The article reviewed the foreign and Russian research of the changes in quality of royal jelly (Apis mellifera L.) caused by paratypic factors. The main quality standards of royal jelly are the total content of protein, sugars and 10-HDA concentration. The total protein and 10-HDA content determine the therapeutic properties of royal jelly. In 12 countries standards for royal jelly have been developed, these criteria do not differ much, but in Russia this standard regulates the product with no regard to modern methods of evaluation and quality standard. The quality of royal jelly is influenced by many factors. Honey bees of different breed origin produce royal jelly with different content of total protein and 10-HDA. Dark honey bees produce royal jelly with an average 0.3% higher concentration of protein and 10 - HDA. A negative correlation between the total gain of royal jelly and 10-HDA concentration has been determined (r=-0.77, p≤0.05). The quality of melliferous plants have a direct influence on the change in the total amount of sugars, protein and 10-HDA in royal jelly. By getting royal jelly from rape and lime bee pastures its quality criteria are higher, compared to apiaries with deadnettle plants. When plants don’t distill nectar, artificial carbohydrate-protein feedings have to be applied. It raises the total sugar content in royal jelly, reducing the quality. During the storage of royal jelly amino acid content varies. According to storage method this index ranges from 20% to 50%.
