Best Raw Natural Propolis Of Manufacturer Crude Propolis Price Crude Propolis

Natural Raw propolis lead question

Propolis in raw materials, the main reason for the lead and other heavy metal exceeds bid is due to the propolis using wire gauze in bee production vice cover,; Starting in 1920, after three generations of beekeeping family, as early as 1990, BaiChun biotechnology ferula acquisition method has been adopted to collect the original propolis, raw materials such as lead in heavy metal exceeds bid has been largely put an end to.

The extraction methods of health raw propolis

Experiments prove that: using ethanol as solvent purified health raw propolis, is the best effect of purification methods, use the method to extract propolis all the indexes can meet the standard requirements, some comprehensive to preserve its effective ingredients, extract the antibacterial effect is best. Food safety indicators also meets the requirements, it is a practical and efficient extraction method.

"Supercritical extraction technology", is the current chemical extraction technology than some of the advanced technology, some people take this hype. Actually, propolis with "supercritical extraction technology to extract", it is not very scientific, supercritical fluid extraction "due to the influence of temperature and pressure, can extract similar molecular structure of the material, as a result of propolis contains material is very complex, there are dozens of flavonoids, light, therefore, the supercritical fluid extraction can only part of the extracted propolis material, such as the main function of propolis substance, flavonoids, only around 20% of ethanol extract, in addition, the extracted material also is not propolis. And because of its expensive, in fact, now including the hype "supercritical extraction technology" enterprise, no firm has purified propolis by this method as a commodity to sell, therefore, is purely commercial hype.

Recently, there are companies in the hype "water-soluble propolis", in fact, this also want after purification with ethanol, to join in propolis emulsifier (at most is to join twain, 80), after adding additive, have an effect on food safety, the experiments have proved that propolis after joining emulsifier "water-soluble propolis", its function, antimicrobial properties close to zero. And, using ethanol as the solvent of propolis products, the body can not absorb the same, just the water-soluble propolis may slightly on the edible convenience. As a result, the main function of this at the expense of propolis and security at the expense of edible is convenient, is a violation of science, is debatable. BaiChun -  health raw propolis/ health raw propolis/ health raw propolis.

The so-called "water-soluble propolis" without emulsifier, actually have a plenty of added sodium hydroxide, this is banned in food.
