Is the fresh royal jelly in China good? It is best to eat royal jelly capsules from New Zealand.

The characteristics of high-quality royal jelly: first, put a little royal jelly into a colorless and transparent glass tube, which is milky white or light yellow, and the overall color is consistent. Secondly, it can be observed that there are colloidal particles in the pulp, which have a certain luster and viscosity like cream. Thirdly, there is a special fragrant smell, which tastes sour, astringent, slightly sweet and spicy, but not too much. Too sour may deteriorate, too sweet may be mixed with honey or sugar, and insufficient astringency may be adulterated. The pure product was detected by iodine solution and was reddish brown.

Inferior royal jelly is characterized by dark and gloomy color, too thin and too thick consistency, some pulp in a bubble state, and no flowers on the surface of the pulp (except the sucked royal jelly). When you pinch it with your hands, it feels rough and sticky, smelly or rotten, and it tastes too sour, too sweet or too astringent.

Adulterated royal jelly

(1) detection of dextrin and synthetic pulp essence: chopsticks are inserted into the pulp and pulled out to form filaments, which are sticky, while pure royal jelly is not easy to form filaments.

(2) Detection of pollen balls and corn flour: you can feel lumps when you pinch them with your hands. Putting these particles on glass and baking them in alcohol will not dissolve, indicating that there are substances similar to pollen balls and corn flour mixed in them.

(3) Detection of honey and sucrose:

Take a little and taste it on the tongue, which can obviously feel the sweetness. Chemical determination of sugar content can also indicate that low-grade carbohydrate substances are mixed. Normal royal jelly contains 20% reducing sugar.

(4) Detection of dairy products: Take a little royal jelly, add appropriate amount of water to boil, add a little salt after cooling, and flocculent precipitate appears immediately, indicating that there are dairy products.

(5) Detection of starch: put a little vinegar in royal jelly, and the blue color is royal jelly mixed starch.

False royal jelly

Drop a drop of royal jelly on the filter paper, and then drop a drop of n3minhydrin test solution, and bake it in an oven at 105℃ for 3 minutes, or shake it to dryness above the flame. Real royal jelly can make the spots on the filter paper appear blue-purple, while fake royal jelly has no such specificity. The chemical detection method should detect the unique component of royal jelly-royal jelly acid, which does not exist in other natural substances.

Whether abroad or at home, brands or beekeepers, only high-quality royal jelly can play a good health care role and wish health.
