How to identify propolis and how to identify propolis

I'll say a few key things.

1, look at the outer packaging, I won't say any of this, the upstairs has already said a lot. However, try to buy health food after 2000, and there is a health brand, because the health food before 2000 is too simple when it is approved. It's been exposed to the sun!

2；The preferred softgel softgel is pure in texture, large in content, easily absorbed by the human body and treated with lead removal. Hard capsules have relatively more impurities and a small content, which is not easy to be absorbed by the body and is difficult to remove lead.

Appearance: If the softgel is stuck with the index finger and thumb against the bright light, the brown yellow, brown-red, and transparent color will have a low concentration and a correspondingly low propolis content; The concentration of blackening and opaque is high, and the content of propolis is correspondingly high.

The softgel is bitter and slightly spicy, accompanied by an alcoholic taste. If it is salty, it is likely that soy sauce has been added; For those that are sweet, honey or sugar is added. These two flavors are directly judged to be fakes.

Smelling Propolis Liquid Propolis Liquid has a pleasant aromatic smell.

Pierce the soft capsule with a bowl or cup of water, drop the propolis liquid in the water, it can be seen that it immediately sinks to the low part and does not disperse, and a thin layer of white emulsion floats on the water surface, which immediately becomes white and turbid after stirring, and the one that does not change color is false. If you pour out the water, you can see that there is a propolis residue at the bottom, which is not easy to wash off with water, and it will be true when you wipe it with wine. The one with no residue at the bottom is false.

Propolis has a special fragrance and is slightly spicy.

One is water solubility and impurities, high-quality propolis products should be completely dissolved in water without any impurities; However, it is difficult to dissolve propolis tablets and hard capsules in water, and some cannot be dissolved after soaking in water for 1 month; Most of the soft capsules are not completely dissolved in water and form a paste; Inferior propolis liquid will have many substances sticking to the walls of the cup. This is due to the fact that propolis liquid contains a large amount of beeswax, which can be harmful to the human body.

The second is concentration, color and purity, good propolis should be golden yellow in water, which is the true color of precious flavonoids. The higher the concentration, the higher the propolis content. However, while paying attention to the concentration, it is also necessary to observe the purity of the aqueous solution.

Some propolis is made with substances such as emulsifiers, and the aqueous solution seems to be very concentrated and golden in color, but the purity of the solution is not high, there is a turbidity feeling, and there is often precipitation at the bottom of the cup. If you leave it for a day or two and find that the aqueous solution turns orange, then this indicates that the manufacturer has added emulsifiers and other substances to the propolis liquid.

The third is taste, if through the above observations, no obvious problems with propolis products are found, then the last step is to taste the aqueous solution. Real propolis has a very light bitter taste in the mouth, but it will have a spicy sensation in the throat when swallowed. The more spicy it is, the higher the quality of the propolis.

This is the most critical step in the quality identification of propolis. Almost all propolis products that seem to be of good quality will show their original shape in the process. Defects in most propolis products can be detected through the above steps.

When buying propolis products in the future, you can ask the merchant to put the product in water to make it easier to judge its quality.

When buying propolis, we should know its main characteristics and how to identify it. Pay attention to check whether there is a regular approval number of the national food health character, you can first go to the official ** of the State Food and Drug Administration to find out whether the product has passed the national GMP certification and whether the imported propolis has the "Imported Health Food Approval Certificate"; Authentic propolis drops on the water surface of the glass to form an oil film that is not easy to dissipate, and the gum drops into the water, which will quickly spread to the wall of the cup; Propolis smells aromatic, while gum has a foul odor; Authentic propolis has a large viscosity to the touch, and the viscosity of the gum is obviously insufficient. At the same time, the appearance and color of propolis can also be identified with the eye; Taste with your mouth to identify the taste of propolis; The purity of propolis was determined by dissolving it in 95% alcohol.

Tianbaokang Propolis National Propolis Compilation Group host development, you can go to the official website to understand the situation, ensure quality, and have sales all over the country.

1.Observe the surface of the propolis.

In natural light or under lighting, the texture of real propolis is crystal clear, showing a translucent brown-red color. However, if it is a counterfeit or inferior propolis, it will appear tan, black and opaque.

2.Smell the smell.

Natural propolis generally does not have an unpleasant taste, but will present a faint fragrance; Inferior or counterfeit propolis will have a faint foul smell.

3.Look at the content.

The flavonoid content in propolis is an important criterion for judging the quality of propolis. Propolis has a variety of functions are related to flavonoids, when choosing propolis products, we must pay attention to the content of flavonoids, the normal efficacy of propolis products with low content can not be guaranteed.

1. Visual inspection. When the capsule shell is opened, the contents are yellow-brown, tan or gray-brown for high-quality, high-purity propolis. If it is obviously black, it may be excessive heavy metals or artificially added synthetic flavonoids.

2. Taste. Chew and taste, although good propolis will feel spicy at the moment of chewing and swallowing, it will disappear naturally at once, and a refreshing feeling will follow; Inferior propolis will make people want to vomit after chewing, without spicy.

3. Smell. Good propolis smells like sap, while low-quality propolis has no smell.

4. Absorption. Drop a drop of propolis on a white piece of paper (letter paper or tissue paper) and let it sit for a few minutes to observe its changes

If the diffusion rate is too fast, it means that the content of alcohol or water is too high. If it is not easy to seep, the glue content is higher; Good quality propolis is golden yellow paste after drying, and it is shiny.

