Is there any saying about the color of propolis that can distinguish good from bad

Propolis. The basic color is brownish-yellow and brownish-red, and the color of its extracts and solutions varies from dark or light due to the different origins, different tree species, different seasons and different concentrations of its solutions. In general, good.

Zhibeetang Propolis.

Its color is brown chestnut or dark brown, whether it is slightly darker or lighter, and when it is poured out of the container, its waterfall liquid surface should be more translucent or darker or lighter.

Amber. A normal propolis solution should not be pure black, nor is it always better to be darker. In general, you can't tell the difference between good and bad just by looking at the color.

The appearance of the propolis capsule is untidy, there are adhesion, deformation, and cracking, and the odor must be inferior propolis.

High-quality propolis is generally yellow-green or yellow-brown and translucent, with an aromatic smell and a slightly spicy taste. However, the quality of propolis products can only be evaluated from the color and sensory indicators of the product. It is important to look at the ingredients of the product.

Hello! 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.

Mine, are you still satisfied?

The softgel is stuck with the index finger and thumb to observe the soft capsule against the bright light, brownish-yellow, brown-red, and transparent color, the concentration is low, and the propolis content is correspondingly low; The concentration of blackening and opaque is high, and the content of propolis is correspondingly high.

How to tell the difference between propolis and propolis.

Appearance. According to the common sense of life, we all know that the first thing to look at is its appearance, and propolis is no exception, high-quality propolis is opaque, high concentration, solid, smooth surface, and no impurities. Some inferior products have debris, wood chips, hemp silk, or other impurities on the surface, with small concentration and liquid form.

There are also mixed with sediment, this kind of propolis is not recommended for everyone to buy, it contains many bacteria, and eating too much will affect health. High-quality propolis will precipitate out of the polyethylene glycol solution when mixed with warm water, forming tiny propolis particles that are suspended on the surface of the water and look like an emulsion. Most of the inferior propolis is made of inferior propolis, beeswax, gum, etc., which are made of artificial flavonoids, which will form a solid form when dropped into warm water, which is not easy to dissolve, and eating it is harmful to the body and digestive system.

Specifically, we can see in the figure below).

Comparison of propolis drops in warm water.

Fragrance. Next, we are talking about the fragrance of propolis, natural propolis has an aroma, similar to floral, the taste is better but not pungent, and when burned, it will emit a precious resin aroma, similar to frankincense. The poor quality, the fragrance is stronger, and you will feel a little tired after smelling it for a long time, and some adulterated propolis on the market will smell like a flavor, and there will be a burnt smell when burning.

Color. What color is propolis in everyone's impression? Here I would like to tell you that the natural high-quality propolis is brownish-yellow, tan or grayish-brown, sometimes with a little turquoise, and a few propolis is close to black.

Since propolis is produced in many regions of China, the difference in climate and other conditions in these regions has caused differences in the color of propolis. Inferior propolis is light in color due to impurity or the addition of other substances, generally pale yellow, some pale red or pure black.

Purity. When buying honey, everyone knows to look at its purity, and the same is true for propolis. Natural propolis is naturally extracted and has high purity. The content of propolis in inferior products is small, and it may be adulterated with other substances, or the content of harmful substances exceeds the standard, and the purity is low.

**。Do you know? Propolis is called purple**, the yield is only one-eighth of the yield, the propolis that is too cheap on the market is very likely to be fake propolis or inferior propolis, and the health indicators of inferior propolis do not meet the national testing standards, so it is generally low.

When purchasing, we must be careful not to fall into the trap of "**low".

Precautions. For propolis, the longer the time, the better the effect. When we buy, we should choose some propolis brands with good reputation, fixed ** points and long sales time. Only products with good effect and good quality can gain a foothold in the market for many years.

1. The fidelity of propolis raw materials can ensure the fidelity of propolis products.

Because: propolis is made from raw materials after the finished propolis is not easy to identify, so when consumers choose propolis products, they mainly look at whether the manufacturer has enough raw materials, and remind consumers not to buy propolis produced by enterprises without raw material reserves.

