EFFECTS OF FEEDING POLLEN SUBSTITUTES ON THE ROYAL JELLY AND HAEMOL YMPH OF HONEYBEES [PDF]

Journal of Plant Protection and Pathology, 2002
Haemolymph protein and quality of royal jelly produced by honeybee colonies fed only on pollen substitutes were compared with those of natural colonies. These pollen substitutes were check pea-milk and defatted soy flour.

Therapeutic Properties of Bioactive Compounds from Different Honeybee Products

Frontiers in Pharmacology, 2017
Honeybees produce honey, royal jelly, propolis, bee venom, bee pollen, and beeswax, which potentially benefit to humans due to the bioactives in them. Clinical standardization of these products is hindered by chemical variability depending on honeybee ...

Potential protective effect of Trans-10-hydroxy-2-decenoic acid on the inflammation induced by Lipoteichoic acid

Journal of Functional Foods, 2018
Royal jelly (RJ) is known as a functional food for its diverse health-beneficial properties and complicated chemical compositions. Trans-10-hydroxy-2-decenoic acid (10-HDA) is the exclusive lipid component in RJ. In the present study, the in vitro anti-inflammatory effect of 10-HDA in LTA (Lipoteichoic acid from Staphylococcus aureus) induced RAW 264.7

Total Protein and 10‐Hydroxy‐2‐Decenoic Acid Content, In Vitro Bioaccessibility, Antibacterial, and Antidiabetic Properties of Royal Jelly Collected at Different Harvesting Times

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
In this study, the total protein content and 10‐hydroxy‐2‐decenoic acid content were determined in royal jelly collected at the 72 and 144 h. In vitro bioaccessibility, antibacterial, and antidiabetic properties of royal jelly collected at the 72 and 144 h were also determined. ABSTRACT Royal jelly has received interest as a functional food.
