Abstract :
Royal jelly is an important functional food item that possesses several health-promoting properties. Royal jelly is a viscous jelly substance and milky secretion contains 62 to 68.5% water, 11 to 18% protein, 7 to 18% sugar, 2 to 8% fat, and at least 1.4% 10-hydroxy2 - Decenoic fatty acid and less than one percent of vitamins and minerals. The health-promoting properties of Royal Jelly include; Immunomodulatory and Anti-inflammatory Activities, Increases fertility and sexual vitality, Reducing the side effects of chemotherapy and radiation therapy and improving the quality of life of certain patients, Improving memory, and Reducing the risk of dementia and Alzheimer's disease, Anti-diabetic, Regulates blood pressure and prevents cardiovascular disease, Reduces the damaging effects of Rheumatoid Arthritis and Antibacterial and Antiviral Activities. It's recommended that sublingual absorption can be more efficient overall for Royal Jelly than intestinal uptake. The storage condition (4 or -18°C) and Royal jelly dosage are critical. On the other hand, taking Royal Jelly, especially in the overdose, may lead to an allergic reaction. Since the specific gravity, moisture, and storage condition of Royal Jelly are different from honey, in a mixture of honey and royal jelly, Royal Jelly is exposed to oxygen, then spoilage occurs. For this reason, this method of use, a mixture of honey and royal jelly, is not recommended. Also, the use of Royal Jelly in the form of capsules, due to swallowing and lack of oral absorption, is not recommended. The research and development unit of the Kooze Asal knowledge-based Company, with new knowledge in Pure Persian Royal Jelly processing, has been able to develop a domestic production technology of Dragée Royal Jelly (DRJ) by international standards. Freeze-dried royal jelly goes through a process of dehydration, also known as lyophilizing, to remove the water by high vacuum at low temperature. This process does not include heat or chemicals. Lyophilized royal jelly in DRJ maintains all the nutrients of the fresh product and allows for storage at room temperature and longer shelf life. Pure Persian royal jelly is harvested from Kooze-Asal beehives, depending on the quality charter of the Association of Producers of Royal Jelly. Sucking/Chewy Dragée, named DRJ is composed of freeze-dried royal jelly and honey with natural coating and contains no additives, dyes, or added sugars. In this article, we review the research of recent years on the unique properties of this supplement for a healthy lifestyle called dragee royal jelly (DRJ).
