If you are too troublesome, you don't have to do these two tests. That depends on personal experience to judge whether it is true or not, so how to judge:
1, manufacturer. Need to know its production history, production scale and production technology. Generally speaking, the older the manufacturer, the more trustworthy it is.
2, product specifications, general packaging. Some manufacturers' products are 0.2 grams per tablet, and some are 0.25 grams per tablet. You can't just look at the total price. You can compare the price of each tablet or gram and see the cost performance according to the price.
3. Be sure to choose Chlorella products without any additives and accessories. Some Chlorella products produced in China have additives such as magnesium stearate or silicon dioxide. Some people will add some sweeteners to make the taste better, which will not only mask the true taste of Chlorella, but also greatly reduce its purity. We must choose 100% purity.
4. Algae species. Chlorella can be subdivided into about 10 species. According to the analysis report of Chlorella species, Chlorella pyrenoidosa is the algae species with the highest nutritional value.
5. Chlorella is generally made into tablets for sale. If you see liquid Chlorella products, please do not buy them. The concentration is extremely low, mostly water, and liquid Chlorella products are easily oxidized. Chlorella health food in the global market is generally made into tablets (granules). If it is Chlorella powder, it is not recommended to buy it (some Chlorella powder products also add sweeteners to improve the taste), which is inconvenient to take, and some people may not like the taste of Chlorella. The granules are convenient to take and also have high digestion and absorption rate.
Chlorella must be processed before it can be eaten. Wild Chlorella is inedible. First of all, it is impossible to tell which is Chlorella with the naked eye, because there are thousands of kinds of algae, and most of them are green with the naked eye. So how to determine Chlorella? It must be determined by observing the morphological structure of cells with a microscope. Chlorella cells are only the size of human red blood cells and need a microscope 600 times to see clearly. Furthermore, wild algae will adsorb heavy metals in natural environments such as oceans, lakes and ponds, and will breed toxic algae (such as microcystins) during the growth process, which is the most important reason why wild algae cannot be eaten directly. Chlorella food must be cultivated in a clean environment through professional manufacturers. Thirdly, the cell wall of Chlorella has three layers, and it can only be completely digested and absorbed after the digestibility of the cell wall is broken. If you eat wild green algae, you can't digest and absorb it, it's equal to eating it for nothing!
7. Chlorella tablets must be packaged away from light. Chlorella is very sensitive to light because it contains a lot of chlorophyll. Bottled packaging is not as good as aluminum-platinum packaging.
8. If some manufacturers still emphasize the wall-breaking technology, it is a fool. The wall-breaking technology really belongs to a new technology decades ago. After wall-breaking treatment, the digestion and absorption rate of protein in food will be greatly improved. This is why Chlorella appeared in the mainland market so late. The current wall-breaking technology is no longer a sophisticated technology, and many manufacturers can do it. On the contrary, ultra-clean technology and pollution-free production technology are the important factors that determine the quality of Chlorella, which is also the reason why the quality of Chlorella products produced in China is not high (because the water body is polluted and the products are impure).
9. If you claim to import Chlorella tablet products, it is best to show the import hygiene certificate of each batch. The products that can produce the hygiene certificate indicate that the quality of this batch of products is qualified, because this certificate will be issued only after they have passed a series of inspections by the third-party commodity inspection in China, including heavy metal carcinogens, Escherichia coli, nutrients and so on. This is particularly important, and it is also the most important proof to evaluate the quality of Chlorella. Because China has very strict control over imported food internationally. If you can't produce the certificate, the source and quality of the product can't be guaranteed.
10. Bar code problem of imported products. Please don't use irregular software to scan bar codes, because some software, including WeChat code scanning information, is incomplete. Then how to inquire? Search "China Item Coding Center", www.ancc.org.cn. This is the official authoritative website for bar code inquiry in China. Click "barcode information inquiry" on the home page, then click "foreign barcode information inquiry", select "manufacturer information" and enter the barcode. For example, the bar code of the green algae in Green Xianyou is "4711245650016". The result after clicking "Query" is shown in the following figure. Enterprise name: Taiwan Province Chlorella Manufacturing Co., Ltd. (Taiwan Province Green Algae Industry Co., Ltd.).
1 1, taste, color, appearance and other series can refer to the following detailed description. A good Chlorella slice tastes good when chewed, has strong viscosity, strong algae flavor, does not change blindly, and has no other peculiar smell. The color is dark green, the particle surface is soft and uniform, and there are no impurity spots. If the surface is rough, black or yellow due to impure or mixed with other algae and additives, the yellowing is due to product oxidation. If it tastes sour and bitter, it must be microcystins derived from water pollution in the process of farming, and the harm of microcystins even exceeds the harm of heavy metals. Good Chlorella products smell like fresh hay. If there is pungent or fishy smell, it may be mixed with unclean cyanobacteria. The quality of such Chlorella products is really flattering. The main function of Chlorella itself is to detoxify and purify the body. If Chlorella itself is impure, it will not only reduce this function, but even produce side effects. Therefore, if the production conditions and technology are not ideal, there is no nutritional value.
12. Crush the good Chlorella product into powder, and after adding clear water, you can see that the water quality is still clear after precipitation (as shown in the following figure). If the water quality is turbid, it means that the product is unclean and polluted in the production process.
13. A good Chlorella product will oxidize, turn yellow and then turn white within 24 hours after being exposed to air. If the color changes slightly or does not change color, it means that the quality is not pure after adding pigment or other additives.
14, Chlorella is not a special resource, but a freshwater unicellular algae. Chlorella widely lives in fresh water. As long as there are strict production control, advanced technology, suitable temperature, sufficient sunshine, clean fresh water resources and excellent algae species selection and cultivation experience, it can be produced and sold on a large scale. Therefore, there is no patent that Chlorella is only taken away by a few people, and there is no saying that Chlorella can only be produced by applying to state organs. Chlorella has a history of more than 50 years in Taiwan Province Province and Japan, and its popularization rate is also very high. Chlorella has not been widely studied and produced in mainland China for many years because of the imperfect production technology. However, large-scale research, development and production began in Taiwan Province Province in the 1960s, because Taiwan Province Province is rich in fresh water resources, suitable in temperature and good in environment, which is a natural good place for Chlorella production. 70% of the global green algae production comes from Taiwan Province Province, and the market share of Chlorella products in Taiwan Province Province has always been the first in the world. Moreover, most of the green algae in the Japanese market are imported from Taiwan Province Province, because there are two cold seasons in Japan, and the temperature can not meet the conditions for cultivating Chlorella. The suitable temperature for Chlorella culture is about 22-25 degrees. In order to ensure normal sales in the Japanese market, we have to rely on imports from Taiwan Province Province. In particular, Taiwan Province Green Algae Industry Co., Ltd., a leading factory in Taiwan Province Province in the 1960s, has enjoyed a worldwide reputation for 50 years.
To sum up, if you want to produce high-quality Chlorella, you need core technical support such as wall-breaking treatment, clean culture and ultra-clean processing, which is not as simple as most people think, but the combination of years of breeding experience and scientific and technological production results can provide you with high-quality Chlorella products. Chlorella, for example, has a strong function of adsorbing heavy metals and toxins, so purification technology is the core of its production, which requires a lot of investment to complete, which is not available in general production, otherwise it will have been polluted in the process of breeding.
