Royal Jelly is classified according to its quality: superior products, first-class products and qualified products. The common quality problems of royal jelly: excessive moisture content; deterioration; adulteration (eg, incorporation of milk, starch, talc, or dairy products, etc.). Since royal jelly is rich in active substances, temperature, air and sunlight have a great influence on the quality of royal jelly. When it is left at room temperature for a day, its freshness is significantly reduced. Therefore, when pure royal jelly is purchased, its product should be sealed and sold in a cool, dry place.

Excellent products were milky white, with a clear glossy sensation; first-class products were light yellow and shiny; qualified products were yellow-red, poor luster. Royal jelly has a pale or very bright color, indicating that royal jelly is mixed with milk, honey and so on. If the color becomes darker, there are small bubbles, mainly due to poor storage, long-term air, resulting in quality spoilage. Matte royal jelly is inferior. Look at the state: royal jelly has a slurry, translucent, slightly sticky, no larvae, wax and other impurities, no foam (fermentation signs). The superior product is in a paste-like shape, slightly sticky, glossy, without larvae, wax and other impurities, no bubbles. True royal jelly, moderate consistency, creamy. If the consistency is lean, it indicates that there is much moisture, or it is mixed with falsification; if the consistency is thick, it means that the slushing time is too late or stored improperly. Smell smell: royal jelly has a unique alcohol, acid aroma, pure smell, the stronger the aroma, the better the quality. Excellent product royal jelly aroma, pure gas; first-class royal jelly to look at light, pure gas; qualified products have royal jelly aroma, pure gas. Truly royal jelly, microstrip floral aromas, and unscented are fakes. If there is fermented taste and bubbles, it indicates that royal jelly has been fermented and deteriorated. If royal jelly has a hazel taste, it means rancidity. Such as adding milk powder, corn flour, malted milk, etc., there is milky or tasteless.

At the same time, the single pollen variety is an important indicator of the pollen quality grade. The method of sensory detection is to randomly select 100 bee pollen grains. The number of pollen grains with the same number of colors is divided by 100, which is the percentage of single pollen clusters for flowering. The higher the single pollen rate is, the higher the pollen purity is. Smell smell: The fresh bee pollen has a strong natural scent, and the mildewed bee pollen has no scent or an unpleasant odor. Excellent products have a distinct fragrance of single flowers; first-grade products have a single fragrance of flowers; qualified products have aroma of pollen.
