How to distinguish the authenticity of royal jelly, how to identify the authenticity of royal jelly

Royal jelly is bee milk, which is a light yellow or milky white thick pulp secreted by worker bees from the palate glands, with a very complex chemical composition and contains a variety of amino acids, glycases, esters, B vitamins, pantothenic acid, folic acid, inositol, acetylcholine and"10-hydroxy-2-carboxaenoic acid", as well as some unknown substances that may preserve fertility and longevity, is a high-grade tonic.

The quality identification method is as follows:

1) Look closely at the appearance, the high-quality product is a light yellow or milky white gelatinous liquid with gloss and soft particles.

2) Smell it with a clear fragrance, rub it with your fingers and have a delicate feeling, and it is not rough and sticky for high-quality royal jelly.

3) The color is gray, dark yellow, pink or brown, etc., which are not of the highest grade.

4) Tilt the container, if bubbles bubble from the royal jelly, indicating that it has gone bad and cannot be purchased.

5) If the royal jelly is too thin, it may be mixed with water; If it is too thick, the essence slurry may have been removed and the nutritional value has been reduced.

6) Insert the slurry with a glass rod and then pull it out, if there is a hanging rod phenomenon, it indicates that it may be mixed with impurities.

7) Take a little taste of the mouth, such as sweet, sour and astringent, for **; If it is too sweet, it may be mixed with sugar and honey; Too much acid is a sign that it may have spoiled.

Precautions] Royal jelly can not be taken with boiling water or tea, because the temperature is too high and easy to destroy its active substance, and the tannic acid and iron in the tea will reduce its efficacy. Another point is that it must be taken for a long time to be effective.

To identify the authenticity of royal jelly, first pay attention to the temperature of royal jelly. Authentic royal jelly is kept at a constant temperature after harvesting, usually around 35 degrees Celsius, which is similar to the temperature inside the hive. Therefore, if you buy royal jelly with a temperature significantly lower than 35 degrees Celsius, it may be a fake.

Observe the color and texture of royal jelly. Real royal jelly is milky white or yellowish in color and has a dense and silky texture. If royal jelly is dark yellow or grainy, it may have been adulterated with other substances or added pigments.

Smelling the smell of royal jelly is also a criterion. Authentic royal jelly has a faint floral scent, fresh and natural. If it smells bad or doesn't smell anything, it's probably a counterfeit product.

In addition to these methods of direct observation, we can also distinguish the authenticity of royal jelly by purchase channel and brand reputation. It is recommended to choose a reliable and reputable merchant to buy, and pay attention to whether the packaging of the product is formal and whether there is a relevant certification mark.

The ** of royal jelly is also a reference factor. Authentic royal jelly is usually higher due to its difficulty in harvesting and low yield. If a product** is significantly lower than the market average, there may be an issue of authenticity.

To distinguish the authenticity of royal jelly, it is necessary to comprehensively consider the temperature, color, texture, smell and other aspects, and combine the purchase channel and other factors to judge. Try to choose a reliable merchant to buy, and pay attention to the packaging and certification marks of the product. If you are still unsure, you can consult a professional or seek confirmation from a relevant authority.

Remember, it's important to choose authentic royal jelly for health and safety.

Fresh royal jelly has a good gloss, with milky white and pale yellow as well, and only a few royal jelly are affected by the nectar source plants, such as buckwheat, mountain pepper, and eucalyptus produced during the flowering period of royal jelly is reddish. In general, the color of royal jelly will be due to too long storage, improper storage methods, contamination and other reasons.

Because royal jelly has high nourishing and medicinal value, it is expensive, so some people have used corn flour, milk powder and other adulterated counterfeits to harm the masses. The methods of identifying the authenticity of royal jelly are introduced as follows:

Genuine Royal Jelly: Milky white or yellowish translucent slurry semi-fluid. The smell has a special sour smell, the tongue tastes sour first and then astringent, and the pH value is between 3 5 4 5. The test of pure iodine solution is reddish-brown for **.

