Summary
Natural deep eutectic solvents (NADES) with β-cyclodextrin significantly enhance anthocyanin extraction and stability for functional gummies. This green method boosts antioxidant capacity and yields more stable, functional gummies compared to traditional approaches.
Area of Science:
- Food Science
- Natural Product Chemistry
- Green Chemistry
Background:
- Anthocyanins are valuable natural pigments with antioxidant properties but suffer from poor stability.
- Developing stable, functional food products requires efficient extraction and stabilization methods for anthocyanins.
- Natural deep eutectic solvents (NADES) offer a sustainable alternative for extracting bioactive compounds.
Purpose of the Study:
- To evaluate the efficacy of NADES combined with β-cyclodextrin for anthocyanin extraction and stabilization.
- To compare the yield, stability, and antioxidant capacity of anthocyanins extracted using NADES versus traditional methods.
- To assess the suitability of the NADES-extracted anthocyanins for incorporation into functional gummies.
Main Methods:
- Extraction of anthocyanins from plant sources using a specific NADES formulation (CD-CA: β-cyclodextrin and citric acid with water).
- Comparison of anthocyanin yield and profile with traditional HCl-EtOH extraction.
- Assessment of radical scavenging capacity, photostability, and thermal stability of the extracts.
- Incorporation of Crimson Glory extract into pectin-based gummies and evaluation of anthocyanin retention and antioxidant capacity during processing and storage.
Main Results:
- The CD-CA NADES method increased anthocyanin yield by up to 39% compared to HCl-EtOH.
- Seventeen anthocyanin compounds were identified, including novel ones not found in HCl-EtOH extracts.
- CD-CA extracts showed 1.29-fold higher radical scavenging capacity and improved photostability and thermal stability.
- Anthocyanin retention in gummies was higher with the CD-CA extract (11.01% higher post-processing, 11.31% higher after 30-day storage).
- CG-CD gummies exhibited 1.32-fold increased free radical scavenging capacity.
Conclusions:
- β-cyclodextrin-based NADES provide a green and efficient method for extracting and stabilizing anthocyanins.
- This approach significantly enhances the antioxidant capacity and stability of anthocyanins in functional gummies.
- NADES represent a promising functional ingredient for developing stable, high-value food products.
