Summary
Immobilizing propolis compounds onto whole pollen grains created pollen-propolis beads. These beads offer enhanced antioxidant activity and improved release properties, presenting a more valuable healthy product.
Area of Science:
- Bee product research
- Food science and technology
- Biomaterials engineering
Background:
- Pollen and propolis are bee products with health benefits.
- Raw propolis has limitations in consumption and food formulation due to ethanol extraction, taste, and smell.
- Immobilization of propolis compounds can overcome these limitations.
Purpose of the Study:
- To immobilize propolis active constituents onto whole pollen grains.
- To create a novel pollen-propolis bead product.
- To evaluate the properties and potential of the new product.
Main Methods:
- Gas Chromatography-Mass Spectrometry (GC-MS) for chemical composition analysis.
- Spectrophotometry to measure total phenolic content and antioxidant activity.
- Evaluation of release properties in simulated digestive systems.
Main Results:
- Achieved 53% immobilization efficiency.
- Pollen-propolis beads exhibited higher phenolic and flavonoid content than individual components.
- Pollen-propolis beads demonstrated superior antioxidant activity (ferric reducing activity).
- Enhanced release properties of pollen-propolis beads in simulated digestive systems.
Conclusions:
- Pollen-propolis beads represent a valuable healthy product.
- The synergistic action of pollen and propolis enhances product value.
- Immobilization on pollen grains is a viable method to improve propolis utilization.