Fake and inferior royal jelly: If there are a small number of bubbles on the surface of royal jelly or the color is light, it means that there are bacteria breeding and fermenting; If the color is light and thin, it proves that the water content is high; If the slurry is thick and there is paste, it indicates that there is counterfeit adulteration; If there is a rotten smell, it means that it has deteriorated; If it has a milky taste or no taste, it may be adulterated with counterfeit products, perhaps milk powder, malt milk powder, corn flour, etc. If you taste sweetness with your tongue, it is a counterfeit.

If it is tested with iodine solution, if it is mixed with starchy substances, it will turn blue when it encounters iodine.

How to choose royal jelly? First of all, be sure to read the instructions on the package. It is necessary to label the protein content of not less than 30%, and the content of royal jelly acid not less than 4%.

Second, it depends on whether the enterprise producing royal jelly has a beekeeping base. Royal jelly is very delicate, and it is difficult to guarantee the quality of royal jelly purchased from the market by enterprises without beekeeping bases. Third, it depends on whether it is a professional bee product company.

The production process of royal jelly freeze-dried powder is very strict, and the quality of the enterprises that have just joined the production of royal jelly freeze-dried powder is unstable. Fourth, it is necessary to look at the level of scientific and technological content of the enterprise, and the status of the domestic and international bee products industry. Fifth, enterprises with high market share and large market share, the efficacy of royal jelly has been recognized by the majority of consumers.

Sales identification. For the finished royal jelly sold on the market, it is difficult to say due to the variety of dosage forms. Generally speaking, as an ordinary consumer, you can be screened from the following aspects:

First, the raw materials of the product. China is the world's highest production and most exported royal jelly production area, and the quality of royal jelly is the best product in Qinghai Qinghai-Tibet Plateau, and the acid content of royal jelly is the highest in the world.

Second, look at the origin and manufacturer. Good manufacturers will keep the royal jelly fresh in time, so that the nutrition of the royal jelly can be better preserved when the royal jelly reaches the hands of consumers.

Third, look at Chinese or international approvals. This is the **control aspect.

You should choose a regular store or bee product store with three certificates (business license, health permit, tax registration certificate) to ensure product quality. Remember not to buy three no royal jelly (no factory name, factory address, trademark, no approval number, no production date).

Quality experiments. The first is the identification of royal jelly products with starch: one to two drops of iodine wine are dropped into the experimental royal jelly products, and the pure royal jelly products are light yellow or orange-yellow after iodine, and the royal jelly products mixed with starch become blue or purple when they meet iodine;

The second is the identification of royal jelly mixed with dairy products: the experimental product and a few drops of edible alkali are stirred at room temperature, if the suspended solids are all dissolved and light yellow transparent, it means that the sample is pure royal jelly, if it is not dissolved and turbid, it means that the sample is mixed with dairy products.

Countries around the world have different quality requirements for royal jelly. For example, Japan focuses on judging the quality of royal jelly by the content of royal jelly acid (10 HDA); European and American countries focus on sensory indicators and moisture. 10 HDA is indeed an important ingredient of royal jelly, which can be used to measure the authenticity of royal jelly; However, the nature of 10 HDA is stable, and even if the royal jelly has deteriorated, its 10 HDA content has hardly changed.

Therefore, it is one-sided and unscientific to measure the quality of royal jelly at the content of 10 HDA. The content of royal jelly in China is above 10 HDA. Superior royal jelly is milky white in color, with obvious luster, no impurities, bubbles, strong aroma, positive smell, obvious sourness, spicy, slightly sweet aftertaste, and moisture.

How to identify the authenticity of royal jelly? Royal jelly is very common in the market, and because it is common, there are lies in many places, so it is extremely important for friends who often eat royal jelly to know the truth of royal jelly. Because no one wants the hard-earned royal jelly to be a counterfeit product that harms health.

So in the future, I will introduce how to identify the authenticity of royal jelly.

1. Market sales identification

As for the finished royal jelly sold on the market, it is difficult to say because of the variety of types. But generally speaking, as an ordinary consumer, it can be identified from the following aspects:

Clause.

First, the raw materials of the product. China is the world's highest production of royal jelly, but also the most exported royal jelly, and the quality of royal jelly in Qinghai, Qinghai-Tibet Plateau as the best products, this origin of royal jelly acid content is the highest in the world.

Clause.

Second, look at the origin and manufacturer. A good manufacturer can keep the royal jelly fresh in time, so that when the royal jelly reaches the hands of large consumers, the nutrition of the royal jelly can also be better preserved.

