Summary
Fortifying plant-based beverages with selenium microparticles enhances selenium bioaccessibility significantly compared to traditional methods. This approach offers a promising strategy for effective selenium supplementation to meet daily nutritional needs.
Area of Science:
- Nutritional Science
- Food Science
- Biochemistry
Background:
- Selenium (Se) is a vital micronutrient for human health.
- Increasing selenium intake through fortified foods is a key nutritional strategy.
- Developing bioaccessible selenium species is crucial for effective supplementation.
Purpose of the Study:
- To produce selenium microparticles (selenate, selenite, Se-organic) via microencapsulation.
- To fortify plant-based beverages (PBBs) with these selenium microparticles.
- To evaluate the stability and bioaccessibility of selenium in fortified PBBs and its contribution to Recommended Daily Intake (RDA).
Main Methods:
- Microencapsulation techniques were used to produce Se-microparticles.
- Commercial PBBs were fortified with the produced Se-microparticles.
- In vitro bioaccessibility was assessed using the INFOGEST method.
- Total and bioaccessible Se levels were quantified using ICP-MS after acid digestion.
Main Results:
- The produced Se-microparticles demonstrated stability in size and form during storage.
- Fortified PBBs exhibited high selenium bioaccessibility, ranging from 77% to 94%.
- Selenium bioaccessibility from microparticles in PBBs was superior to that from isolated selenium salts.
Conclusions:
- Selenium microparticles are stable and highly bioaccessible when incorporated into plant-based beverages.
- This microencapsulation strategy offers a superior method for selenium fortification compared to traditional approaches.
- Fortification of PBBs with Se-microparticles presents a promising avenue for effective selenium supplementation to meet human nutritional requirements.
