Fresh royal jelly is a pure and natural nutritional tonic, and the most valuable thing about fresh royal jelly is its purity and freshness.



Color ---- Generally , fresh royal jelly is usually milk white or light yellow, not easy to flow, shiny and without bubbles. If the color is yellow and lusterless, the royal jelly has been preserved for too long or is of poor quality. If there are dense small bubbles in the royal jelly, the royal jelly has been fermented and the active enzymes have decomposed, losing its nutritional value. If there are ice crystals in the royal jelly, it means that the royal jelly has too much water and is of low value.



Odor ---- Fresh royal jelly has a characteristic aroma, but it is never allowed to have a milky, sweet or tasteless taste. If any of these flavors appear, it means that the royal jelly is no longer fresh or has been adulterated with other substances.


Taste ---- fresh royal jelly tastes in the mouth and feels first sour, then astringent, while there is a hot spicy feeling in the throat. If you feel a little bitterness immediately after tasting, it proves that the royal jelly is no longer fresh.


The authenticity of royal jelly determines the royal jelly effect of we use, while the freshness and purity of royal jelly ensure its activity. it can easily deteriorate if not properly preserved, The existence of this unfavorable factor discourages many people from buying royal jelly.

Cold storage is most important

Freshly bought royal jelly can be kept at room temperature for about 3 days if no measures are taken. If you freeze it in the refrigerator and adjust the temperature to -18℃, the royal jelly can be kept for 2 years or even longer without deterioration, and there are scientific experiments to prove that the royal jelly kept at room temperature cannot make the larvae develop into queen bees, and its nutritional value is extremely low.



Therefore, fresh royal jelly under freezing will not deteriorate and its nutritional value is very high, so why does it prefer cold environment? This is because it is a highly active natural substance itself, sensitive to external factors such as air, water vapor, light and heat, and its physical properties, chemical composition and quality will change significantly at room temperature, reducing the health and tonic function of royal jelly. Therefore, to keep it active and stable, it must be kept frozen and protected from light.