Clause.

Third, look at China or international approvals. This is controlling.

2. At present, there are two types of adulteration of fresh royal jelly, which are the most common ones:

1. Identification of milk powder and other starch royal jelly:Starch will turn blue when exposed to iodine, starch can become dextrin after hydrolysis, and dextrin will turn purple when exposed to iodine. Pure royal jelly is light yellow or orange-yellow when exposed to iodine.

Easy method: Take a drop of royal jelly and drop it on the paper, wait for a period of time, if there are traces of water seeping, it means that the royal jelly is adulterated.

2. Identification of royal jelly in dairy productsA small amount of alkaline noodles or a few drops of 20% NaOH are stirred at room temperature, if the suspended solids are all dissolved and light yellow transparent, it means that the sample is pure royal jelly, if it is not dissolved, and it is turbid, it means that the sample royal jelly is mixed with dairy products.

3. The choice of color

The color of fresh royal jelly is milky white to pale yellow, and some are reddish, and the color of royal jelly mainly depends on the source of the honey powder and its freshness and quality.

1) The pollen color of the pollen source plants in the pulping period is heavy, such as buckwheat and mountain peppercorn, and the pollen color is darker, so the royal jelly produced is reddish; The light pink of rape, black locust, vitex and other honey sources, the color of the royal jelly produced during the period is milky white or light yellow.

2) Improper storage method of royal jelly or too long storage time, and improper processing method caused pollution, or fresh royal jelly mixed with counterfeit products has a darker color, and vice versa.

How to identify the authenticity of royal jelly? I believe that through the detailed introduction above, we also have a certain ability to distinguish the authenticity of royal jelly, so when you go to the market to buy royal jelly, you must make the right choice, so as not to buy the royal jelly you worked hard to buy is a fake and shoddy product, if you eat it, it is extremely bad for your health.

01 The smell of royal jelly.

If you smell the smell of royal jelly, if it emits a sweet smell of pollen, it means that the honey is real, and if it smells hot and sour, it means that the honey is fake.

02 The taste of royal jelly.

Taste the taste of royal jelly, which is different from other honeys, common honey is sweet, while royal jelly is slightly bitter, so if it tastes sweet, it means that it is a fake royal jelly.

03 The state of royal jelly.

The color of royal jelly is generally milky white or milky yellow, and it is generally pulpy, not very thin, so if the honey is very thin, it means that it is fake royal jelly.

04 Rub it off.

Take out a small amount of royal jelly in the palm of your hand, and then rub it with your hands, if it is very viscous, it means that it is real royal jelly, otherwise it is fake royal jelly.

To distinguish between real and fake royal jelly, you should be able to accompany the spine to see, smell it, knead it three times, and taste it four times when purchasing. At first glance, the high-quality fresh royal jelly is delicate and smooth, with a milky white or pale yellow surface and a shiny finish.

For the identification of royal jelly products with starch, one or two drops of iodine were added to the experimental royal jelly products. Pure royal jelly products are light yellow or orange-yellow when exposed to iodine, and royal jelly products mixed with starch turn blue or purple when exposed to iodine.

For the identification of royal jelly mixed with dairy products, the experimental product was stirred with a few drops of edible alkali at room temperature. If all the suspended solids are dissolved and appear light yellow and transparent, it means that the sample is pure royal jelly. If it is not dissolved and is turbid, it means that the sample royal jelly is mixed with dairy products.

Distinguish the real from the fake

With the improvement of living standards, people's demand for nutritional products has gradually increased. Especially in recent years, royal jelly has gradually entered people's field of vision. Royal jelly is a natural, high-quality nutritional supplement that can be consumed by both young and old.

But the most dreaded thing to encounter when buying something is to buy a fake, and this situation is often encountered when buying royal jelly.

This is because the production conditions of royal jelly are very harsh, and it is difficult for laymen to distinguish the real from the fake through the appearance of stupidity, so there is a lot of room for fraud. Authentic royal jelly is generally pale yellow or milky white in color, and will be very bright in the sun. And there is no obvious color difference in the bottle, while the color of inferior royal jelly will be slightly darker, and obvious bubbles can be seen after shaking.
