Researchers Unlock Potential of Date Seeds in Agriculture and Food Research
Researchers from the United Arab Emirates University have discovered a method to valorize date seeds, a major byproduct of the date palm industry, into a valuable economic resource. The study found that low pH-assisted hydrothermal extraction can produce date seed extract (DSE) rich in bioactive compounds, capable of stabilizing emulsions. The findings have significant implications for the agriculture and food research sectors, potentially leading to the creation of new products and applications.
Key Takeaways:
- The study found that date seeds can be valorized by low pH-assisted hydrothermal extraction to yield date seed extract (DSE) rich in bioactive compounds.
- The parameters of extraction time, temperature, pH, and date seed concentration significantly influence the total polyphenol content and emulsion droplet size of the extract.
- The optimal values for extraction time and temperature positively impact both bioactive compounds and emulsion stability.
- The predictive response surface models effectively captured the trends, enabling process optimization for the extraction process.
- The research concluded that date seed extract-stabilized emulsions have good storage stability under neutral to mildly acidic conditions.
- Further studies are recommended to improve salt stability and expand functional applications of DSE-stabilized emulsions in complex food or pharmaceutical systems.
Statistics:
- The extraction process used an I-optimal design to evaluate the effects of extraction time (30-150 min), temperature (30-50 °C), pH (1-6), and date seed concentration (DSC, 5-25 %).
- The study found that time and temperature positively impacted both total polyphenol content and emulsion droplet size.
- The optimal values for pH and DSC followed quadratic trends, with optimal values balancing bioactive release and emulsion droplet size.
- The extraction process resulted in date seed extract (DSE) rich in bioactive compounds, capable of stabilizing emulsions.
