" batch number is not allowed to publicize its health care. The effect of this type of spirulina is to play a big "?" in the health effect!


Second, look at the variety: There are many varieties of spirulina, of which the quality of Spirulina platensis is the best, although they are all spirulina, but the spirulina platensis is easily absorbed by the body because of its unique polysaccharide structure cell wall, which leads to The difference between the health effects of ordinary spirulina and the common spirulina is similar to that of German shepherd and common grass dog.


Third, look at the process: The technological level of the enterprise largely determines the quality of the product, especially the drying process of spirulina. Large-scale enterprises adopt mechanical drying, fast mechanical drying, low loss of nutrients, purity can be guaranteed, and will not suffer secondary pollution; workshop-type enterprises use natural drying and drying due to factors such as scale cost, and spirulina is irradiated by ultraviolet rays. The loss of post-active protein and phycocyanin is large, which affects the quality of the product. It is difficult to ensure the hygiene and purity of the product in open-air operation.


Fourth, look at the price: The price of the market is a basis for judging the quality of the product. A company's pricing will carefully consider its own profit and the market competitiveness of its products, thus formulating a reasonable product price. As the saying goes: "There is nothing wrong with buying the wrong one," "first-class price first class." To be sure: If you buy a so-called "wild Ganoderma lucidum" at a lower price than artificially cultivated Ganoderma lucidum, please consider the authenticity of this so-called wild Lingzhi.

How to choose spirulina


V. Look at the color: 1. The deeper the color, the higher the nutrient content of spirulina. According to the general principles of botany, the color reflects the sufficient degree of photosynthesis of algae. The more photosynthesis, the more dry matter accumulation, the effective ingredients. The higher the content. Good spirulina is cyan or dark green, yellow green and grass green, and blue and green is the worst. Even in the same brand of products, the color of spring, autumn and winter products and summer are different. 2, look at the purity, high-quality spirulina products are selected through the selection of equipment, eliminating the other impurities in the growth of spirulina, the selected pure spirulina powder is only 70% of the original spirulina powder. Therefore, the color of high-quality spirulina is uniform, and no other impurities are allowed in between. However, there are some illegal underground workshops that use dyeing methods to cover up the impurities of the product. Remember! Chemical dyes are extremely harmful to the human body!!! 3, look at the color dissolved in water, spirulina dissolved in warm water, if it appears blue-green, indicating that the spirulina spirulina has been destroyed, it is certain that this spirulina is dried by the sun, this kind of Spirulina should be purchased with caution.


VI. Look at the production area: The ancestors of spirulina are Central Africa and Mexico, suitable for growing in tropical and subtropical regions. In China, only the light and temperature conditions south of the Yangtze River can make spirulina grow naturally. Spirulina is in the area north of the Yellow River. Only a short summer can grow normally. In spring and autumn, chemical fertilizers such as urea are used to promote their growth. Therefore, the spirulina contains high nitrate content, which does not meet the requirements of modern food, “natural” and “no pollution”. .


VII. Look at the visibility of the company: An excellent company pays great attention to its own corporate image. Its corporate information and information about its products are also seen as a public relations image of the company in various media. Internet friends can also easily search for information about related products on the Internet. If you can't find the so-called "brand" products, please buy them carefully.
