1, safety: the original propolis contains lead, arsenic and other heavy metals, can not be consumed directly, must go through the high-tech extraction equipment to remove these heavy metals, and after the national level of the inspection department to pass the test, can be used only when purchased to see whether the product has the "State Ministry of Health Approval Number".
2, quality: propolis has such a miraculous effect, depending on a variety of complex components of propolis, propolis in the purification process there are many active ingredients are very easy to lose. If the active ingredients of propolis can not all be retained, its multiple effects can not be guaranteed. The identification of the active ingredients in propolis can only be observed through high-precision instrumentation, so the average consumer only needs to carefully check the Ministry of Health's approval of its function. China's approved function of propolis has three: regulation of blood lipids, regulation of blood sugar, regulation of immunity, most of the propolis on the market with one or two of these functions, only a few propolis can have the three functions at the same time, so that the propolis is the most precious.
3, propolis in the flavonoid content is not the higher the better? Many people believe that the higher the flavonoid content of propolis, the better, in fact, not. First, the reason why propolis is able to have a variety of effects at the same time, is to rely on a variety of precious components of its comprehensive role, not only the role of flavonoids. Secondly, the flavonoid content of propolis refers to the number of flavonoid compounds, not the high or low content of a particular flavonoid. For example, hay, pollen or other yellow substances in a certain flavonoid content is much higher than propolis, but their medicinal and health care value and propolis is far from it. Flavonoid content as long as not less than 1.5mg/1ooml are pure propolis. Currently on the market there are some very high flavonoid content of propolis, we tested through professional instruments, and found that all are made of inferior propolis by the Yangtse tree buds gum, or in the propolis artificially added flavonoids, such as rutin, etc. (only 90 yuan per kilogram).
4, choose propolis is not the lower the price the better? For consumers, of course, the cheaper the better, but to grasp a scale, after all, the quality of propolis is the most important, from this year's supply price of propolis raw materials market, the ethanol extract of propolis per 100ml, the market retail price will not be less than 165.00 yuan RMB.
5, imported and domestic propolis difference? The value of propolis depends on the plants collected by the bees and propolis extraction process, China's vast territory, a wide variety of plant species, domestic propolis in a variety of active ingredients in the content is very high; in terms of extraction technology, the "Ninth Five-Year Plan" key research propolis project "in the low-temperature countercurrent extraction technology, is currently recognized as the international advanced technology, so the domestic propolis fully meets international standards, so that the propolis is the most important part of the propolis. Therefore, the domestic propolis has fully met the international standards, and even some aspects are in the leading position. China is a big producer and exporter of propolis. In western countries, due to high demand and limited production, it is seldom exported, even if the export price is very high. It is understood that the real foreign imports of propolis products, the price is 7-8 times the domestic equivalent quality (of course, those under the banner of imported domestic propolis, not in the scope of the investigation).
Finally, we call on those propolis companies whose production environments and processes are not up to standard to improve their production environments as soon as possible, and to introduce new and high technologies, so as not to pull up a big banner as a tiger's skin, and to deceive consumers.
All in all, buy propolis to see the "batch number", two see "function", three see "enterprise", you can't do without one!
Bee propolis is a precious substance, known as "human health gold" by scientists. However, propolis products on the market are good and bad, experts remind: buy propolis from the three major factors affecting the quality of propolis and measure the quality of the three major standards to start.
The three major factors affecting the quality of propolis are: differences in bee species, differences in the environment, extraction methods and processing techniques. Firstly, generally speaking, western honey bees are large individuals and produce a high quantity and quality of propolis. Secondly, the important raw material in propolis is the shoots of plants, and plant sources from high latitude and pollution-free zones can create high-quality propolis. In addition, mature propolis development and production techniques affect quality.
The three main criteria for measuring the quality of propolis: First, purity is the guarantee of safety and efficacy. High-tech extraction means, is an important factor affecting the quality and purity of propolis. For example, the counter-current centrifugal technology represents the development direction of propolis extraction technology.
II. Absorbance. The level of absorbance determines the number of flavonoid species and the efficacy of propolis. High-quality propolis, flavonoid species have more than thirty kinds of flavonoids, flavonoid content of more than 15%.
Three, solubility, that is, the solubility of propolis into the body. The high solubility of propolis, fine particles to the nanometer level, into the human body can be fully absorbed by the body, so as to practice the function of the overall conditioning of the human body.
Propolis is also divided into natural and compound propolis, and natural propolis has a good health care effect on the human body.