Note: It is difficult to check the raw materials of propolis products processed on behalf of others. Zhibeetang has the largest propolis bank in Asia.

2. Good purification technology can ensure good effect and less impurities.

Because: propolis has more than 300 kinds of active ingredients, and there are also impurities and heavy metal residues, if the purification technology is not suitable, it is easy to cause the loss of propolis active ingredients, and heavy metals exceed the standard.

Note: Zhibeetang has a patented technology for purifying propolis, which can ensure that the active ingredients are not lost, and the heavy metal content is at least ten times lower than the national standard. Zhibeetang propolis is also one of the few propolis approved for the three functions of regulating blood sugar, immune regulation, and regulating blood lipids at the same time.

2010-11-25China Journal of Traditional Chinese Medicine also confirmed that only propolis with these three functions is a good propolis.

3. The long time of existence, the quality of the product is more advanced.

Because: only long-term inspection by consumers can confirm that the product has good effect and high safety.

Note: Zhibeetang propolis has been on the market for 16 years and is one of the first batch of approved propolis production enterprises in the country.

4. Advanced production technology, excellent production environment, and approval by the national quality supervision department are also important indicators for judging the quality of propolis.

P.S. 1: What is fake glue?

Fake propolis is often processed from poplar leaves, old nest spleen, etc., and lacks natural propolis. The aromatic smell, the texture is very brittle, and there is no toughness, and the iodine value and saponification value are low in chemical testing. Fake propolis also includes adulterated propolis, such as gum, cottonseed cake, rapeseed cake, old nest spleen, etc.

P.S. 2: What is a low-quality propolis product?

Inferior propolis products refer to propolis products with low active ingredient content, unqualified health indicators, substandard physical and chemical indicators, and serious excessive content of impurities and harmful substances.

The characteristics of low-quality propolis products are:

The actual content is much lower than the claimed level. For example, if the claimed content of pure propolis is 20%, the actual test result may only be 10% or even lower.

The production conditions of the product are poor, the health indicators and physical and chemical indicators do not meet the requirements, and the content of some heavy metal lead is as high as 10mg kg;

Products are sold at low prices. Propolis is called purple**, and the yield is only one-eighth of the yield, and too cheap propolis is often fake propolis or low-quality propolis, such as: adding other ingredients, adding thickeners to extract, etc.

The appearance is opaque, solid, the surface is smooth or rough, the fracture surface is sandy, and the cut surface is similar to the shape of marble. For better quality propolis, bee body limbs, sawdust, hemp silk and other inclusions should not be found by the eye.

The color is yellowish-brown, brown or grayish-brown, sometimes tinged with a greenish tinge, and a few darker ones are similar to black.

The fragrance has a lovely aromatic smell and emits an aromatic smell of precious resin when burned. Taste the slightly bitter taste with your tongue.

The stickiness is sticky and can be softened by rubbing it with your hands. When the temperature is at 36, the propolis is soft, sticky and malleable when stirred with a small stick. When the temperature is below 15, propolis becomes hard, brittle, and easily crushed. At a temperature of 60 to 70, the propolis melts and separates the beeswax.

The density density is larger, generally kilogram liters, and usually the density is around kilogram liters. Artificially adulterated with beeswax or paraffin reduces the density of propolis.

Purity: Propolis dissolved in 95% ethanol should be a transparent maroon solution, pure propolis can only find granular insolubles, there should be no other impurities. Propolis mixed with spleen wax blocks can be seen in ethanol with insoluble aggregates.

2) Physical and chemical indicators.

China's propolis acquisition department usually classifies according to the content of propolis ethanol extract: accurately weigh the propolis powder gram in the mortar, grind it into a paste with 25 ml of ethanol and transfer it into a frosted cap jar, cold soak for 24 hours, filter it with a weighed filter paper, and then wash the insoluble substance twice with a small amount of ethanol, and weigh the insoluble substance together with the filter paper after 45 drying, and calculate the percentage content of propolis ethanol extract.

The content of propolis ethanol extract is 50% of the foreign product, the content is in the first grade, and the content is the special grade.