5. Dissolve. Prepare half a cup of warm water, add a drop of propolis (not too large) and stir slowly.

It can effectively suspend in water and dissolve into superior products, and cannot be dissolved into inferior products at all.

If it turns from milky white to pale yellow-green when dropped, its quality is better. If the dissolved solution is gray-brown, it is inferior.

The sensory identification of propolis is mainly based on appearance, color, fragrance, odor, viscosity and purity.

Propolis is a precious solid substance, opaque, smooth or rough surface, the fracture surface is sand-grained, the cut surface is similar to the shape of marble, yellow-brown, brown-red or gray-brown, sometimes blue-green, a few are almost black, generally insoluble in water, only a small part of the substance is soluble in water, propolis is soluble in ethanol, acetone and other solutions.

True propolis solid particles have an aromatic odor, when burning, it emits a fragrance similar to frankincense, the taste is slightly bitter, slightly spicy, sticky to the teeth when chewing, can be softened by hand kneading, and begins to soften at 36, its viscosity and plasticity will become hard and brittle when it is less than 15, and can be crushed, and melted into a viscous fluid at 60 70 times, dripped into alcohol, and can be dissolved.

On the market, there are many propolis products, and the products are uneven, how to distinguish a good propolis?

The champion of the National Bee Industry Propolis Sensory Identification Competition, Director Huang of the Purchasing Department of Wang's Bee Garden, introduced five words, as long as you remember it, you can be sharp-eyed and not let inferior propolis fall into your pocket.

1. Smell the smell.

Good propolis has a special aromatic smell, and when burning, it has a resin milk aroma and no peculiar smell.

If propolis is mixed with gum, it has a faint smell.

2. Taste the taste.

The taste of propolis is slightly bitter, slightly astringent, slightly numb and spicy.

If it is a gum, it has no spicy feeling.

3. Look at the label.

Look at whether there is a blue hat, and some are to obtain the national health food production approval; See if the company name is consistent with the manufacturer.

If there is no blue hat, it is not a national health food; If the names are inconsistent.

Fourth, shine on the lights.

Fifth, look at the brand.

Propolis is really difficult to identify, there are a lot of fakes, a few days ago I saw a Sina blog on the Internet called "Propolis Know-it-all", which is done by a bee product researcher, very professional and detailed. You can go there and find the answer you need, so don't forget to give points.

After the pure propolis softgel is punctured, the contents of the propolis are dropped into the glass, and the stirring water quickly turns milky white, and a very small amount of propolis is evenly dispersed at the bottom of the cup; Inferior or fake propolis is dark brown or black in water; Pure propolis has a natural and special fragrance, while inferior or fake propolis-gum has a faint foul smell; A drop of pure propolis on the tip of the tongue will have the unique pungent sensation of propolis, while fake propolis does not; In natural light or light, pure propolis softgels will be observed to have a crystal clear texture and a translucent brownish-red color, while low-quality or fake propolis will be opaque or tan or black.

It is worth choosing and noting: 1. Look at the content of active ingredients and whether there are bad additives; 2. Look at the platform, whether the qualifications are complete, whether there is a traceability mechanism, and the after-sales service is guaranteed.

At present, there are not many pure propolis products on the market, and it is common for propolis products to be mixed with gum. The identification of the active ingredient in propolis can only be observed by the detection of high-precision instruments. It is difficult for the average consumer to tell the difference, so be cautious when buying.

First of all, consumers can smell propolis first, because the aroma of real propolis is very thick, but the smell of gum is not so good; Secondly, taste the taste again, the taste of pure propolis tastes sour and astringent, and is accompanied by a spicy and pungent feeling, and the taste of pure gum is relatively light; Third, look at the color, under natural light or lighting, the texture of pure propolis is crystal clear, showing a translucent brown-red, and the color of the gum is relatively light; If you buy a propolis capsule, you can open the capsule first, squeeze out the contents and put it in 60 to 70 warm boiled water, if it forms a pale yellow emulsion, a little cloudy but does not appear clumpy, it means that the propolis is relatively pure; If there is a more obvious clumping, it is gum.

Propolis is the most common health care product, which has a good effect on diabetes and hyperlipidemia. Eating propolis can remove deposits in the blood, improve blood circulation, and reduce the occurrence of blood clots and cardiovascular diseases. Propolis is better to eat on an empty stomach, it can be taken half an hour before meals, it is best to take it with warm water, it is recommended hereXingyue Bee Brand Propolis SoftgelsThe flavonoid content is higher than the market and the quality is guaranteed, which is not only conducive to the absorption of its components by the gastrointestinal tract, but also makes the effect of propolis better.

You can't tell.

If you can distinguish the authenticity of propolis capsules, the domestic propolis market will not be flooded with fakes Fake propolis made from poplar buds Old beekeepers who have kept bees for many years have a time when they look away, let alone ordinary consumers.

Let's get you a raw glue** for reference.

Upstairs, if you don't understand, don't mislead others, okay, can propolis melt water? It will melt if you pick it yourself, the essence of propolis is not melting, and the fake can also be said to be true, you are a little morally good.

You can't see it with the naked eye, you can only read the instructions, but the things on this package text are inevitably fake, so it's hard to judge whether propolis is good or bad.

Let me remind you that once the flavonoids in propolis are written on the label exceeds 5%, then it is definitely added with chemical flavonoids, which does not mean that it is fake, but that chemical flavonoids damage the human gastric mucosa.

Now the new one called Nandan Propolis is extracted from honey through supercritical carbon dioxide extraction technology, which are natural flavonoids, which are very good for health, and there is nothing to do.
