2. Quality: The reason why propolis has such magical effects depends on various complex components of propolis, and many active components are easily lost in the purification process of propolis. If all the effective components of propolis cannot be preserved, its multiple effects cannot be guaranteed. The identification of active ingredients in propolis can only be observed through the detection of high-precision instruments, so ordinary consumers only need to carefully check the approval function of the Ministry of Health. Propolis has three recognized functions in China: regulating blood fat, regulating blood sugar and regulating immunity. At present, most propolis on the market has one or two functions, and only a few propolis can have these three functions at the same time. Such propolis is the most precious.
3. Is the content of flavonoids in propolis as high as possible? Many people think that the higher the content of flavonoids in propolis, the better, but it is not. First, the reason why propolis can have multiple functions at the same time depends on the comprehensive effects of its precious components, not just the effects of flavonoids. Secondly, the content of flavonoids in propolis refers to the types of flavonoids, not the content of a certain flavonoid. For example, the content of some flavonoids in hay, pollen or other yellow substances is much higher than that of propolis, but its medicinal and health care value is far from that of propolis. As long as the flavone content is not less than 1.5mg/ 1ooml, it belongs to pure propolis. At present, there are some propolis with very high flavone content on the market. We have tested it with professional instruments, and found that it is all inferior propolis made of poplar bud gum, or flavonoids, such as rutin, are artificially added to propolis (only 90 yuan per kilogram).
Is 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. Judging from the market supply price of propolis raw materials this year, the retail price of propolis ethanol extract per 100ml will not be lower than 165.00 yuan.
5. Is there a big difference between imported propolis and domestic propolis? The use value of propolis depends on the plants collected by bees and the extraction process of propolis. China has a vast territory, rich resources and a wide variety of plants, and the content of various effective components in domestic propolis is very high. In terms of extraction technology, the low-temperature countercurrent extraction technology in the National Ninth Five-Year Plan key project of propolis is an internationally recognized advanced technology, so the domestic propolis has completely reached the international standard, and even is in a leading position in some aspects. China is a big producer and exporter of propolis. In western countries, because of the large demand and limited output, it is rarely exported, even if the export price is high. It is understood that the price of genuine imported propolis products is 7-8 times of the same quality in China (of course, those domestic propolis under the banner of import are not within the scope of investigation).
Finally, we call on those propolis enterprises whose production environment and technology are not up to standard to improve the production environment as soon as possible, introduce high technology, and don't cheat consumers under the banner of playing tiger skin.
In short, buying propolis depends on "batch number", "efficacy" and "enterprise".
